4. PRE ENGINEERED BUILDINGSPRE ENGINEERED BUILDINGS
Tailor made building based on
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.
