The components of the steel structure have small section, light weight, easy to transport and installation, suitable for large span, high height, heavy bearing structure. Suitable for withstand impact and dynamic load, with good seismic internal structure of steel is uniform with high reliability. Factory mechanized production of steel structure components finished products of high precision, high production efficiency, site assembly speed, short construction period. Steel structure is composed of steel material structure, is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts silanization, pure manganese phosphating, washing and drying, galvanized and other rust removal and rust prevention processes. The components or components are usually connected by welds, bolts or rivets. Because of its light weight, and simple construction, it i
