[0002] Steel structure is a structure made of steel materials. It 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 steel sections and steel plates. It adopts silanization, pure manganese phosphating, anti-rust paint, water washing and drying, galvanizing, shot blasting and other rust removal and anti-rust processes. The components or parts are usually connected by welds, bolts or rivets.
