PRE ENGINEERED BUILDINGS ï

Tailor made building based on client·s requirement & actual design calculations using tapered sections.

ï

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.

BRIEF HISTORY ï Steel was very expensive item in USA ï The concept of PEB originate from here. ï The idea was that section should be provided as per

Bending Moment Diagram. ï This lead to the saving in steel and development of PEB concept.

ï Aesthetic Appeal ï Faster Completion ï Economical ï Seismic Resistance ï Ease of Expansion ï Maintenance Free ï Large Clear Spans ï Controlled Quality

ï Self weight ï 30% lighter ï Erection process is

easy, fast, step by step ï Overall price 30%lower ï architecture-achieved at low cast

ï Self weight ï More heavy ï Erection process is

slow and extensive field labor is required. ï Overall price - Higher Price per square meter. ï Architecture- achieved at higher cost

ï Foundation-simple

ï Foundation- expensive,

design, easy to construct & light wt. ï Erection cost and timeaccurately known ï Seismic Resistance- low weight flexible frames offer higher resistance to seismic forces

heavy foundation required. ï Erection cost and time20% more than PEB ï Seismic Resistance- rigid heavy weight structures do not perform well in seismic zones
