The steel prefabricated workshop is new type of building structure, integrating the real estate, construction building and metallurgic industry into a brand new industrial system. That is a reason why so many insiders hold optimistic attitude toward the development of steel building structure in the future.
In comparison with the conventional concrete building, steel plate and sectional steel replace the concrete in the steel structure building which feature high strength and good anti-seismic. Because of components being produced in the factory and installed on site, the time limit will be significantly reduced. Due to reusable property of steel material, the amount of construction waste can be significantly reduced and less environmental pollution, so that this material is widely used worldwide and applied in industrial and civil buildings. Currently, the application of steel structure building in the high rise building and mega high rise building has become increasingly sophisticated and gradually become mainstream building process which is the orientation building industry has developed toward in the future.
The steel structure building is loading carrying building consisting of building steel. Generally speaking, the steel structure consists of components made of sectional steel and steel plate such as beam, column and truss.
Sectional steels used in the building are heat rolled and formed steel angle, box iron, joist steel, H shape steel and steel tube. Load carrying building made of such components is called sectional structure building. In addition, thin wall sectional steel formed by thin steel plate with rolling rim or without rolling rim and small sized steel such as steel angle, reinforcing steel bar form the loading carrying building.
