The characteristics of steel are high strength, light weight, good overall rigidity, and strong resistance to deformation. Therefore, it is particularly suitable for the construction of large-span, super-high and super-heavy buildings; the material has good homogeneity and isotropy, which is ideal for elasticity. The structure is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have greater deformation, and can well withstand dynamic loads; the construction period is short; its degree of industrialization is high, and it can be specialized production with a high degree of mechanization.

Steel structure should study high-strength steel to greatly increase its yield point strength; in addition, new types of steel should be rolled, such as H-shaped steel (also known as wide flange steel) and T-shaped steel and profiled steel plates to adapt to large-span structures and The needs of super high-rise buildings.

In addition, there is a light steel structure system without thermal bridge. The building itself is not energy-efficient. This technology uses ingenious special connectors to solve the problem of cold and hot bridges in the building; the small truss structure allows cables and water pipes to pass through the wall. The decoration is convenient.
