For spans greater than 12 m, it becomes

economical to use steel trusses, as timber as a material for

trusses has become obsolete for various reasons.

Steel is the new-age building material and Steel Buildings

are resistant to moisture, adverse weather conditions like

cyclones, high velocity winds, heavy snow,

Earthquakes, termites and fire.

They are 100% customized using innovative state-of-the art

technology for faster manufacturing and erection.

Buildings can be erected in only 33% of time that it normally takes

to construct a conventional building. They provide you with

lifelong durability, safety and very

low cost-maintenance.

Industrial buildings

Any building structure used by the industry to store raw materials

or for manufacturing products of the industry is known as an

industrial building.

Commercial buildings

A building is that is used for commercial purposes such as offices,

retail, restaurants, hotels, convention centre, clubs, cinema halls

warehouses etc

Institutional buildings

A building intended for persons confined to receive medical,

charitable, or other treatment such as jails and other buildings

like schools, colleges, hostels, courts etc

These can be categorized as Normal type industrial buildings and

special type industrial buildings.

Normal type industrial buildings are simple roof structures on

open frames. These require large and clear floor areas

unobstructed by the columns providing sufficient flexibility.

They are constructed with adequate headroom for the use of an

overhead traveling crane.

Special types industrial buildings are used for manufacture of

heavy machines, production of power etc. Their function dictates

the degree of sophistication required.

Typically the bays in industrial buildings have frames spanning the

width direction. Several such frames are arranged at suitable

spacing to get the required length

Rigid frame consist of two columns and a beam or a girder that are rigidly connected at their joints.

The arrangement and sizes of various members of a steel truss

depends on the span, loading and wind pressure.

Connections usually use transitional elements such as steel angles, tees or plates. The actual connections may be riveted but are more often bolted or welded

Shear connections

Simple frame Shear connections are made to resist only shear and are free to rotate under gravity loads. Shear walls or diagonal bracing is required for lateral stability of the structure

If top of the beam is to be flushed

with top of the girder, the top

flange of beam is cutaway

Semi-Rigid Frame-connections assume

Beam and girder connections possess

a limited but known moment-resisting

Capacity

Movement connections are able to hold

their original angle under loading by

developing a specified resisting moment

usually by means of plates welded or

bolted to the beam flanges

Small opening may be cut or

Drilled in the web, but large

Openings weaken the web in

Shear and require stiffening or

reinforcement

If all components of the structure are fabricated

at a factory and only assembled at the site it is

know as PEB Pre Engineered buildings

Pre engineered steel buildings

Advantages Larger clear spans ranging from 12M and above Larger bay spacing thereby reducing the number of foundations and columns

No welding is required at site and hence it can be erected at sites where electricity is not available.

They are 100% customized using innovative state-of-the art technology for faster manufacturing and erection.

Building can be erected in only 33% of time that it normally takes to construct a conventional building

Ease of constructing multi-deck structures

Pre engineered steel buildings

Advantages They provide you with lifelong durability, safety and very low cost-maintenance.

Better metal roofing and cladding system for aesthetically attractive structures

Special building components like skylights, ridge ventilators, turbo ventilators, sliding doors, windows, roof curbs etc can be supplied and installed.

Dismantable and relocatable These structures can be resold if required and a good percentage of the cost of the structure can be recovered.

Applied loads produce axial, bending, and shear forces in all the members of the frame since the rigid joints restrain the ends of the members from rotating freely.

In addition, vertical loads cause a rigid frame to develop horizontal thrusts at the base.

Various shapes of rigid frames can be fabricated of steel to span from 9 m to 36 m.

Rigid frames typically form one storey structures used for industrial buildings, warehouses and recreational facilities.

Rigid frame construction consists of following

1.Primary framing System

2. Secondary Framing System

3. Cladding

4. Accessories

Primary Framing System

The main frame is the main load carrying members of a structural

system which include columns, end wall posts, rafters and other

main support members.

Secondary Framing System

Structural members are the Purlins, Girts, Eave Struts and diagonal

portal frames bracing. Purlins support the roofing while Girts supports

the side wall cladding.

Purlins and Girts also helps in resisting part of longitudinal forces

generated due to wind or earthquake loads and they provide lateral

bracing to the compression flanges of the main frame members

thereby improving the primary frame capacity.

Secondary Framing System

Roofing and cladding

Metal cladding sheet

Color Coated Galvanized

Roofing and cladding

Skylight

Made of translucent GRP to match rib and wall panels, with an

estimated light transmitting capacity of 60 %.

Accessories

Advantages of Roof Vents : Installation on new or existing roof is a simple process as the metal base can be shaped on site to any roof profile. In case of any difference in thermal and wind pressure, the turbine head and ball bearings help the ventilator to rotate freely providing natural ventilation. It is corrosion resistant giving ruggedness to the structure. The variable pitch throat makes it possible to be fixed at any roof pitch. Its storm proof feature enables rain water to drain through without spilling into turbine

Roof jacks

These are enclosures for pipes or

stacks projecting from the roof.

They allow for safe working on the

roof.

Ridge ventilator

This is a gravity type ventilator

which is provided with a bird

screen and mechanical Controlled

damper. Allows natural ventilation

of the building.

Louvers

They allow fresh air to come inside and prevent the entry of dust

and rain water

Removes dampness and humidity
