Pre Engineered Steel Building (PEB) Fabrication & Supplier Company in Dhaka, Bangladesh.

Pre-engineered buildings are factory-built buildings of steel that are shipped to site and bolted together. What distinguishes them from other buildings is that the contractor also designs the building - a practice called design & build.

This style of construction is ideally suited to industrial buildings and warehouses; it is cheap, very fast to erect, and can also be dismantled and moved to another site - more on that later. These structures are sometimes called 'metal boxes' or 'tin sheds' by laymen - they are essentially rectangular boxes enclosed in a skin of corrugated metal sheeting.

Steel structural systems of pre-engineered building

The structural system of pre-engineered steel buildings give it its speed and flexibility. This system consists of factory-fabricated and factory-painted steel column and beam segments that are simply bolted together at site. The columns and beams are custom-fabricated I-section members that have an end plate with holes for bolting at both ends.

These are made by cutting steel plates of the desired thickness, and welding them together to make I sections. The cutting and welding is done by industrial robots for speed and accuracy; operators will simply feed a CAD drawing of the beams into the machines, and they do the rest. This production line style of work makes for great speed and consistency in fabrication. The shape of the beams can be tailored to optimum structural efficiency: they are deeper where the forces are greater, and shallow where they are not.

Pre-engineered Steel structures have the following advantages:
