Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, columns, trusses and other components made of section steel and steel plates, and adopts rust and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts, or rivets are usually used to connect various components or components. Due to its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rusting, and generally require rust removal, galvanizing, or coating, as well as regular maintenance.
