Pre-engineered buildings are buildings that are built in factories and are made of steel that are shipped to site and bolted together. Pre-Engineered Buildings revolution the construction market using built up sections in place of conventional hot rolled sections. A large column free area is the utmost requirement for any type of industry which is provided by Pre-Engineered Buildings.
Pre-Engineered Buildings concept involves the steel building systems which are pre designed and prefabricated. As the name itself indicates, there is involvement of pre engineering of structural elements. The basis of PEB is to provide the section at the specified location only according to the need at that spot. The sections may differ along the length according to the bending moment diagram. The use of optimal least section leads to the effective saving of steel and also reduction in the cost.
This system involves tapered or parallel columns or tapered beams which are called rafters. Base of column is either fixed or pinned based on the load requirements.
It consists of purlins, grits which are the side claddings and eave struts stiffened by sag rods. This system also includes the flange stiffeners which joins the untied flanges of the PEB primary system to the secondary system.
Rod bracing and the portal system are the two types of wind bracing systems. Each one is chosen accordingly depending on design and functional requirement.
This part includes the Turbo ventilator, ridge vents, Flashings, gutters, down pipes, ladders etc.
Some of the many applications of PEB are:
PEB are more advantageous than the conventional structures in economy, speed of construction and simple erection. As these structures have a wide scope, they must be preferred and utilized.
