Pre Engineered Buildings (PEB) are the buildings which are engineered at a factory and assembled at site. Usually PEBs are steel structures. Built-up sections are fabricated at the factory to exact size, transported to site and assembled at site with bolted connections. This type of Structural Concept is generally used to build Industrial Buildings, Metro Stations, Warehouses etc.

The adoptability of PEB in the place of Conventional Steel Building design concept resulted in many advantages, including economy & easier fabrication. These type of building structure can be finished internally to serve any functions that is actually help in low rise building design. Examples of Pre-Engineered Buildings are Warehouses, Canopies, Factories, Bridges etc.

Components of PEB:

Pre Engineered Buildings consist different steel structural members which are as followings,

Primary Frame: Primary framing of a PEB is an assembly of builtup H-Shaped steel members & that framing consist trusses or castellated beams etc.

Secondary Structural Elements: It is actually Cold Formed Members, which can be in different shapes like “Z”, “C” etc. In general known as “Purlins”.

Roof & Wall Panels: Roof Tiles & Curtain Wall made of Glass & Roll-formed currugated steel sheets usually comes in this category.

Sandwich Panels: Insulated composited sandwich panel is made of three layers, in which varied core materials is inserted to two steel sheets.

Other Accessories: Mezzanine floors, Bolts, Insulation, etc.

Advantages of PEB:

There are many advantages of Pre Engineered Buildings, which are as followings,

1.Quality control is the main advantage as all the structural member are engineered beforehand, standards of different codes also taken into consideration & these components are made in factory under the supervision of Quality Control Engineer.

2.Lower cost due to the saving in design, manufacturing and on site erection cost.

3.Minimizing time of construction due to the use of software for design of the structural components.

4.Low Maintenance due to use of standard quality of paints over steel members , which increases the ability to withstand & finally the maintenance cost will be low as compare to conventional steel building.

5.Quick Erection, as all the members are Pre Manufactured & skilled labor is used for connections of different components.

6.Warranty on PEB, mostly warranty period of 20 years given by manufactures for PEB.
