Pre engineered building is third generation construction, it adopts H type steel, C type steel and Z type steel to combine or build framework, roof and wall and are color steel compressing corrugated steel or color steel sandwich panel. PEB structure has basically substituted traditional reinforced concrete in developed countries.
Self Engineered Steel Building:
Primary Member is tapered section
Secondary members are lightweight rolled framed “Z” and “C” section
Delivery – average 6 to 8 weeks
Foundation-simple design, easy to construct & light wt.
Erection cost and time- accurately known
Erection process is easy, fast, step by step. Seismic Resistance- low weight flexible frames offer higher resistance to seismic forces
Overall price -30%lower. Architecture achieved at low cost.
Conventional Steel Building:
Primary members are Hot rolled “I” section
Secondary members are “I” or “C” section which are heavy in weight
Delivery- average 20 to 26 weeks
Foundation- expensive, heavy foundation required.
Erection cost and time- 20% more than PEB
Erection process is slow and extensive field labor is required.
Seismic Resistance- rigid heavy weight structures do not perform well in seismic zones
Overall price - Higher Price per square meter.
Architecture- achieved at higher cost
