Metal Building - Erection, Installation
andMaintenance Manual
The Metal Building Erection, Installation and Maintenance
Manual has been prepared to assist builders in order to erect
buildings properly, quickly and safely.
This manual consists of brief outline of building terminology,
safety, tools required for installation of Pre- engineered building,
engineering documents, anchor bolt setting, material handling
and storage, and building maintenance. It also coves erection of
primary and secondary structures which includes column,
rafters, Purlin, grits, and roofing and walling sheeting.
The erection information presented in this Manual is provided as
a supplement to the erection drawings supplied with Building.
This Manual is intended as a guide, to be used in conjunction
with erection drawings, to help plan and organise installation
work at site. It will help to identify parts, establish a safe erection
sequence, speed up assembly and point out any areas or
procedures requiring special emphasis or attention. The building
erection drawings will always govern with regard to construction
details and specific building parts.
It is strongly recommended that before begin, familiarise with all
the building components and connection details as well as the
sequence of erection. This will help to plan the work and avoid
unnecessary delays during erection.
The builders who refer to the contents of this manual must pay
regard to current regulations for site safety. The builders are
responsible for maintaining strictly the current legal regulations
of labour safety during erection of buildings.
In line with quality objectives and quest for excellence,
Tata BlueScope Steel is now seeking long-term relationships
with qualified builders to provide the best & safest steel building
erection service to our customers.

2Built Up Framing Systems
8
This basic framing illustration is designed as an aid in the
identification and location of the structural members and
components used in the construction of building structures.
There are a number of different types of structural systems
available from Tata BlueScope Steel to provide a large range of
space, support and protection possibilities and in light, medium
and heavy design loads. Generally, part references and usage
will follow a similar pattern for all buildings.
Main FrameMain frames consist of two or more columns spanned by roof
beam which support the roof structurals. All wide span buildings
are clear span structures with the exception of MRF buildings
which also require the use of interior columns.
Tata BlueScope Steel offers vide range of frame options to suit
the customers requirement at competitive rates. The following
options are available in frames to the customer as;
Clearspan
Clearspan frames are available in straight or tapered columns for
double slope and single slope profiles, and are used with single
slope width extensions (units supported by an adjacent unit, i.e.
WX frame).

double slope and single slope profiles. Frame modules may vary
across the building width, independently by frame within the
building unit. Symmetry of modules is not required (i.e.: 60', 60',
50' would be an acceptable frame module combination for a 170'
wide MRF).
Double Slope Profiles -
1. Frames - MRF
The MRF Frame has a modular double slope profile with tapered
sidewall columns. Material used in this frame is optimised to the
specific width and height requirements.
MRF Columns: All columns are one piece tapered members
with the outside flange plumb. They can be ordered flush or with
8" inset from the sidewall structural line.

3. Frames - WX
The WX Frames has a clearspan single slope profile with a
straight sidewall column at the low side. WX frames are
designed to attach to the low eave of another unit so as to match
roof slope and eave elevation of the adjoined unit.
- WX frames must attach to a rigid frame such as an LRF for
structural stability.
- WX frames have all pinned joints while rigid frames have fixed
joints which make them "standalone" stable.
- WX frames with high side columns are not stable without the
support of the adjoined rigid frame because the high side column
has a pinned joint also. Since beam and post endwalls use
pinned joints, a WX intermediate frame cannot attach to a beam
and post endwall.
WX Columns: All columns are one piece straight members with
the outside flange plumb. They can be ordered flush or with 8"
inset from the sidewall structural line.
WX Roof Beams Roof beam profiles may vary. The top flange
of the roof beam will be straight to form the roof slope. The
shape of the web and bottom flange will vary as required to opti-
mise the material used to manufacture the beam.
4. Frames - ENDWALL
Endwall frames can be a pinned endwall frame or semi- rigid
endwall frame. In either case, the frames are designed only for
the loads on the endwall and are NOT designed for future expan-
sion. Both frames use an H-section roof beam.
10
Semi - Rigid Endwall Frames
The semi-rigid endwall frame uses a light Clearspan or Modular
rigid frame with straight columns and endwall posts rotated 90
degrees. This frame is NOT expandable in the future.
Expandable Endwall Frames
Utilises an interior frames located 2' inset from the endwall struc-
tural line (with pinned endwall posts) which allow for future
length expansion of the building. A building with possibility of
Future Expansion must be specified at the beginning of the proj-
ect in order to be considered in the design and highlighted on the
drawings.

Erection Tools and EquipmentsAll tools and equipment used for installation must have test
certificates and calibration certificates if required. The
concerned Product Consultant / Project Safety Officer /
Project Manager or competent person should check the
certificates before using the equipments on site.
Mobile Equipment
• Mobile equipment includes delivery trucks, truck cranes,
hoists etc.
• Only certified mobile equipment and qualified operators are
permitted to enter the site.
• All power lines must be barricaded or flagged when
there is a danger of contact by mobile equipment. Lines,
which could be reached accidentally, must be de-energised
or otherwise made safe before any work is started.
• No equipment is to be operated over the top of power lines.
• Never operate equipment closer than 4.5 m to a voltage line
of 220 volts or more.
• Only an appointed signalman may give signals to the
operators except for emergency stop signal.
• Stay clear of moving equipment whenever there is danger
from swinging booms, crane cabs, suspended loads, etc…
• Accessible areas within the swing radius of the rear of
the rotating superstructure of the crane shall be
barricaded.
• Avoid walking near or walking under a suspended
load of hoisting operations.
• All suspended load must have tag lines.
• Prior to start of any lifting work, the location for
position of the cranes and materials laid down at the
erection areas shall be identified. Job safety and risk
analysis shall be done (you can also refer to
Customer Site Installation Safety Procedure). All
cranes and its safety devices and rigging equipment
shall have appropriate certificates and suitable
capacities for the intended lifting operation. All crane
operators shall be experienced and have valid
licenses from relevant government authorities. The
crane load charts should be always available in the
operators cabin.
• The crane shall be positioned and out riggers set
prior to lifting. Boom length, boom angle, operation
radius and safe lifting capacity shall be assessed as
per crane manufacturer's load chart prior to the lift.
• Damage to completed paintwork shall be
avoided/minimised at all stages of the erection work
by using nylon slings or belts and protective pads in
26
contact with steel work or by lifting with anchor
shackles through bolt holes.
Tag lines and load lines
• Tag lines and load lines must be carefully inspected
each time they are taken down. Defective or
damaged rope or cable will be cut immediately to
prevent further use.
• Before any load is lifted with any rigging for the first
time, a qualified supervisor will inspect all portions of
the rigging and a static load test will be performed i.e.
lift the load clear of the ground, hold for final
inspection of slings, shackles etc. prior to lifting the
item into the air.
• Tag lines must be flagged where they cross any path
or roadway.
Slings
• All slings are to be inspected each day prior to their
use. This includes chain, wire rope and synthetic
slings and their attachments, i.e. master links,
alligators, clips, hooks, quick-alloys etc.
• Defective cables and slings shall be cut and
destroyed immediately.
• In lifting operations, protect slings from abuse.
Protect slings by padding sharp corners, and never
jerk the load. Jerking may triple the load on the sling.
• Hang up slings when not in use.
• Never overload a sling.
Scaffolds
• Scaffolds shall be planned and installed in a way so
as not to restrict crane access and boom clearances
or make erection activities difficult.
• Scaffolds must always be placed on a firm ground
position and foot bases always supported by
adequate wood planks with minimum size
200 x 200 mm.
• Scaffolds installed separately must be fixed to static
structure at a minimum space of 1.5 m and every
upper scaffold frame must be fixed to the below scaf
fold by steel rod or scaffold tubing in a safe method.
• All scaffolds shall be installed with handrails, midrails,
ladders, and a platform at every floor level. Handrails
and midrails should be steel pipe D 50 x 2 mm and be
fixed at 0.5 m and 1 m above each platform. At each
ladder anchor points, an appropriate wire 'tie-off' shall
be used to tighten.
• Access-to-roof scaffolds shall have at least 6 support
feet as recommended.

• Shut down and isolate the power source of machinery
and use extreme caution when cleaning or making
adjustments.
• Be sure the machine is inoperable before removing
safety guards when making repairs or adjustment.
• Report all the frayed, broken equipment to team
leader.
Tips onGas Cutting, Welding and Grinding
Gas Cutting, Welding
• Only qualified, properly trained, and instructed
personnel are permitted to use oxygen, fuel gas, weld
equipment. The Project Safety Supervisor must
perform an initial check and record the document
prior to permitting use.
• Keep oil and grease away from oxygen equipment.
• All gas bottles must be stamped and approved.
Compressed gas cylinders shall be handled carefully.
Avoid jarring, bumping or dropping them. Always
secure in an upright position.
• Cylinder shall be moved by cart, never rolled. Use a
cradle or holder when lifting cylinders with crane,
never use a magnet.
• Protective caps shall be kept on cylinders when not in
use and when being transported.
• Oxygen cylinders in storage shall be separated from
fuel gas cylinders by a minimum of 6m or a fire wall
1.5 m high.
• Flash - back protection shall be provided by an
approved device that will prevent flame from passing
into the fuel-gas system.
• Torches will not be used as a hammer to remove slag
or scale.
• Before burning, welding or heating, the worker shall
be responsible for checking conditions on opposite
side or underside to see that all danger of fire or injury
is eliminated. A proper fire extinguisher shall be made
available.
28
• Never heat an object lying flat on a concrete floor. Be
sure there is an air space between the material and
floor as concrete will explode under extreme heat.
• Never leave a torch inside a vessel or closed
container. A leak could be the start of a disastrous explosion.
• When leaving the area, turn gas off at the
inlet to the hose first and then at the torch. Make
certain that there are no leaks.
• Inspect all torches, hoses, gauges and other burning
equipment regularly. ALL GAUGES MUST BE
MARKED FOR INTENDED SERVICE.
• Keep hoses clear of spark and hot slag area.
• All hose connections shall be screw/thread clamps.
No tie wire for connection shall be allowed.
Portable Grinders
• Only qualified, properly trained, and instructed personnel
are permitted to use a portable grinder. The Project Safety
Supervisor must perform an initial check and record the
document prior to permitting use.
• Grinders shall be equipped with guard at all times.
Guards shall not be removed or altered. Only use a
grinding disk for grinding and cutting disk for cutting.
• Must not attempt to change a wheel without first
getting authorised and adequate instructions. Always
be sure to check the speed on the label against
speed for conformity.
• Check to be sure that the wheel is properly mounted
before starting a grinder. Straight wheels will be
mounted between matching safety flanges at least
1/3 the wheel diameter. The nut will be tightened
securely but not excess, which could crack the wheel.
• When first starting a grinder it shall be held under a bench
inside the job or shielding and run for about a minute to
prevent being struck by a piece of broken steel with a defect
or excess speed causes it to fly apart.
• Cup wheels shall be used on the face only.
• Straight wheels shall be used on the circumference
only, never on the sides.
• Banging a grinding wheel against the work will not
clean the wheel and may cause the wheel to break.
• Never force a wheel by using excessive pressure.
• Handle grinders with care to prevent damage from
dropping. If you drop a grinder, have it checked
before using. Do not handle grinder by electrical cord
or air hose.
Always stop the wheel on the work piece before setting the
grinder down. When you set a grinder down do not rest it on the
wheel.

