The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and is treated with rust removal and anti-rust processes such as silane treatment, pure manganese phosphating, water washing and drying, and galvanization. Usually, the components or parts are connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, venues and super high-rise buildings. Steel structures are prone to rust. Generally, steel structures need rust removal, galvanization or coating, and regular maintenance.

结构主要由型钢和钢板等制成的钢梁、钢柱、钢桁架等构件组成，并采用硅烷化、纯锰磷化、水洗烘干、镀锌等除锈防锈工艺。各构件或部件之间通常采用焊缝、螺栓或铆钉连接。因其自重较轻，且施工简便，广泛应用于大型厂房、场馆、超高层领域。钢结构容易锈蚀，一般钢结构要除锈、镀锌或涂料，且要定期维护。
