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