Prior to commencement of erection work, it is essential to have
a clear understanding of the engineering documents. In the case
of erection, we specifically refer to Erection drawings and
Shippers list.
Erection drawings to be used at site should be 'ISSUED FOR
CONSTRUCTION' and be the latest revision. 'FOR APPROVAL'
drawings should never be used for the works. The revision
boxes at the bottom right corner of each sheet indicate the latest
status, i.e. “For Approval,” “Issued for construction”, “Revised as
Noted,” etc.
I. Anchor Bolt Setting Plan
This drawing shows the layout of all anchor bolts, normally on
one sheet, but for very large buildings, could be on two or more
sheets. Erection drawings are not to scale, so do not attempt to
scale any dimensions. The drawings are proportioned although
sometimes this can be misleading, and care is needed in
reading drawings. All dimensions are in millimetres.
The anchor bolt layout contains an anchor bolt schedule, which
is in the form of a table showing quantities and sizes of anchor
bolts.
The key plan shows center to center dimensions, bay spacing
dimensions, bolt setting details and critical dimensions for the
span. The details show if grout is required under columns along
with grout thickness and anchor bolt projection. Adherence to
anchor bolt setting tolerance is important and shall not exceed
the deviation laid down in the standards.
II. Roof Framing Plan
The roof framing plan shows the purlins, bracing and
miscellaneous details. Part numbers for purlins and bracing are
shown, also sag rods (where applicable), and strut tubes etc.
The drawings should be studied very carefully otherwise it is
quite possible to overlook critical details such as nested purlins,
strut purlins and strut clips.
III. Cross-Section
The cross-section is one of the most important drawings as it
contains a lot of vital information. Columns and rafter references,
purlins, girts, vertical and roof bracings, connection details, bolt
schedules, flange brace schedules and other details as
applicable, such as strut tubes, flashing etc.
In conjunction with the Erection drawing it is possible to find out
the number of members required. This being essential during the
pre-planning stage of erection, and cross-checking to be done
with the shipper list before receipt of material at site. The
cross-section drawing may be typical throughout in standard
buildings or in more complex jobs, there may be several
cross-sections, identified by grid numbers.
IV. Roof Sheeting Layout
All roof panels are shown with length and part number. Panel lap
details are shown, also skylight and downspout positions.
Standard details of fasteners, trims and insulation are included.
It is very important to check the starting dimension of the
sheeting, from the steel line.
V. Sidewall Sheeting and Framing
Depending on the job, sidewall framing and sheeting may be on
one drawing or more. The framing elevation shows the position
and part numbers of girts, eaves struts, bracing and sag rods.
The sheeting elevation shows the panel positions with length
and part numbers. Eave trims, gutters and downspouts are
shown with part numbers. Standard details are included which
indicate the number, size and position of fasteners and other
trimming details. End-walls are detailed similarly.
VI. Other Drawings
Other drawings may include crane beam layouts and details;
Mezzanine layouts and details; Accessories such as Sliding
Doors, Roll-up doors, personnel doors, windows, louvers and
ventilators.

VII. Shipper List
The shipper list supplied with the erection drawings is the
customers Bill of Material. The BOM comprises a cover sheet
which includes job number, building number and phase,
customer name, Location, and Building size. The cover sheet
also shows the number of phases in the building, any revisions,
plus any special notes.
The Shipper List has 7 columns indicating
1. Serial number
2. Part number
3. Quantity
4. Revision number
5. Description of part
6. Colour
7. Length of item
The last page indicates the total BOM quantity of items. The
Shipper List is a comprehensive list of total parts/items in a
particular building and it is a reference to the items shown on the
Erection Drawings and should be used to double check items
against the packing list.

If the foundation has been poured, check to see that it is square
and level. If the floor slab has not been poured, check all
elevations for column and post locations. Concrete should be
chipped or grouted where necessary to provide a level surface
at the required elevations
Guidelines for Setting of Anchor Bolts
• Anchor bolts shall be set in accordance with Tata BlueScope
Steel issued 'FOR CONSTRUCTION ANCHOR BOLT PLAN'.
• Finalise the FFL with the client or Consultant. Normally FFL is
bottom level of column base plate, in some cases it changes
as per customer requirement.
• Concreting has to be done finally 25 mm below the FFL level
(or as specified in civil drawing). This margin is for levelling
and grouting purpose.
• Establish the reference pillars at 3m away from intersections
of axis and grid lines at all four sides. Top level of reference
pillars should be kept 150 mm above the FFL. (Please refer
sketch)
• Mark the grid lines as indicated in AB setting plan on the
reference pillars and check whether foundation is square.
Squaring can be done by following methods.
A. Diagonal Method
The method is used when building width and length is less then
25 m or when diagonal of total building can be checked by
single measuring tape. In this, centre lines of four corner
pedestals can be marked by calculating diagonal length as per
drawing. Diagonal 'A' and 'B' should be equal to calculated
length as per drawing. Tie the piano wire or thread on the
reference pillars at all four side and mark the internal pedestal
centre line as per bay spacing given in the drawings.
B. Right Angle (3 - 4 - 5) Method
The method is used when building width is less than 30m and
length is less than 50m. In this case angle between two lines can
be set by chart given below. Mark a distance “x” along width and
distance “y” along length of building. Adjust two lines such that
diagonal distance between points equal 'z' .Refer table.
After setting the angle between two lines, measure distances
and establish reference pillars as per grid lines given in the
drawing and close the transverse to confirm the correctness.
Same above procedure is to be followed at other corners of bldg
and establish reference pillars and mark centre lines of
remaining pedestals as per sketch given below. After marking
centrelines of all pedestals check diagonal between individual
pedestals and anchor bolts.
C. Theodolite Method
Buildings larger than 30m wide and 50m long should be squared
with the help of theodolite. Be sure to check condition and
calibration of theodolite. Set the theodolite over corner
intersecting reference pillars. Sight along the building line mark

All materials are carefully inspected and crated before leaving
Tata BlueScope Steel plant and accepted by the transportation
company as being complete and in first class conditions. It is the
carrier responsibility to deliver the shipment intact.
It is the consignee responsibility to inspect the shipment for loss,
damage and shortage when it is delivered. Instructions for mate-
rial inspection and handling any resultant claims for damages or
losses are thoroughly covered in a check sheet located in the
same packet containing the shipping manifest.
Handling and placement of material will vary according to size,
site conditions and equipment available. Whenever practical,
located and stored in and around the building site where it is to
be used.
For example:
- Rigid frame columns can be laid in position for raising;
- Roof beams / Rafters can be stacked for subassembly at
locations accessible for setting;
- Secondary structural and braces can be divided and
located according to requirement of each bay.
Access area is plan such that crane / equipment can be fully
utilised and down time kept to a minimum. Most builders find it
advantages to leave an access area at one end of the
building and running the full length of the building for
maneuvering erection equipment.
Material that will not be used during the erection of the framing
should be stored in area that offer protection from physical dam-
age and covered to provide protection from the weather.
The Procedure
1. Shipping department shall give the Product Consultant /
Builder sufficient advance notice for all site deliveries to
ensure there is a plan for unloading, so that Product
Consultant / Builder can mobilise suitable crane and
manpower for unloading of material.
2. A delivery note is always enclosed with the supplied
materials to clarify name of project, location, building
number, type of materials, quantity, date of delivery, etc.
3. Upon arrival of materials at the storage yard, the Builder's
material controller will match delivery notes and shall verify
the consignment. The material controller, then, reports to the
site supervisor the received material list and quality
condition.
4. There should be an Appointed Person by Builder who will be
having overall control of all lifting operations on site and the
Appointed Person must ensure that everyone in the crane
team has studied this manual and is aware of the correct
procedures to adopt in the cases not covered by this
manual.
5. Planning the Lift
Planning the lifting operation is essential to ensure that the
lift is carried out safely and efficiently. The following points
must always be considered:-
• Where the load is to be picked up from
• Where the load is to be placed
• What areas are to be passed over
• Proximity of the other contractors workers
• Any obstructions in the way
• How the load is to be slung
• How the slings are to be removed
• How the crane driver will be directed
• The weight of the load
• The weather
6. The Lift
a) Before Lifting
Only authorised slingers / signallers should sling the loads.
After slinging, but before lifting, the following must be
considered:
• Are the slings undamaged and properly attached to the
load?
7Material Management at Site
34
• Is the crane hoist rope vertical?
• Is the load free to be lifted, i.e. not fixed to anything else?
• Is the safety latch on the lifting hook closed?
• Are all personnel clear of the load?
• Is the landing site prepared to take the load?
• Are the legs of a multi-legged sling equally loaded?
• Is there a slinger / signaller in position to receive the load?
• Are the weather conditions acceptable?
• Are there any obstructions above the load preventing a
straight load?
b) Taking the weight
Be sure to hook the slings to components with the right no.
of points and position so that the load does not get
damaged. A spreader should be used for lifting long
components. Nylon belts or cloth slings with suitable SWL
shall be used for unloading the materials to minimise the
damage. Then, and only then, should the load be lifted. As
the load comes onto the crane, the jib may start to deflect
(especially telescopic jibs). The crane operator must correct
this so that the hoist rope remains vertical. The signaller
should also be aware that the load may swing.
Now slowly lift the load a short distance above the ground.
Then check that:-
• The load is balanced and stable
• The legs of the sling are at the correct angles
• Any packing pieces are in place and sound
• The load itself is not over-stressed, especially when lifting
packing cases like that of gutter and flashing boxes, sheet
bundles etc., which can fail under the loads applied due to
lifting.

c) During the Lift
The load can now be lifted and moved to its landing area.
While in the air avoid:
• Passing over personnel working on the site
• The public
• Power lines
• Projecting scaffolding
Make sure that all personnel are clear of the load moving path.
d) Landing the Load
The load should be landed gently to ensure that it is not
damaged, and that the crane does not receive any shock
loading.
Before landing the load, check that;
• The landing area will take the weight of the load
• There is sufficient space for the load
• There are strips of timber or similar supports on which to
land the load such that the slings can be easily removed by
hand.
The signaller must ensure that he is in a place of safety
when receiving the load, ensuring that he cannot be crushed
between the load and a fixed object or pushed over an open
edge.
e) After the Lift
Take care with bundles of tubes and similar items as they
can collapse when landed, and pipes can roll, so make sure
suitable blocks are used to prevent this from happening.
Never drag chains from beneath the load and jump down
from the moving trailer.
7. Webbing slings, or any sling made from synthetic fibres,
should be examined before and after every lift as they are
vulnerable to being cut by sharp edges. If there is any sign
of a cut or fraying in the fabric, they should be taken out of
use and examined by a competent person.
8. All materials received onsite shall be visually inspected by
the site supervisor for any damage. Material Inspection
Report should
be sent to HO / Factory on the same day.
Remedial works to the damage shall be undertaken
immediately, if possible, to avoid any delay to erection.
36
Do not stand wherea moving load could trap or crash you
Never jump down from the moving trailer
1. Choose a firm and dry area for storage.
2. The material shall be stored above ground level with timber
packing.
3. The materials shall be stacked in locations according to the
building/areas, and should be at a lifting position adjacent to
the area to be erected. This is to facilitate the sorting and
delivery during the erection.
4. The materials shall be stored separately, above ground
level on timber packing. They shall not be stacked directly
on top of each other but must be separated by 50mm thick
timber, and shall not be stacked in contact with other steel
components and must be separated by a minimum 250 mm
gap.
5. Particular care shall be taken to stiffen free ends at a
distance of 200mm from the ends to prevent permanent
distortion. Incorrect handling may break crates and
materials particularly sheeting may become beyond use..

