Materials
The roofing shall be Klip-Lok 700 profile, roll-formed in continuous lengths in one of thematerials in the table below. Klip-Lok 700 is obtained from Global Roofing Solutions.
The Profile
The profile is roll-formed from certified steel complying with (select from steel column in above table). The profile shall have 4 trapezoidal ribs at 233mm centres giving a nett cover of 700mm. The male rib shall have spurs to ensure a positive double interlocking action at side-laps. Each pan shall incorporatetwo stiffener ribs.
Assembly
It is recommended that Klip-Lok 700sheeting be laid by an approved contractor instrict accordance with the manufacturer’sspecifications. When using a GRS(Brownbuilt) Approved Contractor, a five yearguarantee on site-workmanship and watertightness may be issued after approval by Global Roofing Solutions.
Flashings
Stop endings must be formed at the apexand the pan turned down at the eaves toform a drip. The roof sheeting shall be closedas necessary with purpose-made flashingsof a design approved by the supplier. Theseflashings shall be notched around ribs, wherenecessary, and fixed on S10 clips. All theseoperations must be performed with specialtools available from the supplier.
Site Handling
Klip-Lok 700 sheets should be suitably supported, clear of the ground, under well ventilated cover, away from risk of damage by building operations, contact with cement,dust, lime and abrasive dust, until installation takes place.
Cleaning Up
The complete roof must be kept clean andfree of any swarf and debris.
Quality Assurance
The manufacturer shall be assessed and certified as complying with ISO 9001:2008Quality Management System.
Translucent Sheeting
The Klip-Lok 700 profile is available inPolycarbonate.

Fasteners
The recommended fasteners for fixing the KL 700 &KL 700 Plus clips to steel or timber purlins are as follows:
For Steel PurlinsAt least 3 threads should protrude past the support.
1mm to 4,5mm thickNo.10 - 16 x 16mm long self-drilling Wafer headPH2 screws #3 drill point.
5mm to 12,5mm thickNo.12 - 24 x 38mm long self-drilling Wafer headPH3 screws #5 drill point.
For Timber PurlinsThe screw should penetrate the purlin by the same depth recommened as if there were no insulation.
No.10 - 11 x 45mm long self-drilling Wafer headPH2 screws. Type 17 drill point.
Where insulation is installedBetween purlin and sheeting, the length of screws shouldbe increased, depending on the compressed thickness and density of the insulation. Please refer to the GRS Installation Manual for additional information on insulation fixing details.
*For light steel frame purlins less than 1mm thick, please contact GRS.

NoteFasteners must be selected to match the life expectancy of the roofing and cladding material. The coating class for fasteners, complying with SANS 1273, should be used in conjunction with all roofing and cladding material. For a full range of compatible fasteners, please refer to the GRS Installation Manual.
NoteWhere screws exceed 45mm long, they should be No.12 with a PH3 head.

Sheet Lengths
Klip-Lok 700 is available, ex-factory, in sheetlengths limited only by transport restrictions;normal loads 12.5m and abnormal loads18.6m. Longer lengths can be milled on site,eliminating end laps, which are notrecommended.
End lapping negates the concealed fixconcept and no water tightness guaranteecan be given.
End lapping reduces the life expectancy ofthe roof, due to corrosion.
Bullnosing and Cranking Springing
Klip-Lok 700 can be sprung to a minimum radius of 36m (convex only) with internal span of purlins 1.5m maximum.
Additional Applications
NoteReverse cranking is not possible.
NoteConsideration for road transport has to be taken into account.
Refer to the GRS Installation Manual fordetailed dimensions and fixing instructions.
Site cranking for milled sheets is availableon application.
