Steel structure is a structure composed of steel, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and zinc plating are adopted. Welding, bolts or rivets are usually used to connect components or parts.