Generally, most structures follow a basic sequence of erection
that enable you to utilise personnel and equipment as effective-
ly and efficiently as possible. For example, after several bays
have been erected and plumbed and squared, work crew can
start on other phases of the erection simultaneously as the fram-
ing progresses; overhead and sliding door may be installed; side
wall and end wall panels can be applied after several bays are
completed; overhang canopies and fascia can be installed after
the wall panel are up; roofing crews cab follow.
Pre-lift checklist and Meeting
The required material, accessories, crane, tools, tackles and
safety equipments shall be checked for availability at site and
ready to be used prior to starting of lift.
A pre-lift meeting shall be held before lifting any structure to
ensure everybody at site understands the lifting method or step
for the erection of the entire building. The Project Manager /
Product consultant of BSBS shall check details of the specifics
given in the check list attached in the annexure.
Framing Sequence -The general sequence of framing is as follows:
1. The brace bay closest to the endwall, standard location for
brace rods is usually the first interior bay. Be sure to refer to
your erection drawings for specific bracing requirements.
2. Plumb and square the braced bay
3. Install roof and wall braces
4. The end wall adjacent to the braced bay including secondary
structurals.
5. The intermediate bay adjacent to the braced bay
6. Continuous erection sequence, making sure each
intermediate bay is aligned before erecting succeeding bays,
until the structure is completed.
Note: temporary bracing shall be introduced wherever necessary
to take care of all loads to which the structure may be subjected,
including equipment and the operation of same. Such bracing
shall be left in place as long as may be required for safety.
Where ever piles of material erection equipment or other loads
are carried during erection, proper provision shall be made to
take care of stresses resulting from such loads.
The structural frames and other parts of the building can be
erected in various ways which will depend on the following key
factors:
• The type of structures such as: small clear span, large
clear span, low rise building, high building, o p e n - w e b
structure, etc.
• The availability of equipment such as cranes, winch,
manually lift, etc.
• In case of long rafters / members spreader bars multiple
cranes should be used
• The site conditions.
• The experience level of the erectors
Step 1 - Anchor bolt checking
Check the anchor bolt casted for compliance with details
provided in Anchor bolt setting plan. Check whether
concerned template goes freely into bolts. If not, make the
bolts vertical with the help of pipe without damaging the
treads of anchor bolts. This pre check is required to avoid
time lost during the actual correction.
Check the foundation levels. In buildings that require grout,
shim packs are placed in the centre of bolt pattern. Buildings
without crane system generally do not require grout, but
variances in concrete levels may necessitate the use of
shims. Level the base of RCC pedestal by keeping required
shims, check the level with Dumpy level. Top level of all
8Frame Erection Procedure
38
shims should be at same level. Shim plates should be
provided by Builders. In any case, nuts should not be used
as shim plates.
The sequence / method of erection shall be studied and
planned so that execution can be carried out in a safe,
economical and efficient manner. There are certain erection
practices that are in general use and have proven sound
over the years. Below are typical instructions applied for a
LRF and MRF structure.
Step 2 - Install Columns at Braced BayAlways erection should start from braced bay. Here bays
2-3 and 4-5 are braced bays.
• Check position and part mark of column
• Install column A2
• Tighten anchor nuts
• Set up scaffold or ladder at columns
Tie temporary bracings on two sides of column. Temporary bracing should be either PP rope of 20 mm dia or wire rope of 12 mm dia minimum.
• Check the plumb of column on either side
• Slightly release the load on slings and
Check the stability of column
• Remove the slings
Step 3 - Install column 'A3' as per [step 2]
Step 4 - Fixing of Girts
• Fix all the side girts and tie them between each column
• Rope with safety-lock hook to lift girts
• Tighten the bolts with normal torque
• Install temporary bracings on 2 sides of each column
• V shape cleats used to fix the other cable end on to 2
anchor bolt heads
Step 5 - Install other side wall columns
• Install other sidewall columns E1 and E2 and girts by
repeating Step [2], Step [3] and Step [4].
Step 6 - Install the 1st Rafter.
• Shift all material for the first braced bay erection.
• Identify the rafter part mark.
• Assemble RF-2 on the ground with correct size of bolts
near as possible to the lifting position.

• 50 mm thick wooden block to be used to support
members for assembling.
• Torque wrench to tighten hi-strength bolts with minimum
recommended torque (lookup in the torque table for
Hi-strength bolts.)
• Attach temporary bracing at every 6m and fly bracing to
rafters. Attach support pipes D 50 x 2 mm x 2 M and
safety static lines to rafters. Two pipes fixed to in-flange
and out-flange of rafters, one at 1m distance from eave
and the other right at the top ridge of rafter end, the pipe
on top is used for both roof slopes. Static lines are fixed
from pipe to pipe by brackets at 800 mm high from outside
flange.
• Abrasive paper and cloths are to be used to clean. Touch
up paint by roller.
• Attach the slings to the member at 2 points about 1/4 from
ends ( 3.5 m ) and next-to the purlin cleats toward the
ends.
However, the overhang must be calculated properly to
prevent the distortion of the member caused by the weight
itself. The belt pickup angle also needs to be calculated to
avoid the distortion of material caused by force along the
member. For safety, it is recommended to use more than two
points on member for belts.
• Install assembled rafter with the help of crane to columns.
• Workers on scaffolds at columns to tighten bolts to a snug
tight condition at rafter-column connection plates.

• Temporary bracing at every 6m to hold the first rafter on
2 sides to anchor bolts groups by V shape cleats or any
other immovable object
• Release the crane slightly to check the stability of rafter
before fully releasing the crane.
Step 7 - Install the 2nd Rafter
Repeat the same [step 5] for the second rafter
• But do not release the crane.
• Install purlins and Fly bracings from ridge to eave to hold
rafter in place.
• Fix temporary bracings at 6m each on both the sides of
rafter.
• Rope with safety-lock hook to pull up purlins manually.
• Sash socket spanner for M12 with normal torque.
• Erect roof and wall bracings.
• Release the crane.
Step 8 - Finish 100% the first braced bay
1. Fully install struts, purlins, fly bracing - 100%
• Crane to pick up struts to roof.
• Rope with safety-lock hook to pull up purlins
manually.
• Sash socket spanner for M12 with normal torque.
• Install the static line D8mm to anchor pipes at ridge
and eave of rafter at every 02 bays.
• Install another movable static line (D8mm) from static
lines at eave and ridge moving at the middle of each
bay for installing the purlin bracing safely.
2. Install permanent cross bracing for roofs and sides fully at
this bay
• Leave the bracing in loose condition.
The Alignment (Plumbing and Squaring) is one of most important
activity in the erection Sequence. It is very important to align first
braced bay before proceeding with further erection to avoid
problems when continuing the Erection Sequence.
42
Step 9 - Alignment and Tightening of Braced Bay
• Check the level of Columns
• Check plumb of column on both sides. Plumb of Columns
in the direction of length of building can be made by
tightening and loosening the braced rods. Ensure that
one braced rod is tightened, other rod must be loosened.
The plumb of column along the frame can be made by
temporary bracings.
• Check the rafter alignment by dropping of plumb from
rafter at ridge and at every 6m.
• Rafter can be aligned by loosening and Tightening cross
Bracings.
• Use temporary bracings to get Rafter in alignment if
required.
• Check to be Sure that Ridge point of rigid rafter is over
the centre line of building.
• Make sure that fly bracings are fixed in the correct
location.
• Fully tighten the permanent bracing and all the hi-
strength bolts with correct torque setting.
Key Note:
a) Bolts Tensioning Torque Check
(For Hi-strength Bolts)
1. All hi-strength bolts shall be 100% checked by the team
leader.
2. The site supervisor will do the 10% check and report to
the site manager.
3. Packing/shims, made from material of the same grade,
shall be provided wherever necessary to ensure that the
load-transmitting plies are in effective contact when the
connection is tightened. All shims shall be painted to the
same colour as the main material.
4. Tightening and final tensioning of the bolts in a
connection shall proceed from the stiffest part on the
connection towards the free edges.
5. Re-tensioning of the bolts, which have been previously
tensioned shall be avoided, except that if re-tensioning
is carried out, it shall only be permitted once and where
the bolt remains in the same hole in which it was
originally tensioned and with the same grip.
Re-tensioning of GALVANISED bolts shall not be
permitted. Under no circumstances shall the bolts, which
have been fully tensioned, be reused in another hole.
Touching up or re-tensioning of previously tensioned
bolts which may have been loosened by the tensioning
of adjacent bolts shall not be considered as
re-tensioning.
6. Final tension of bolts shall only be performed after
alignment and level checks have been performed and
found to be satisfactory.
b) Bolt Tightening Sequence
43

1. The following figures show the allowable sequence for
bolt tightening at any joint.
2. The tightening work shall be implemented in two rounds,
the second being done to ensure all bolts are equally
stressed.
3. Allowable torque for bolt tightening and inspection
4. In the completed connection, all bolts shall have at least
the minimum torque applied on specified below when all
bolts in the bolt group are tightened.
5. There is another method of inspecting the bolt tightening
called part-turn method. All nuts in a connection shall be
first tightened (the effort of one person using a 300 mm
long spud wrench). Mark the relative position of each nut
and bolt before tighten a further 1/3 turn.
c) Alignment Check
1. It is the responsibility of the team leader to do the
alignment inspection for 100% of the structure members
while the site supervisor needs to do the re-inspection
and officially report for one main frame and two end
frames.
2. Each part of the structure shall be aligned as soon as
practicable after it's erection. Permanent connections
shall not be made between members until a sufficient
part of the structures have been aligned, leveled, plumb
and temporarily connected in such a manner that the
members will not be displaced during erection and
alignment of the remainder of the structure.
STEP 10 - Install the first end frame
1. Install all side and internal columns at line 1 and girts.
2. Adjust alignment, position and level
• Scaffolds setup at each column

Secondary Structural Connections
Secondary structural consist of the purlins, Eave strut, and girts.
These structural are installed in the bays as the rigid frames are
erected. Widespan buildings may use either simple span or con-
tinuous structurals or both.
PurlinSimple span purlin connection - when simple span purlin are
used, purlin clips are used at purlin - to - roof beam connections.
Clips may be preassembled to the purlins before installation
Continuous span Purlin connection: when continuous purlins
and used, install the bolts finer - tight as it will be necessary to
remove the bolts later in order to lap adjacent structurals. After
the splice is made, the bolts are drawn up tight.
Eave strut
Standard eave struts ar installed using a basic simple span con-
nection and bolt directly to the roof beams.
Girts
Simple span girts terminate at the centreline of the columns and
attach directly to the columns. Continuous girts are assembled to
the columns in the same manner as continuous purlins to the
roof beam. Adjacent ends of girts must be lapped and bolted to
the columns at the same line.

End Wall Erection
Beam and post endwalls can be erected in sections preassem-
bled on the ground including posts, roof beams sections, and
girts. Because of common connections between sections,
reassembly is usually limited to alternating sections.
Layout the structurals in the relative position in which they will be
assembled.
End wall posts may be either single sections or double sections
(two post bolted back to back). If double post construction is
required, bolt these sections together first.
Attach girts clips to endwall posts.
Field notch end-wall girt at corner post location and connect
between corner post and end wall post girt clip. Intermediate
Girts do not require cutting.
Attach roof beam sections between posts. A clip is used to attach
the roof beam to the corner post and a splice plate at inside post
connections. If double end-wall posts are used, the splice plate
is not required.
Raise the corner endwall section into position and hold in place
with crane until secured to the foundation and sufficient second-
ary structurals are installed to stabilise the sections.
Install sidewall girts, eave struts and purlin.
Finish the endwall by raising alternate sections and filling in
secondary structurals and roof beam sections.

