Pre-engineered buildings (PEBs) are constructed using prefabricated steel sections designed based on structural calculations. The sections are manufactured in a factory, transported to the site, and assembled using bolted connections. PEBs originated in the US due to high steel costs, as using prefabricated sections reduced steel usage. PEBs offer benefits like faster construction, lower costs, seismic resistance, and large clear spans, and are used for industrial, commercial, and infrastructure projects.

 The buildings are design as per
client’s requirement & actual
design calculations using tapered
sections.
 A combination of built up section,
hot rolled section, cold formed
elements and profiled sheets
 Designing and casting is done in
factory
 Building components are brought
to site
 Then fixed/jointed at the site
 All connections are bolted.
