Structural steel is used to make roof structure. The procedure of making steel roof structure is quite complicated. The steel is cut, welded and assembled and painted at a work site. Fortunately, with advance technology, high tensile strength rust proof steel was developed and used to make prefabricated roof structure. The structure is designed and produced from the factory and the members of the structure are brought to assemble with nut and screw system at the work site. This can reduce the time used for cutting and welding and the rusting can be prevented.

Roof structure should be beautiful and strong enough to support roofing materials for the safety of the dwellers.
