Introduction
• Pre-Engineered Buildings can be adapted to suit a
wide variety of structural applications.
• All the components are produced in a factory on
basis of structural and aesthetic requirements.
• These components are made in modular (or)
completely Knocked down condition.
Page 3
Introduction
• Manufactured materials are transported and
assembled in the customer site.
• Manufacturing and Production processes like cutting
and welding is not done at the customer site.
• An efficiently designed Pre-Engineered Building can
be lighter that the conventional steel buildings by up
to 30%.

Technical Parameters of PEB
• Breadth, width or span of the building.• Length of the building.• Roof slope.• Design Loads.• Bay spacing.• Type of Frame.• Sub Systems.

Main Components of PEB
•Primary components: Primary components include Columns and Rafters •Secondary Components: Secondary components include Purlins, Grits and Eaves
Page 8
Main Components of PEB
• Sheeting or Cladding: Corrugated or Galvanized sheets are used as sheeting
Page 9
• Accessories: Accessories include Sky lights, Wall lights and Turbo Ventilators.

Advantages of PEB
• Optimised design of steel reducing weight• Architectural Versatility• Light weight• Quick Project completion• Less cumbersome at site• Good Seismic resistance• Easy future expansion
Page 11
Advantages of PEB
• Architectural Versatility• Dismantellable and reusable• Voluminous space (upto 30 m span)• Weather proof• Architectural versatility• Water tight roof and wall coverings
Page 12
Applications
• Industrial Buildings• Ware houses• Air Craft Hangers• Commercial complexes• Offices• School Buildings• Offices• Indoor stadiums
Page 13
• Outdoor stadiums• Gas Stations• Metro stations and Bus terminals• Parking lots• Stadiums• Railway platforms • Cold storages
Applications
Page 16
• Self weight 30% lesser• Primary member is
Tapered section • Secondary members
are light weight rolled framed “Z” and “C” section
• Self weight more heavy• Primary member is Hot
rolled section• Secondary members
are “I” or “C” section which are heavy in weight.

• Delivery – average 6 to 8 weeks
• Foundation-simple design, easy to construct & light wt.
• Erection cost and time- accurately known
• Delivery- average 20 to 26 weeks
• Foundation- expensive, heavy foundation required.
• Erection cost and time- 20% more than PEB

Market Potential
• PEB is relatively a new concept in India and were
introduced to markets lately in 1990’s.
• The market potential of PEB in India is 12 lakh
metric tonne and growing at a compound rate of 25
to 30%.

Conclusion
• PEB concept has been very successful and well established in North America, Australia and is presently expanding in U.K and European countries. PEB buildings provide good insulation effect and would be highly suitable for a tropical country like India.
• The pre-engineered building calls for very fast construction of buildings and with good aesthetic looks and quality construction. Pre-engineered Buildings can be used extensively for construction of industrial and residential buildings.