CORNER POST TO ENDWALL ROOF BEAM
Intermediate frame endwall
The intermediate frame endwall uses a standard rigid frame
located 2' in from the end of the building. The purlin extend past
the frame to the end wall structural line. Endwall post locations

Purlin clips to purlins
Purlin clips are used to attach the purlins to the endwall roof
beam. The clips can be pre-assembled to the roof beam before
raising the end wall sections.
If the building has a flat roof beam section the purlin clips loca-
tions on the endwall roof beam is varied to maintain the proper
roof slope. Clip locations are determined from the erection
drawings.
Complete bracing
Proper use of bracing is extremely important in the structure to
provide strength and rigidity and for frame alignment. Typical
bracing connections are shown below and it will be necessary to
refer to the erection drawing for specific location and application
of these components.
Brace rod are required in the sidewall and roof at braced bay
locations. Endwall bracing in used only at beam and post end-
wall locations. They are not required with intermediate frame
endwall.
Alternative attachment at column
Flange brace installation
Flange brace are used to provide lateral support to the roof
beam or column and their installation at specified locations is
important in obtaining a sound structure. Flange brace bolt to the
web of the purlin or girts and to the roof beam or column flange.
An exception may occur on some frames near the knee where
the flange are inaccessible. In these instances, threaded studs
are factory welded to the frame braces are usually attached to
the roof beam of the ground, leaving the connections to the
purlin to be made in the air.
Flange brace locations and part numbers are determined from
the erection drawings which also indicate visually the proper
hole in the flange brace to use.

Base angle installation
Base angle is installed around the perimeter of the foundation for
supporting the bottom of the wall panels. The base angle instal-
lation used with a particular wide span building will depend on
the type of wall system specified as indicated in the illustration.
Any of several methods amy be used to attach the angle to the
foundation; preset anchor bolts must be set when the foundation
is poured ; drilled in anchors may be used; or drive pins may be
used. Regardless of the method of attachment, anchor spacing
and minimum shear strength conditions must be met as speci-
fied in the erection drawings. This is particularly important when
panel diaphragm action is dependant upon for wind bracing.
Gable angle installation
The gable angle fastens to the top edge of the purlins and eave
struts at the end wall and is used for supporting the endwall pan-
els. Gable angle is furnished in 20' lengths and the installation
sequence is from eave to ridge.
Gable angle may require filed cutting at the ridge in which case
the cutting dimensions will be indicated on the gable angle erec-
tion drawing.
Gable angle never used on structurals which extend [past the
building structural line. If the endwall has an overhang or fascia,
the gable angle is notched to fit around the purlin and eave strut
and is installed at the structural line location
Sag angle installation
Sag angle serve two purposes; they provide lateral support to
the purlin flange and may also be used to keep roof secondary
structural in alignment for easier roof installation. Except where
57
Part 2 - Metal Building Erection
Fram
e Er
ectio
n Pr
oced
ure
necessary because of design requirements or to satisfy local
building code, sag angles are optional and furnished with the
building as ordered.
As a general rule sag angle is installed at the top location on the
Purlin when ordered for erection alignment of roof structurals
and in the bottom location when required for bracing. Start the
sag angle installation at the ridge and work towards the eave.
The ridge sag angle bolts between the ridge purlins and must be
installed so the short leg of the angle is always at the bottom.
Intermediate sag angle are installed by inserting the tab on the
end of the angle into the slot in the web of the purlin and bend-
ing the tab to lock the angle into position. Tab may be bent down
with a hammer. If the sag angles are installed in the top of the
purlin, the leg of the angle and the tab should face downward. If
the sag angle are located in the bottom of the purlin, the leg of
the angle and bent tab should face upward.
The adjacent sag angle is used between the eave strut and first
purlin. This angle bolt to the web of the eave strut and threaded
rod on the opposite end passes through the purlin web. Two
nuts, one located on each side of the purlin web, are adjusted to
pull the eave member into alignment with the purlin.
On building with a width extension or canopy, a sag rod is used
instead of a sag angle between the eave strut and the adjacent
canopy or width extension purlin. The two nuts at each end of the
sag rod are adjusted to align the purlin with the eave strut.
Sag rod is not required in 4' sidewall overhangs, however an
adjustable sag angle can be used between the building and
overhang eave struts for alignment purpose.
Sag strap installation
Sag strap are used only for bracing the wall structural and not
intended to be used for alignment purposes. Sag strap are usu-
ally installed after the wall panel are in place ot permit easier
alignment of panels and girts.
58
Installation of Wall Panels
The roof of any type of structure is the area most subjected to
problem… the wall most subject to critical inspection. These
areas should receive careful attention during installation.
All our panels are designed to withstand the severest of weath-
er conditions and incorporate design features.
General Procedures
Prior to commencement of fixing, the installer should ensure that
the purlins, girts or battens are truly in place and that the slope
requirements are met. Any adjustments found necessary should
be made prior to proceeding with fixing, as they will be difficult or
impossible to rectify later.
Initial Preparation
1. Scaffolding Preparation
• Erect scaffolds with handrails, midrails and platforms. They
shall be supported from falling by pipe D50 x 2mm x 6M to
ground. The scaffolds shall be tightened on the top to the
roof anchor pipes.
• Scaffolding system will be setup at 300mm away from the
out flange of the Girts. All material shall be moved up
through this 300mm gap.
• The scaffold system shall be used to install all the items on
the wall cladding completely such as girts, wall sheets,
gutters, down-pipes, louvers, doors, windows, etc. which
are above 2 m from the ground. They can only be moved
after finishing the installation for above items at the area.
• Another scaffolding system should be setup ready for the
next walling area so that the installation will not be
interrupted due to the movement of the scaffolding system.
• Workers shall directly attach the safety harness to the
scaffolds or handrails.
2. Electrical system preparation
• Electrical wires and ELCB boxes must be taken to the roof
in a safe condition. They must be supported above ground level.
• The electrical wires should be attached to the anchor pipe
positions to avoid direct contact to roof sheets and purlins.
• ELCB box must be taken to the roof for protection against
electrical short-circuit. Two other electrical cables with 3
plug connections shall be connected to ELCB box and
taken to the installing positions ready for using.
Base condition
Three different types of wall base conditions are used with wall
panels. Before starting paneling, be sure to determine which
condition is furnished with your building.
Metal closure: This metal clo-
sure is intended as a vermin
closure only and is not effec-
tive where a light - tight condi-
tion is required or where con-
trol of air movement is
required.
This closure can also serve as
an effective insulation retainer.
Foam closure: a foam closure
can be used in lieu of or in addi-
tion to the metal base flashing to
effect better light or air closure.
The closure is not opaque so
complete light closure should not
be expected.

Notched foundation: a
notched foundation edge may
be used in lieu of or in addition
to either closure method to pro-
vide a base of wall closure.
Before installing insulation /
wall panels, level the girts with
the wooden blocks. Keep the blocks until the panels to structure
fasteners are installed. The general practice is to install the wall
panel in sequence with the insulation. Align the first panel with
building structural as shown below. Apply the panel over the
insulation and drill required holes in the structural members for
the self-tapping screws. Install the wall panel fasteners and
remove clamps. Trim excess insulation and raise the next pre-
cut run of insulation.
It is extremely important that the first wall panel be installed
plumb. Use a spirit level or transit on each panel.
Adjoining panels are installed with overlapping rib toward the last
erected panel. Position panel to structural making sure that it is
kept plumb. Drill structural members if required and install fas-
teners at lapped rib. Use a chalk line to mark the girt location and
maintain a straight line of screws, thus avoiding mis-drilling and
possible leakage. The preferred procedure is to complete all wall
sheeting before starting the roof sheeting, for smoother fixing of
eaves flashing, closures and eaves gutter.
Installation of Roof Panels
Pull Up the Roof Sheets to Roof
1. Fix the anchor pipe to ground
• Anchor pipe D 50 x 2 mm, 500 mm long fixed at a 300 mm
depth into the ground at parallel 6m distance from each
other, and at 45 degree angle opposite to the building
• Turn buckle attached to the top end of the anchor pipe
2. Install the anchor pipe and static line on the rafter
• Pipes D 50 x 2 mm x 5 M fixed to the out-flanges and
in-flanges of the end rafter at a spacing of 6m from each
other and aligned with the anchor pipes on the ground
• Static line to be fixed from pipe to pipe by brackets at
800 mm height level above the out-flange of rafters
3. Install the supporting cables / ropes from roof to ground
• Put a pipe D 50 x 2 x 600 mm into each supporting cable.
Attach ropes to each pipe for lifting to roof
• One cable end is to be fixed to anchor pipe on the rafter,
while the other end is to be fixed to the turn buckle that was
attached to anchor pipe on the ground
• Turn buckle used to maintain cable tension
4. Lift the roof sheets to roof
• Put each piece of sheet into the sliding pipe, sheet will be
held by steel rods
60
• Each worker at the anchor pipe position on the rafter will pull
the sliding pipe by rope carrying the sheet
• After sheets reach the rafter, they shall be manually moved
onto roof purlins
After enough sheets are picked up for the first bay, another team
will start the roof installation.
Roof Sheeting Sequence
It is advised that both sides of the ridge of a building be sheeted
simultaneously. This will keep the insulation covered for the max-
imum amount of time and the panel ribs can be kept in proper
alignment for the ridge panel. Check for the proper coverage as
the sheeting progresses. One can follow the panel-sheeting as
shown below.
When lifting sheets onto the roof frame ready for laying and fas-
tening, care should be taken to make sure all sheets are the cor-
rect way up with the overlapping side towards the edge of the
roof from which installation will commence. Otherwise, sheets
will have to be turned over and/or turned end for end. Sheet bun-
dles should be placed over or near purlin supports, not at mid
span of the purlins.
Fastener Installation
Correct fastener installation is one of the most critical steps
when installing roof panels. Be sure the fasteners are installed at
locations indicated on the building drawings. Panel to structurals
connections are usually located by eye. It is easy to misjudge the
location of the purlin, resulting in a fasteners off the purlin or
below the sealant at the end lap. The installer should stand 90
degree to the panel, facing the purlin. Drive the fastener in until
it is tight and the washer is firmly seated. Do not overdrive fas-
teners. A slight extrusion of neoprene around the washer is a
good visual tightness check. Always use the proper tool to install
fasteners. A fastener driver (screw gun) should be used for self-
drilling screws. Discard worn sockets, these can cause the fas-
tener to wobble during installation.
Applying Mastic Sealant
Proper mastic application is critical to the weather tightness of a
building. Mastic should not be stretched when installed. Apply
only to clean, dry surfaces. Keep only enough mastic on the roof
that can be installed in a day. During warm weather, store mas-
tic in a cool dry place. During cold weather (below 60 degrees)
mastic must be kept warm (60 degrees - 90 degrees) until appli-
cation. After mastic has been applied, keep protective paper in
place until panel is ready to be installed.
Preparing the Eave
Prepare the eave for the first panel by applying tape mastic
along the eave (outside of the insulation, if any) and leaving
release paper in place. Mastic must be applied in a straight line
and with out voids.
Do not stretch the mastic. Use a knife to cut if necessary. Cut an
inside closure strip as shown above and place starter piece on
top of the mastic. Align the major rib of the closure with the edge
of the endwall roof line. Splice a full closure to the starting clo-
sure and apply along the top of the eave mastic.

