钢结构是由钢制材料组成的结构，是主要的建筑结构类型之一。
Steel structure is a structure composed of steel materials, which is one of the main types of building structures.
结构主要由型钢和钢板等制成的梁钢、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。
The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate. Silanization, pure manganese phosphating, washing and drying, galvanizing and other anti-rust technologies are adopted. Welds, bolts or rivets are usually used to connect components or components.
在全球范围内，特别是发达国家和地区，钢结构在建筑工程领域中得到合理、广泛的应用。钢结构行业通常分为轻型钢结构、高层钢结构、住宅钢结构、空间钢结构和桥梁钢结构五大子类。
In the global scope, especially in developed countries and regions, steel structure has been reasonably and widely used in the field of construction engineering. Steel structure industry is usually divided into five sub-categories: light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure.
