    Steel structures of buildings

    Steel structures of buildings are buildings composed of steel materials. The structure is mainly steel frames, steel trusses, grids, etc., made of section steel and steel plates, and uses physical rust removal and spray paint or galvanization. Bolted connections or on-site welding are usually used between components or parts. Because of its lightweight and quick and convenient construction, it is widely used in large-scale workshops, logistics warehouses, high-rise buildings and other fields.