n
Along the top of the closures that have been placed along the
eave, apply a second run of tape mastic. Prior to removing paper
backing, check and mark for proper alignment of the first roof
panel. Remove paper and fix the mastic.
Installation of the First Roof Panel
Once the eave is prepared, the first roof panel may be installed.
Check the erection drawings to determine the roof overhang at
the eave. Set the roof panel in place over the inside closure
insuring the major ribs of the panel nest properly with the inside
closure. Align the panel edge with the edge of the endwall roof
line.
With the panel properly placed, adjust the line of panel for
squareness to avoid “Saw toothing” at the eave line. Use a nylon
line projected from the eave strut by a certain distance to give
correct distance and line. Make sure that the panel ribs are kept
in straight line from Eaves to Ridge. Use a chalk line to mark the
purlin location and maintain straight line of screws, thus avoiding
mis-drilling and possible leakage. Secure the panel to the struc-
ture with appropriate fasteners. If the building requires more than
the one panel per run, do not install fasteners at the purlin locat-
ed at the upslope end of the panel. These fasteners will be
installed after the overlapping is installed.
Sealing the Sidelaps
Apply the sidelap tape mastic to the weather side edge of the
lower major rib as shown in the figure. The mastic should only be
applied to clean, dry surfaces. With the release paper in place,
press firmly along the length of the mastic to insure proper adhe-
sion. In removing the protective paper from the mastic, care
should be taken not to pull the mastic away from the panel.
Install the adjoining panel positioning the overlapping rib with
care. Drill, at the center of the clearance holes in the overlapping
panel, required size pilot holes for the lap fasteners. Stitch the
lap with the self-fastening fasteners supplied with the screw line.
Never allow the mastic to be placed to the inside of the screw
line.
Installation of Remaining Roof Panels
With the first panel run installed and secured and sidelap mastic
applied, the second panel run may be started. Prepare the eave
with an inside closure and mastic. Position the panel so that the
overlapping ribs will nest properly. Be sure to check for proper
62
overhang and panel coverage. Stitch the major ribs of the two
panels together and attach panels to the purlins.
Sealing the Eave
Mastic location at the eave is critical. To insure a weather tight
seal, the sidelap mastic must extend down from the top of the rib
to the mastic on the eave closure. The mastic extension must
splice into the eave mastic.
Sealing the endlaps
At the panel endlaps, place a run of mastic across the full panel
width 25 mm below the fastener line. The panel endlaps have a
150 mm minimum overlap located over a purlin as shown or as
per respective erection drawings. Locate the fasteners on the
center of the flange of purlins.
Skylight Installation
One of the simplest methods of getting natural light through a
steel roof is the inclusion of translucent sheets which match the
steel profiles.
It is preferable to use profiled translucent cladding in single
widths so that they can overlap, and be supported by, the steel
cladding on both sides. It is also preferable to position the
lengths of translucent cladding at the top of a roof run so the high
end can lap under the capping or flashing and the low end can
overlap a steel sheet. This is because the translucent cladding
will readily overlap a steel sheet but the reverse is difficult.
Skylight panels are also installed using the same procedures as
a steel panel (Subjected to skylight manufacturers
recommendations). Care should be taken when installing
fasteners in the skylights to avoid cracking the material.
Ridge Installation
Ridge panels are to be installed as each side of the roof is sheet-
ed. This will aid in keeping both sides of the roof aligned. After
having installed a run of panels on each side of the roof, apply
mastic to the panels. Set ridge panel in place and install lap and
purlin fasteners. Apply mastic along the top of the leading rib to
prepare for the next sidelap.

Tape Sealant Application atRidge Flashing
Apply panel sidelap tape sealant as shown for building with ridge
flashing and outside closures. The mastic is placed along the
inside edge of the major rib from the ridge purlin web line to the
upper end of the panel.
Cleaning of Roof Panels
As work proceeds, it is important to keep the roof area clean. A
soft brush or broom should always be readily available to sweep
off drill swarf, metal fillings or grinding dust, which will cause light
surface corrosion if not removed. With a little practice in applica-
tion, squeeze out removal will generally be unnecessary.
However, for practical or aesthetic reasons, uncured sealant can
be removed with a clean, dry rag and any excess then removed
with material turpentine or white spirits.
Excess cured sealant is to be removed with a plastic stapula to
avoid damage to the surface finish. Avoid any unnecessary
smearing of sealant on surfaces intended for painting as silicone
can affect over-paint adhesion. If contamination has occurred,
this may be treated by lightly abrading the area with a non-metal-
lic scouring medium.
64
Pierce-fixing is the method of fixing sheets using fasteners
which pass through the sheet. This is different from the
alternative method called concealed-fixing. The method of fixing
you use is determined by the cladding profile you are using.
You can place screws through the crests or in the valleys,
however, to maximised watertightness, always place roof screws
through the crests. For walling, you may fix through either the
crest or valley.
Always drive the screws perpendicular to the cladding, and in the
centre of the corrugation or rib.
The following procedures are described for roofs, but the same
general principles apply to walls.
General installation procedure
Check flatness, slope and overhang
Before starting work ensure that:
• The supports for your cladding are truly in the same plane
• The minimum roof slopes
• The overhangs of sheets from the top and bottom supports
do not exceed the limit, whilst also overhanging at least
50 mm into gutters
Make any necessary adjustments before you start laying sheets,
because they will be difficult or impossible to rectify later.
Orient sheets before liftingFor maximum weather-tightness, start laying sheets from the
end of the building that will be in the lee of the worst-anticipated
or prevailing weather.
It is much easier and safer to turn sheets on the ground than up
on the roof. Before lifting sheets on to the roof, check that they
are the correct way up and the overlapping side is towards the
edge of the roof from which installation will start.
Place bundles of sheets over or near firm supports, not at mid
span of roof members.
Position first sheet
With particular care, position the first sheet before fixing
to ensure that it is correctly located in relation to other parts
of the building. Check that the sheet:
• Is aligned with the end-wall (or its barge or fascia),
bearing in mind the type of flashing or capping treatment to
be used; and
• Aligns correctly at its ends in relation to the gutter
and ridge (or parapet or transverse wall). Roof sheets should
overhang at least 50 mm into gutters
Fix the sheet as described later in this chapter
Position other sheetsAfter fixing the first sheet in position, align the following
sheets using:
• The long edge of the previous sheet; and
• A measurement from the end of the sheet to the fascia or
purlin at the gutter. It is important that you keep the
gutter-end of all sheets in a straight line
Fix the sheet by either:
• fixing each sheet completely, before laying the next; or
• fix the sheet sufficiently to ensure it can’t move, complete
laying all sheets, then return to place all the intermediate
fasteners later

Check alignment occasionally
Occasionally check that the sheets are still parallel with the first
sheet, by taking two measurements across the width of the fixed
cladding.
At about half way through the job, perform a similar check but
take the measurements from the finishing line to aim for the final
sheet to be parallel with the end of the roof. If the measurements
are not close enough, lay subsequent sheets very slightly out of
parallel to gradually correct the error by:
• properly align and fix a lap, then
• fix the other edge of the sheet, placing the fasteners slightly
closer or further from where they would normally be if there
was no error.
Side-lapping & positioningpierce-fixed sheets
To prevent moisture being drawn into laps by capillary action,
the edges of sheets are slightly modified. CUSTOM ORB® and
custom blue orb have the edges of the sheet over-curved,
other products like SPANDEK®, TRIMDEK® all have flutes
formed into the underlapping rib. It is important that sheets be
lapped correctly.
After fixing the first sheet, place the next (and subsequent)
sheet with its side lap snugly over the previous sheet. Secure the
sheet firmly in place until each end of the sheet has been fixed.
You can do this easily by:
• align the bottom edge accurately by a measurement from the
end of the sheet to the fascia or purlin at the gutter;
• clamp the lap with a pair of vice grips;
• at the top of the sheet: nestle the side lap snugly,
check alignment, and fix the sheet with a fastener.
Pierce-fixing on valleys(for walling only)
Wall fasteners may be placed on the crests, but they are
usually placed in the valley of wall cladding because:
• they are less conspicuous and don’t break the aesthetic
lines of the steel cladding;
• there is no risk of the profile being deformed,
because the fastener is placed through the cladding
where it rests flat against its support; and
• water penetration is not a problem.
However, when valley-fixed, the cladding needs a side-lap
fastener in all laps, at each support. You will find it more
economical in labour, time and cost of fasteners to use a crest

Pierce-fixing on side-lapsWhere roofing and walling are installed according to the support
spacing, side-lap fasteners are generally not required.
You may need to use side-lap fasteners where the cladding is
laid a little out of alignment and the weather resistance of a joint
is questionable. Decide on the number of side-lap fasteners by
what looks effective in each individual case.
Where valley fasteners are used, you need side-lap fasteners
along each lap at each support. Alternatively a crest fastener
may be used at each side-lap, in place of the side-lap fastener
and adjacent valley fastener.
Side-lap fasteners are located in the centre of the crest of the
overlapping corrugation.

Concealed-fixing is the method of fixing sheets using fasteners
which do not pass through the sheet. Instead, the cladding is
held in place with clips. This is different from the alternative
method called pierce-fixing. The method of fixing you use is
determined by the cladding profile you are using.
Concealed-fixing is used for:
• KLIP-LOK™ 700
• KLIP-LOK™ 770
Very steep pitches
To prevent concealed-fixed cladding from sliding downward in
the fixing clips, on very steep pitches, you should pierce-fix
through each sheet under the flashing or capping, along the top
of the sheets.
Installing KLIP-LOK™ roofsUse the same general procedure described in general
installation procedure. However, at the start of installing
KLIP-LOK™ 700 and KLIP-LOK™ 770, a row of clips is fixed to
the supports before the first sheet is located over them and
locked in position.
Clips
For KLIP-LOK™ 700 use KL70 clips
For KLIP-LOK™ 770 use KL77 clips
PreparationAs described in General installation procedure:
• check flatness, slope and overhang;
• orient the sheets before lifting. Note the overlapping rib
is towards the end of the building where you start;
• Check that the overhang of the sheets from the clips,
at both eaves and ridge, is not less than the minimum
Position the first sheetWith particular care, position the first sheet before fixing,
to ensure that it will correctly locate in relation to other parts
of the building. Check that the sheet:
• is aligned with the end-wall (or its barge or fascia),
bearing in mind the type of flashing or capping treatment
to be used; and
• aligns correctly at its ends in relation to the gutter and
ridge (or parapet or transverse wall). Roof sheets should
overhang at least 50 mm into gutters.
Fix the first clips
KLIP-LOK™
Starting method 1. Cut the 1st clip 25 mm from the centre of the
second tower (as shown). The first tower on the cut clip locates
in the 1st rib of the first sheet. This method is preferred because
you don’t have to reach so far to fix the remote end of the clip.
Starting method 2. The first tower on the first clip locates in the
first rib of the first sheet. The clip fixes the edge of the first sheet,
but you must fix two clips at the start, and thus reach out further
for the first and all subsequent sheets.
The following description is for Method 1.
all KLIP-LOK™ profiles
Fix the first clip on the purlin nearest the gutter, with the clip
pointing correctly in the direction of laying. Be sure the clip is 90
degrees to the edge of the sheet.
Using a string line (or the first sheet as a straight edge) to align
the clips as you fix a clip to each purlin working towards the high
end of the roof.

interlocking ribs at regular intervals. It is important that you
don’t walk in the unsupported pan beside the overlap. A
rubber mallet may help engagement of laps on long spans
5. Similarly, engage all the clips by applying vertical foot
pressure to the top of the other ribs over each clip.
It is essential that the sheets interlock completely. It is important
that your weight is fully on the sheet you are installing.
KLIP-LOK™ 700: The spurs on the free edge of the underlap-
ping rib must be fully engaged in the shoulder of the overlapping
rib. You will hear a distinct click as the spurs snap in.
Check alignment occasionally
Occasionally check that the sheets are still parallel with the first
sheet, by taking two measurements across the width of the fixed
cladding.
At about half way through the job, perform a similar check but
take the measurements from the finishing line to aim for the final
sheet to be parallel with the end of the roof. If the measurements
are not close enough, lay subsequent sheets very slightly out of
parallel to gradually correct the error. To allow this to happen,
flatten the tabs on the base of subsequent clips - the slot in the
clip will allow the clips to be fixed out of standard pitch.
Place the last sheetKLIP-LOK™ 700: If the final space is less than the full width
of a sheet, you can cut a sheet along its length and shorten
the clips as appropriate.
Installing KLIP-LOK™ wallsThe installation procedure for walls is similar to that described
for roofs. To engage clips, use a rubber mallet (instead of foot
pressure).
To prevent KLIP-LOK™ from sliding downward in the fixing clips,
you should pierce-fix through each sheet under the flashing or
capping, along the top of the sheets.

