Structural Fabrication
Structural fabrication builds welded and bolted steel structures from beams, channels, angles, hollow sections and plate, such as platforms, mezzanines, sheds, frames and support structures, to engineering drawings.
What it is
Sections are cut to length, drilled or punched for bolted connections, fitted up and welded into assemblies, then surface-prepared and painted or galvanised. Large structures are fabricated in transportable modules and bolted together on site.
Accuracy of connection holes and member lengths matters for smooth site erection.
Typical applications
- Platforms, walkways and staircases
- Mezzanine floors and racks
- Equipment support structures
- Sheds and canopies
- Pipe racks and gantries
Suitable materials
- Structural steel (IS 2062 E250/E350)
- Stainless steel
- Aluminium
- Hollow sections and pipes
Points to consider
- Provide fabrication drawings with member sizes, connections and weld details.
- Plan module sizes for transport and site access.
- Specify the paint system or galvanising for the environment.
- Bolt grade and connection type should be clear on drawings.
Frequently asked questions
What sections are used in structural fabrication?
Beams (ISMB), channels (ISMC), angles (ISA), hollow sections, plates and flats, usually in IS 2062 steel.
Can structures be galvanised?
Yes. Hot-dip galvanising gives long corrosion protection; designs need vent and drain holes for galvanising.
Do you fabricate in modules?
Yes. Larger structures are made in bolt-together modules sized for transport and erection.
