PRE ENGINEEREDSTEEL BUILDINGS
Concept , Design &
Construction
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.
Steel was very expensive item in USA The concept of PEB originate from here. The idea was that section should be provided as
per Bending Moment Diagram. This lead to the saving in steel and development
of PEB concept.

Self weight 30% lighter Erection process is
easy, fast, step by step
Overall price -30%lower
architecture-achieved at low cast
Self weight More heavy Erection process is
slow and extensive field labor is required.
Overall price - Higher Price per square meter.
Architecture- achieved at higher cost
Foundation-simple design, easy to construct & light wt.
Erection cost and time- accurately known
Seismic Resistance- low weight flexible frames offer higher resistance to seismic forces
Foundation- expensive, heavy foundation required.
Erection cost and time- 20% more than PEB
Seismic Resistance- rigid heavy weight structures do not perform well in seismic zones