This chapter describes how you can treat the ends of sheets to
maximised waterproofing, or to stop vermin entering.
Turn-upsAt the high end of roofing, wind can drive water uphill, under the
flashing or capping, into a building. To minimise this problem,
you turn up the valleys (or pans) at the high end of roofing. The
process is called turning-up (or stop-ending).
All roofing on slopes below 1 in 2 (25°) should be turned-up.
You can turn-up sheets before or after they are fixed on the roof.
If you do the latter, you must have sufficient clearance for the
turn-up tool at the top end of the sheets (about 50 mm).
Turning-up CUSTOM ORB®
With pliers, multi-grips or a shifting spanner closed down
to approximately 2 mm, grip the valley corrugations 20 mm
in from the end of the sheet and turn up as far as possible. Be
careful not to tear the sheet.
Turning-up TRIMDEK® and SPANDEK®
Slide the turn-up tool onto the end of the sheet as far as it will go.
Holding the tool against the end of the sheet, pull the handle to
turn up the tray about 80°.
Turning-up KLIP-LOK™You get the best results by first cutting off the corner of the
down-pointing leg of each female rib. Do this before you place
the sheets on the roof.
• With the hinged turn-up tool open: position the tool on the
sheet with the locating pins hard against the end of the
sheet.
• Hold the handles together to clamp the tool onto the tray, and
pull them to turn-up the tray 90°.
Flush turning-up KLIP-LOK™In normal turning-up of KLIP-LOK™, the tops of the ribs protrude
past the turned up tray. Consequently the turn-ups cannot be
positioned hard against a fascia or wall, or the ends of the sheets
on either side of the ridge cannot be butted together. This is

usually of no consequence because the turn-up is completely
covered by a flashing or capping. However, if you want the ribs
not to protrude past the turn-up, you can make a flush turn-up.
You need an extra 40 mm in sheet length for flush turn-ups.
1. Cut the top of each rib before turning-up the pans. Turn-up
the pans as described before.
2. Position the backing tool in the tray and hold it hard against
the turn-up with a foot.
3. With a rubber mallet, fold the protruding ‘ears’ flush against
the backing tool.
Turning-downAt the low end of roofing, wind or capillary action can cause
water to run back up the underside of the cladding. To minimise
this problem, you turn down the valleys (or pans) at the low end
of roofing. The process is called turning-down (or lipping).
All roofing on slopes below 1 in 5 (10°) must be turned-down.
Turning-down is usually done after the cladding is fixed on the
roof, provided there is no obstruction to the operation of the
turn-down tool.
• Push the turn-down tool over the end of the tray, as far as it will
go.
• Hold the tool hard against the end of the tray and push the
handle to form a turn-down about 20°.
SPANDEK® overlapsWhen SPANDEK® is laid on slopes of 5 degrees or less, cut back
the corner of the under-sheet, at the downhill end of the sheet,
to block capillary action.
Blocking off rib cavitiesDust, insects, birds, rodents and wind-driven rain can enter
a building through the cavities under ribs. To minimise these
problems the cavities can be blocked off. Rib end-stops are
available for KLIP-LOK™; strips of plastic foam can be used for
other profiles.
Infill strips
Closed-cell, foam-plastic infill strips are available to match the
top or bottom profile of our roof cladding.
At the lower end of cladding, the strip is sandwiched under the
roof cladding. Similarly, at the upper end, the strip is sandwiched
between topside of the roofing and the underside of the flashing
or capping.
Don’t use infill strips that can absorb water because retained
moisture can lead to deterioration of the sheet coating. Avoid
using infill strips made from, or treated with, flammable materi-
als, particularly in areas prone to bushfire.

Where roof pitches are below 1 in 5 (10°), you should incorpo-
rate infill strips to maximised waterproofness.
End-lappingBecause our roofing and walling is manufactured by continuous
processes, sheet lengths can be supplied up to the limits of
transport regulations which are frequently long enough to cover
roofs without end-lapping the sheets.
If you contemplate using sheets that are shorter than the full
span, and overlap them, you need to consider:
• the roof slope, because it affects the amount of overlap
• the method of fixing of the cladding to its supports,
because it affects the maximum length of sheet
Fixing methods for end laps
There are three methods of fixing cladding at end laps.
• Pierce-fixed through crests
Position the lap centrally over the support; and the fastening
secures both the lap and the cladding. Space the fasteners as
for an end span (layout in Figure a, terminology and recom-
mended spacing). The thermal expansion is away from the fas-
tener and towards the outer ends of the sheet run.
• Pierce-fixed through valleys
Position the lap centrally on the support, and the fastening
secures both the lap and the cladding. (in Figure b). The thermal
expansion is away from the fastener and towards the outer ends
of the sheet run.
• Concealed-fixed sheets
You can either pierce-fix through the crests or the valleys (in
Figure a and b), or use clips near the lap (in Figure c).
KLIP-LOK™ sheets deform at the clips so that sheets won’t nest
together. If you use clips, the lap is placed just clear of and on
the high side of the clip (in Figure c). The lap is secured with
pierce-fixing through the valleys. The clips allow the sheets to
slip when they expand with heat.
To make the end-lapping of KLIP-LOK™ easier: remove, for the
length of the lap, the down-turn of the underlapping ribs of the
top and bottom sheets in each sheet run. The cut-back ribs are
covered by the sheets of the next sheet run.
longline 305, can be fixed using any of the three methods.
The underlapping ribs have to be slightly squashed at the lap to
allow them to nest. An end-lap tool is available.

Flashings and cappings are strips of metal formed to weather-
proof the edges of roofing and walling. For the purposes of this
chapter, only the term flashing is used.
Similar methods of flashing are used for different cladding-pro-
files. You can adapt the principles to suit your application.
In all cases it is important to have ample cover provided by the
flashing and proper turn-up of the cladding underneath.
Be careful when moving between supports. Do not walk in the
pan immediately adjacent to flashings or translucent sheeting.
Walk at least one pan away.
bluescope lysaght has a range of standard flashings. We can
also supply custom flashings to your requirements - ask your
local service centre for details.
MaterialsIt is very important that flashings be made from materials that are
compatible with the cladding.
Lead flashing is not recommended, however it will usually be
retained when re-roofing, because it is usually cemented into the
structure. In these cases:
• the top surface of the lead flashing must be painted with
a good quality exterior paint system (to limit contamina-
tion with lead compounds in water running off the flash-
ing); and
• there must be a barrier between the lead flashing and
the cladding: either a plastic strip (such as polythene
dampcourse), or paint.
Flashings should conform to AS/NZS 2179.1:1994, and be com-
patible with the cladding.
Materials for non-standard flashings and other accessories are
available in ZINCALUME® steel or COLORBOND® steel finishes.
Longitudinal flashingsLongitudinal flashings run parallel to the pans or valleys, and are
made to suit the sheet profile. They should have an edge turned-
down to dip into the pan or valley.
Transverse flashings Transverse flashings run across the pans or valleys. They
usually have a stiffening bend, along the lower edge, which is
turned-down to dip into the pan or valley. To maximised weather
proofing, the bent edge is fashioned to fit the profile.

The turn-down for transverse flashings for CUSTOM ORB® and
custom blue orb can be either notched, scribed to match the
corrugations, or lightly dressed into the valleys. Scribing or
notching is preferred for low-slope roofs.
The turn-down for transverse flashings for ribbed cladding is
always notched to fit over the ribs, except in the case of
CUSTOM ORB® and custom blue orb where the flashing is
dressed into the valleys.
Notching toolsHand-operated notching tools cut one notch at a time. Each tool
matches only one cladding profile. There are two types of tool;
their use depends on whether or not the edge of the flashing has
first been bent down.
Using notching tools
After the cladding is fixed and the turn-ups finished, proceed
as follows.
• Place a flashing with the notch-edge resting on the ribs.
• Locate your notching tool over a rib with the notching head
against the flashing.
vertical tool: The body locates along the rib.
horizontal tool: the lugs on the underside locates on top
of the rib.
• Raise the handle to open the tool and:
vertical tool: lift the flashing into the mouth of the tool;
horizontal tool: slide the mouth of the tool over the edge
of the flashing as far as it will go.
• Push down on the handle to perform the notching.
• Repeat for all ribs, checking in each case that the flashing is
correctly positioned.
• If you are using a horizontal tool, bend down the tongues
between the notches over a suitable straight edge (such as
a piece of timber).
Notching with tinsnipsIf notching tools are not available, flashings can be notched to
the rib profile with tinsnips. The procedure is sometimes known
as scribing. After the cladding is fixed and the turn-ups finished,
proceed as follows.
• Place the flashing with the turned-down edge resting
on the ribs.
• Mark out the notching using a template positioned over
each rib.
• Cut the notches with tinsnips.
This procedure is also used for hip cappings.
Joining flashings
The overlaps of transverse flashings should be sealed with a
recommended sealant and fastened. Before finally positioning
and fixing the lap, turn over the top piece and apply a 3 mm
bead of sealant across the flashing, about 12 mm from the end.

There are many types of insulation installed in the steel build-
ings. However, fibreglass, rockwool blanket insulation is com-
mon type used, and these instructions pertaining to this type
only. One side of the blanket insulation should have proper bar-
rier that must face the inside of the building regardless of
whether the insulation is for heating or cooling.
Choose correct length, density and thickness of insulation as per
the erection drawing. If require pre cut roof insulation to reach
from eave to eave or eave to purlin allowing approximately 2
feet of additional length to facilitate handling. Hold insulation at
one sidewall and roll out insulation across the purlins, vapour
barrier to the inside of the building. Stretch the insulation to pro-
vide a tight, smooth and wrinkle free side surface. Weight clamp
can be used at each end to hold tight. Double adhesive tape can
be used on eave strut and purlins below the insulation to prevent
insulation from flying off due to wind. Trim excess insulation at
the edge of eave and cut fibreglass approximately 100 mm from
end leaving only facing. Fold facing over end of blanket insula-
tion to seal the ends.
After installing the first roll of insulation, fix the closure on to the
eave strut with the help of double adhesive tape. Install the first
roof panel, before installing the fasteners check the alignment of
roof panel and projection of roof panels beyond eave strut and at
gable end. After installing the first run of roof cladding, lay the
second run of insulation in same manner given above and sta-
ple the side lap by folding as shown in the figure The general
sequence is to install the roof cladding in conjunction with the
insulation.
It is recommended that both sides of the ridge of a building be
insulated and sheeted simultaneously.This will keep the insula-
tion covered for the maximum amount of time and panel ribs can
be kept in proper alignment for ridge cap.
At the sky light portion insulation is cut keeping 150 mm projec-
tion on all side as shown in figure. Cut fibre glass leaving only
facing. Facing to be properly folded and on all sides. If insulation
termination angle is provided the insulation is properly folded
and screwed to the angle.
The insulation blankets 6 inch and thicker require longer screws
(1_ or 1_ in) than commonly used for roofing attachment, to
avoid squeezing the insulation so tight that the panel gets dim-
pled.
14Insulation
76
Insulation cutting at the FRP Sheet
Wall Insulation
The first run of insulation is temporally attach to the eave strut or
support angle with the help of vice grips or other clamping
arrangements as shown in figure. Install double face tape at the
eave strut to hold the insulation. Obtain smooth wrinkle free
inside surface by pulling the insulation tight from top to bottom.
Use double face tape to hold the insulation to the base angle or
bottom girt. Cut the fibreglass from vapour barrier on excess
length and fold up to seal the ends.
The general practice is to install the wall panel in sequence with
the insulation. It is extremely important to check plumb and level
of wall panel before installing. Similarly second run of insulation
is installed side laps are to be properly folded and stapled. There
must not be any holes in the facing.
Sealing Insulation laps
Double tab insulation is sealed together at the sidelaps by fold-
ing and stapling as shown below. The stapling is done from the
outside as the insulation is applied. Pull the adjoining tabs out-
ward at the joint and align the edges. Staple, fold and staple as
shown.

