A steel building is a metal structure fabricated with steel for the internal support and for exterior cladding, as opposed to steel framed buildings which generally use other materials for floors, walls, and external envelope. Steel buildings are used for a variety of purposes including storage, work spaces and living accommodation. They are classified into specific types depending on how they are used. Developed from standard grade high strength welded stainless steel, the Pre Fabricated shed acts as a durable structure for a supermarket or for factory warehouse. The entire structure of this type of building is featured with hot-dip galvanization treatment. Easy to erect, this type of building consists of mezzanine flooring, C section or Z section purlin, aluminum alloy or PVC made a window, durable welded column and sandwich panels for insulation purpose. Acknowledged for its earthquake resistance properties, good ductility, structural stability, high density and weather proof design, this type of building is suitable for extending its height or available space.
