Steel structure is mainly made of steel, and it is one of the main types of building structures. Steel is characterized by high strength, light weight and stiffness, so it is suitable for building large span and ultra high and super heavy buildings;
The structural beam, as its name suggests, is a structural beam made of steel.
Homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; processing high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc.. Its disadvantage is poor fire resistance and corrosion resistance. Mainly used in heavy duty workshop bearing frame, dynamic power plant structure, plate and shell structure, high tower and mast structure, bridges and warehouses and other large-span structure, high-rise and super high-rise buildings.
