What is Pre-engineered Building (PEB)?

Pre Engineered Building (PEB) is steel structural building that is fully fabricated in the factory, shipped in completely knocked down condition, and erected promptly on the building site. These steel buildings are tailor-made as per the client’s specifications and have a lot of flexibility for changes.

PEB is built over a structural concept of primary members, secondary members, and the cover sheeting connected through fasteners. These structural members are custom designed to be lighter in weight as well as high in strength, assuring fast construction. Pre-engineered steel buildings can be fitted with different structural accessories including mezzanine floors, canopies, fascia’s, interior partitions, etc. and the building is made waterproof by use of special mastic beads, filler strips, and trims. This is a very versatile building system and can be finished internally to serve any required function and accessorized externally to achieve attractive and distinctive architectural styles.

Usually, PEBs are steel structures and can be an alternative to conventional structural steel buildings and Reinforced Cement Concrete Buildings. Pre-engineered metal buildings use a combination of Structural steel framing systems, Metal roofing systems, and Wall panels of varying materials. Steel is the material of choice for design because it is inherently ductile and flexible. It flexes under extreme loads rather than crushing and crumbling. Structural steel’s low cost, strength, durability, design flexibility, adaptability, and recyclability continue to make it the material of choice in building construction. Fast construction lowers overhead expenses for construction management services. Steel is extensively used in the construction of industrial buildings of large spans with or without cranes (medium and heavy buildings), where concrete construction is not feasible.

PEBs optimally utilize resources, and leverage technology to the maximum. Pre-engineered buildings have gained a global reputation for durability, water, and earthquake resistance. PEBs are tremendously versatile – they are easy to set-up, expand, modify, and transport to different locations. They are environmentally friendly and can be aesthetically designed with unique features.


PEB structural components are fabricated at the supplier’s factory to exact size, transported to site and assembled at site, usually with bolted connections.

The basic parameters that define a pre-engineered building are:

Building Width is defined as the distance from outside of eave strut of one sidewall to outside of eave strut of the opposite sidewall. This does not include the width of Lean-To buildings or roof extension:

Building Length is longitudinal length of the building measured from out to out of end wall steel lines.

Building Height is the eave height which is the distance from the bottom of the main frame column base plate to the top outer point of the eave strut. When columns are recessed or elevated from finished floor, eave height is the distance from finished floor level to top of eave strut.

Clear height is the distance from the bottom of the main frame column base plate or finished floor level to the inner point of the eave strut at side.

Roof Slope (x/10) is the angle of the roof with respect to the horizontal. The most common roof slopes are 0.5/10 and 1/10. However any practical roof slope is possible.

End bay length is distance from outside of the outer flange of end wall columns to center line of the first interior frame column.

Interior bay length is distance between the center lines of two adjacent interior main frame columns. The most common bay lengths are 6 m, 7.5 m and 9 m.

Design Loads unless otherwise specified PEBs are designed for the following minimum loads:
Roof Live Load: 0.57 kN/m2
Design Wind Speed: 110 km/h

Design for snow loads, earth quake loads, collateral loads, crane loads or any other loading condition, if required must be specified at the time of request for quotation.
