Pre Engineered Buildings (PEB) are the buildings that are engineered at a factory and assembled at the site.
PEBs are steel structures. Built-up sections are fabricated at the factory to the exact size, transported to the site, and assembled at the site with bolted connections.
This type of Structural Concept is generally used to build Industrial Buildings, Metro Stations, Warehouses, etc.
Components of PEB:
Primary Frame: Primary framing of a PEB is an assembly of built-up I-shaped steel members & that framing consist of trusses or castellated beams etc.
Secondary Structural Elements: It is actually Cold-Formed Members, which can be in diff. shapes like “Z”, “C” etc. In general known as “Purlins”.
Roof & Wall Panels: Tin shades & Curtain Wall made of Glass & Roll-formed steel sheets usually comes in this category, S
Sandwich Panels: Sandwich Panel is made of three layers, in which a non-Aluminum Core is inserted b/w two aluminum sheets.
Other Accessories: Mezzanine floors, Bolts, Insulation, etc.
Advantages of PEB:
Quality control
Lower cost
Minimizing time of construction
Low Maintenance
Quick Erection
Disadvantages of PEB:
Rusting / Corrosion Sensitive
Insulation Cost
Appearance
