Pre-engineered Buildings are very ideal for offices, houses, showrooms, warehouses, shop fronts etc. The application of pre-engineered concept is very economical and speedy. These Buildings constructed in short time (i.e. less than half the normal time of traditional construction) when complimented with other engineered sub-systems.
There are nine major components in pre-engineered buildings:
- Main framing or vertical columns
- End wall framing
- Purlins, girts and eave struts
- Sheeting and insulation
- Crane system
- Mezzanine system
- Paints and finishes
Main framing or vertical columns
Main frames include steel rigid frames of the building. The PEB steel rigid frames include tapered columns and tapered rafters. These tapered sections are fabricated using the state of art technology while the flanges are welded. The frame is then erected by bolting the splice plate of connecting section together.
End Wall Framing
The endwall frame of Prefabricated building is designed as a main rigid frame. The beam endwall system of framing consists of columns with pinned ends, supporting horizontal beams as known as endwall rafters.
Purlins, girts and eave struts
Purlins, girts and eave struts are the secondary cold-formed members. No welding is involved in this preparation. They are prepared by just bending the steel coil in order to give it a desired shape (Z-shape for purlins and girts, and C-shape for eave struts).
Sheeting and Insulation
The steel sheets are normally galvanized profile sheets permanently colour coated, plain or sheets can be coated with special paints for better anti-corrosion properties. These buildings are properly insulated through insulation slab/rolls and then the roofing steel sheet is fixed over it.
Crane system in industrial building is used to improve material handling productivity allowing more utilization of space by reducing or eliminating traffic due to forklifts etc. This crane runway beams are supported by built-up sections with cap channels.
The Standard mezzanine framing system consists of steel deck supported by joists framed onto main mezzanine beams. The economy of mezzanine system is affected by the applied loads and mezzanine column spacing.
Paints and finishes
Pre-painted steel is produced on modern, high-speed coil painting lines where surface preparation prior to painting, paint application & paint curing is done on a highly automated line under optimum condition.