Storage of Insulation Roll
When the rolls of insulation are received they should be careful-
ly stored, protected from the weather. Handle the rolls with care
to avoid damaging or punctur-
ing the insulation facing. Do
not store the rolls which are
multiples of the wall height and
are to be filed cut to required
length.

SafetyIt is commonsense to work safely, protecting yourself and work-
mates from accidents on the site. Safety includes the practices
you use; as well as personal protection of eyes and skin from
sunburn, and hearing from noise.
Occupational health and safety laws enforce safe working con-
ditions in most locations. Laws in every state require you to have
fall protection which includes safety mesh, personal harnesses
and perimeter guardrails. We recommend that you aquatint your-
self with all local codes of safe practice and you adhere strictly
to all laws that apply to your site.
Care and storage before installationRain or condensation is easily drawn between the surfaces of
stacked sheets by capillary action, or they can be driven in by
wind. This trapped moisture cannot evaporate easily, so it can
cause deterioration of the coating which may lead to reduced
life-expectancy or poor appearance.
If materials are not required for immediate use, stack them neat-
ly and clear of the ground. If left in the open, protect them with
waterproof covers.
If stacked or bundled product becomes wet, separate it without
delay, wipe it with a clean cloth and stack it to dry thoroughly.
The sheeting material shoud be placed with a minimum 50 slope
to avoid a water pond.
Handling cladding on siteOn large building projects you can reduce handling time by lift-
ing bundles with a crane direct from the delivery truck onto the
roof frame. Use a spreader bar for long sheets. For small to
medium size projects, without mechanical handling facilities, you
can unload sheets by hand and pass them up to the roof one
at a time.
For personal safety, and to protect the surface finish, wear clean
dry gloves. Don’t slide sheets over rough surfaces or over each
other. Always carry tools, don’t drag them.
Walking on roofsIt is important that you walk on roofing carefully, to avoid
damage to either the roofing or yourself.
Generally, keep your weight evenly distributed over
the soles of both feet to avoid concentrating your weight on
either heels or toes. Always wear smooth soft-soled shoes; avoid
ribbed soles that pick up and hold small stones, swarf and other
objects.
When you walk parallel to the ribs:
• for ribbed roofing walk on at least two ribs or
corrugations (CUSTOM ORB®, and SPANDEK®);
• for pan-type roofing walk in the pans (KLIP-LOK™,
TRIMDEK®).
When you walk across the ribs, walk over or close to the roofing
supports.
15General care, safety andhandling
78
Where possible do not leaveuncovered stacks of sheets lying
in the open.
If stacks cannot be kept under cover,barricade the stack and cover it with
a waterproof tarpaulin, but leavespace between the cover and the
sheets to allow air to circulate.
Store off the ground and on a slopeso that if rain should
penetrate the covering,water will drain away.
Inspect the storage site regularlyto ensure that moisture has not
penetrated the stock.
Be careful when moving between supports. Do not walk in the
pan immediately adjacent to flashings or translucent sheeting.
Walk at least one pan away.
Always take particular care when walking on wet or newly laid
sheets - particularly on steeply pitched roofs.
If there will be heavy foot traffic on a roof, provide a temporary
walkway or working platform to minimise damage.
Never step on the Skylight panel or translucent panel.
Marking out, cutting and drilling
Marking outA pencil of any colour may be used except black or so-called
lead pencils. Don’t use black pencils to mark roofing or walling
because the graphite content can create an electric cell when
wet and thus cause deterioration of the finish. You can also use
a string line with chalk dust, or a fine, felt-tipped marker.
Cutting
Where possible, you should minimise site-work by using sheets
cut to length in the factory.
For cutting thin metal on
site, we recommend that
you use a power saw with
a metal-cutting blade
because it produces
fewer damaging hot
metal particles and leaves less resultant burr than does a car-
borundum disc.
Cut materials over the ground and not over other materials
where hot particles can fall and cause damage to finishes -
especially COLORBOND® steel prepainted finishes. It is best to
have the exterior colour finish of a COLORBOND® prepainted
sheet facing down, however you must then protect the paint fin-
ish from scratching by your work supports.
If you have to cut materials near sheets already installed, mask
them or direct the stream of hot particles away.
Reciprocating nibblers are also widely used in the roofing trade,
and they produce an excellent cut. The resulting small, sharp
scraps can rust and damage finishes; and they can cause per-
sonal injury. Take special care to collect these scraps.
Making holes
Holes are often made by drilling or cutting by hole saw or jig saw.
Mask the area around the hole to protect paint from damage by
swarf.
Clean upSwarf (metal scraps or or abrasive particles resulting from cut-
ting and drilling) left on the surfaces of materials will cause rust
stains which can lead to reduced life of the material.
• Sweep or hose all metallic swarf and other debris from roof
areas and gutters at the end of each day and at the comple-
tion of the installation.
• If swarf has become stuck on a finish, it can be removed.
Take great care not to remove the paint or the metal coat-
ings.
• For critical applications inspect the job two weeks after com-
pletion, when rain or condensation will have caused any
remaining swarf to rust, and thus highlight affected areas.
Warn other contractorsMany stains arising from swarf do so, not from the work of roof-
ing-installers, but from other contractors working on the job.
Similarly, problems can arise from contact with incompatible
materials, like copper piping or chemically treated timber. Acid
cleaning of bricks can also be a problem. Architects and builders
need to be aware of this, and warn contractors accordingly.

SealantsRecommended sealantsNeutral-cure silicone sealants have been successfully used with
the range of steel finishes on our roofing and walling; and on
flashings, cappings, and gutters made from the same materials
as the cladding.
Neutral-cure silicone sealants:
• have good adhesion to the clean surface of all our roofing
and walling;
• are water resistant and non-corrosive;
• are resistant to extreme of heat and cold while retaining
good flexibility;
• provide high resistance to ultra-violet rays (sunlight); and
• have a long service life.
It is important that only neutral-cure silicone be used with sheet
steel. Other silicone sealants, often have a vinegar or ammonia
smell, and give off aggressive by-products during curing which
are detrimental to sheet steel.
If in doubt, look for a message on the sealant package like:
Suitable for use with galvanised and ZINCALUME® steel products.
Cleaning surfaces
For effective bonding, all surfaces must be clean, dry and free
from contaminants such as old sealant or oil.
Mineral turpentine is suitable for cleaning the surfaces but care
must be taken to completely remove all residual solvent with a
clean dry cloth. White spirits is an alternative.
Sealant must be applied on the same day as the surface is
cleaned.
Joint strength
Seams sealed with sealant should be mechanically fixed for
strength. Fasteners in joints should generally be no further apart
than 50 mm.
The sealant does not require significant adhesive strength in
itself, but it must bond positively to all the surfaces it is to seal.
To ensure complete sealant cure, the width of sealant in a lap
should not exceed 25 mm when compressed.
Applying sealant
Always apply the bead of sealant in a continuous line along the
centreline of the fastener holes. This ensures that, when com-
pressed, the sealant positively seals the fastener.
Be careful not to entrap air when applying sealant. Especially,
don’t place a ring of sealant around fastener holes because
entrapped air compresses during tightening of fasteners, and
may blow a channel through the sealant, which could prevent the
fastener from being sealed.
Fasteners
Use solid or sealed fasteners, otherwise you have to apply
sealant to the hollow centre of open blind rivets.
To preserve the life of your cladding, is very important that
fastener materials are compatible with the cladding.
ProcedureThe preferred procedure for lap fabrication is:
1. Assemble, clamp and drill;
2. Separate components and remove drilling debris;
3. Clean joint surfaces as recommended above;
4. Apply bead(s) of sealant;
5. Relocate components and fix;
6. Externally seal each fastener if hollow blind rivets are used.
To prevent premature curing (which causes poor bonding), finish
the joint as soon as practical after applying the beads of sealant.
The manufacturer’s specified sealant open times should be fol-
lowed.

Typical joints with sealant
Sealant 25 mm max.

Sealant 25 mm max.
With practice you will be able to judge the size of beads thus
avoiding squeeze-out and the subsequent need to clean up.
Uncured sealant can be removed with a clean, dry rag and any
excess then removed with a cloth lightly dampened with mineral
turpentine or white spirits. Excess cured sealant is best removed
with a plastic spatula to avoid damage to the surface finish of
the metal.
Avoid any unnecessary smearing of sealant on
surfaces intended for painting as silicone can affect adhesion of
paint. Smeared sealant may be treated by lightly abrading the
area with a non-metallic scouring medium.
Maintenance
Factors that most affect the long life of a roof (or wall) are
original design, the environment of the installation, and the
maintenance of the installation. Maintenance is probably the
biggest factor.
Maintenance includes:
• Regular inspection for problems before they become major
corrosion sites;
• Regular washing down, especially near coastal or industrial
influences;
• Removal of leaves and other debris from gutters;
• Keep walls free of soil, concrete and debris near
the ground;
• Don’t overspray pesticide.
Maintenance of COLORBOND® steel
The paint system on COLORBOND® steel sheet is very durable.
Simple maintenance of the finish enhances its life and maintains
attractiveness for longer periods.
Where the paint finish is naturally washed by rainwater (roofs, for
example) there is usually no additional maintenance needed.
However areas to be washed include soffits, wall cladding under
eaves, garage doors, and the underside of eave gutters.
Washing should be done at least every six months and more
frequently in coastal areas where sea spray is prevalent, and in
areas where high levels of industrial fallout occur. Avoid
accumulation of salty deposits or industrial dirt.
Establish a regular routine for washing COLORBOND®
steel products. Often garage doors can be washed with clean
water at the same time as your car is being washed. Guttering
and eaves can be hosed down when windows are being
cleaned. Walls can be hosed down while watering the garden.
Where regular maintenance doesn’t remove all the dirt, wash the
surface with a mild solution of pure soap or non-abrasive non-
ionic kitchen detergent in warm water. Use a sponge, soft cloth
or soft bristle nylon brush; be gentle to prevent shiny spots.
Thoroughly rinse off the detergent with clean water.
Never use abrasive or solvent cleaners (like turps, petrol,
kerosene and paint thinners) on COLORBOND® steel surfaces.
For advice on grease, oil or deposits not removed by soap or
detergent contact our Information Service
A preventive maintenance program is a key factor in maximising
the life expectancy and dependability of the roof system. It is
important to carryout periodic maintenance of your building to
ensure trouble free service and extend the life span of the
building. As a part of on-going maintenance program, periodic
inspections, beginning at the completion of building are of
utmost importance.

Material Shortage Claim
Short materials: Immediately upon delivery of material, quanti-
ties should be verified against those mentioned in the packing
list. Also the material controller has to check for any damage of
material.
There are different reasons for material shortage at site and
claims can be raised on the appropriate grounds. Mentioned
below are common reasons for claims.
A. Items Not Received
1. Any material mentioned in the packing list but not received
at site due to lost during the transportation.
2. Any material mentioned in packing list but not loaded in
the vehicle.
3. Material required on site has been loaded to some other
site and some other material of other job not appearing in the
shipper list is loaded in the vehicle.
B. Damaged Materials
1. Material damaged in transportation and unloading, which
cannot be rectified at site.
C. Detailing Error
1. Material mentioned in the drawing but not listed in the
shipper list.
2. There could be surplus or shortage in any item due to an
error in preparing the shipper.

A preventive maintenance program is a key factor in maximizing
the life expectancy and dependability of the roof system. It is
important to carryout periodic maintenance of your building to
ensure trouble free service and extend the life span of the
building. As a part of on-going maintenance program, periodic
inspections, beginning at the completion of building are of
utmost importance.
Safety
Whenever you perform maintenance on the roof system, safety
must be a prime concern. Building maintenance personnel
should have fall protection and other personnel protection
equipments. Failure to follow can result in serious personal injury
or even death of the maintenance personnel.
A completed roof system is a safe working surface except near
the edge of the roof and when any moisture (such as dew, frost,
snow etc.) makes the surface of the roof very slippery. Roof
installations with steep slopes can also be hazardous without
proper safety equipment. Appropriate safety measures and extra
caution should be exercised whenever these conditions are
present.
Make sure maintenance personnel are adequately instructed in
safety and that they are provided with appropriate safety equip-
ment. Working off the ground, even a few feet, can be danger-
ous and fall from any height can be fatal.
Whenever performing building maintenance, the following pre-
cautions must be taken:
• Always use fall protection, especially near building edges or
eaves.
• Do not walk on FRP sheets or translucent panels.
• Do not walk on wet roof panels.
• Do not walk, step or sit on skylights or ridge cap.
• Do not walk in gutters.
• Guard all skylights and other roof openings or holes.
Following are general maintenance recommendations for pre-
engineered steel buildings. We suggest that you develop a pre-
ventive maintenance schedule for your buildings based on the
guidelines given below and considering any special conditions
that are specific to your project.
A. Maintenance of Building ExteriorPeriodic maintenance of the exterior will depend on the location
of your building.
Building Location Maintenance Period
1. Upto 5 miles from the sea - 3 months
2. High pollution industrial area - 3 months
3. Medium pollution industrial area - 6 months
4. Areas of high humidity - 6 months
5. Low pollution industrial area - 9 months
6. Dry desert areas - 12 months
Preventive maintenance should commence immediately after a
project is erected, modified or repaired.
1. Check for any debris that may have been left on top of panel
or trim. Example of this are ferrous items such as screws, pop
rivets nails, sheet metal off-cuts, tin cans, etc. large or heavy
items should be removed by hand to avoid damaging the paint
or zinc layer on the panel. The remaining smaller items may be
swept-off with a soft nylon brush. Please note this check should
be made after any tradesman has worked on the building e.g.
electricians, plumbers, air conditioning technicians and steel
erectors.
2. Check for sand or dirt build up. These retain salt and mois-
ture and will rapidly break down the paint and zinc layers result-
ing in corrosion of the base metal.
3. The most vulnerable areas of building are:
a. Gutters
b. Roof sheets
c. Shelters areas under eaves or canopies
d. Top portion of walls sheltered by roof overhangs or
18Building Maintenance and Recommendations
92
gutters sand and dirt should be washed off with clean water
and a soft nylon brush. Clean from top to bottom and give
a final rinse with water when completed. Ensure no water
is trapped anywhere.
4. If building is in an area of high industrial pollution or close to
marine environment then water alone may not be enough. Salt
and other deposits build up at formed corners of panels and
quickly breakdown the paint and zinc layers and finally corrode
the base metal. As such deposits build up, the hardness of the
layers increases making removal more difficult. In these cases
the period between maintenance operations should be short-
ened and a mild detergent should be added to the initial wash-
ing water.
Gutter MaintenanceTwigs, dust, leaves and fungal matter (debris) should be
removed using the following recommended procedure, taking
care to ensure no damage occurs to the gutter during debris
removal. We recommend that the following procedure be adopt-
ed to remove the dust, debris and fungal matter.
• Sweep debris into a pile using a stiff, soft bristled brush
(shovels or hand tools should not be used).
• Place debris into a receptacle and lower to the ground.
• The whole roof and gutter should then be washed down with
a hose, including high ends of gutters possibly protected by
overhangs, rain heads, water spouts and overflow locations.
• If significant fungal growth is found it should be identified and removed.
• Any metallic staining should be investigated to determine
whether the cause is from a metallic deposit on the surface,
or from the breakdown of the coating. Metallic deposits on
the surface should be completely removed immediately.
Breakdowns in the coating would generally result from poor
maintenance techniques and scratching.
Downtake Pipe Maintenance
The downtake pipes and stormwater disposal pipes are to be
inspected for cleanliness and free flow of water. Growth of fun-
gus and other matter and collected debris at the inlet and outlet
locations is to be noted. Complete testing of the system for
blockage at each downpipe is recommended. Record and docu-
ment the observations of the inspections.
• Downpipes made from BlueScope Steel products should be
cleaned using a pressure water hose directed down each of
the downpipes.
• The hose should then be fed into the pipe from the inlet down
to the outlet, to ensure there are no obstructions.
• Constrictions in the downpipe system may make it necessary
to access the pipe from inspection points downstream of the
downpipe inlet location.
• Any noted blockages should be removed immediately, to
avoid water back-up in the gutters.
Penetrations, Flashings, Cappings
All penetrations and cappings are to be inspected for the build-
up of debris or organic material located between the flashings or
cappings and the cladding materials, visually noted to be pro-
truding from, or staining the joint. Care is to be taken in noting
any staining at the high side of penetrations. All observations are
to be recorded and documented in accordance.
• Build-up of debris or organic matter (debris) should be
completely removed using a stiff bristled soft brush. No hard
tools should be used.

• The area should then be washed down with a pressure hose.
Care should be taken to ensure that debris is not lodged
between sheets or the sheeting and flashing and that water
from the pressure hose is not driven into the building.
• Stubborn stains and dirt not removed in the hosing can be
removed by application of soaps and detergents which are
detailed in this document.
Roof Sheeting Maintenance
All cladding are to be inspected for the deposition of any debris,
dust, pollutants or organic growth. In particular, care is to be
taken in the inspection of cladding for these points:
• Staining of cladding at possible ponding locations
• Build up of dust and debris
• Metallic staining of the gutter, surface rust
• Record and document the observations of the inspections.
Maintenance
Twigs, dust, leaves and fungal matter (debris) should be
removed using the following recommended procedure, taking
care to ensure no damage occurs to the cladding during debris
removal. We recommend that the following procedure be adopt-
ed to remove the dust, debris and fungal matter.
• Sweep debris into a pile using a stiff, soft bristled brush
(shovels or hard tools should not be used).
• Place debris into a receptacle and lower to the ground.
• The whole roof and gutter should then be washed down with
a hose, including high ends of gutters possibly protected by
overhangs, rain heads, water spouts and overflow locations.
• If significant fungal growth is found it should be identified and
removed.
• Investigate metallic staining of the roof or gutter to determine
if it is caused by a metallic deposit, or by breakdown of the
coating on the cladding. If it is a metallic deposit, completely
remove it immediately.
Breakdowns in coating would generally result from poor mainte-
nance techniques and scratching.
The following is suggested solution
a. 1/3 cup detergent (e.g. tide)
b. 1/3 tri-sodium phosphate(eg soilex)
c. 1 quart sodium hypochlorite-5% solution (e.g.chlorox)
d. 3 quarts water.
Wash down the panel with the above solution and soft nylon
brush. A final rinse with clean water should follow.
Caulking compounds, oil grease, tar wax or similar substances
can be removed with mineral spirit. Follow this by cleaning with
detergent solution and clean water rinse.
AVOID SOLVENT AND ABRASSIVE TYPE CLEANERS AS
THEY CAN DO MORE HARM THAN GOOD BY WEARING
AWAY BOTH THE PAINT AND ZINC LAYERS
5. Check the base of wall panels to ensure the ground level is at
least 11/2” below the bottom of panels. If wind blown soil has
built up at the base of the wall, it should be removed. If
plants/shrubs etc. are around the building, make sure they are
not touching the wall panels, particularly thorn-type bushes.
6. Check all equipment which is located through or adjacent to
any panel (Roof or Wall). Ensure there is no moisture build up on
or near the panel; if there is, then corrosion is inevitable. If this
condition exits, then modifications are required to avoid it.
The following situations are examples of conditions to be avoided.
a. Water run-off from water services or air conditioners.
b. Copper pipes fastened directly to the steel panel.
c. Open water storage tanks or ponds adjacent to the
panels.
7. Standard gutter and valley gutters:
a. Regular checks should be made and all rubbish and
sand should be removed.
b. Flush the gutters with water.
c. Check the downspouts are clear.
d. Check the downspouts have adequate drainage away
from the building.
8. If minor damage occurs to the sheeting or trims and paint
94
touch is required, then the following procedure should be fol-
lowed:
a. Abrade the effected area.
b. Clean down with a solvent (e.g. sigma 9053)
c. If base metal is exposed, apply one coat of zinc chromate
primer. If base metal is not exposed, then primer is not
required.
d. Apply one coat touch up paint available from BlueScope
steel.
B.Maintenance of Accessories
Personal Doors
a. Occasionally lubricate the hinges and locksets.
b. Remove any dirt or grit from the threshold.
c. Make sure the door is not allowed to swing back against
the wall; this can spring the hinges, and damage the
panels.
Sliding Doors
Regular cleaning of bottom door guide by removal of stones and
sand will ensure smooth running.
Roll Up Doors
a. Occasionally clean and lubricate and chain and reduction
drive gears
b. Lightly grease the vertical guides
Power Vents
Periodically clean the blades to avoid build-up of dust and dirt.
Check electrical connections and check tightness of all
fasteners.
Building with Cranes
a. Every three months, check the diagonal rod bracings are
tight.
b. After one month of operation, check the high strength
bolts on crane beams are tight. Also, this check is to be
carried out every 3 months subsequently.
c. Crane rails checking to be done every 3 months for the
weldments.
d. End stoppers to be checked once every 3 months.
C.Safety PrecautionsRoofs
Extreme caution should be exercised when working on roofs:
a. Only use ladders which are long enough to reach one
meter above the step off.
b. Always secure the ladder to the building and make sure it
is on a firm base.
c. Do not step on a skylight panels.
d. When walking on the roof, step on low corrugations,
walking on high corrugation can damage the sheets. Walk
on screw line wherever possible.
Overhead Cranes
a. When maintaining overhead or associated parts, lockout
the electricals on the crane before commencing work.
b. After the days work, the overload crane should be placed
always between the two rafters / truss i.e. never below a
rafter or a truss.
c. Whenever the building is close to any road curve / access
curve, “Ballard Foundation” should be provided to avoid
vehicle striking the building
