Steel structure is composed of steel, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss, section steel and steel plate. Silanization, pure manganese phosphating, washing and drying, galvanizing and other anti-rust technologies are adopted. Welding, bolting or riveting are usually used to connect parts or components. Because of its light weight and simple construction, it is widely used in large-scale factory buildings, sites, super high-rise and other fields.

At present, brick-concrete structure and reinforced concrete frame structure are still the main types of residential buildings in China, and the industrial system of steel structure residential buildings in China has just started. With the development of housing industrialization, many advantages of light steel structure housing provide a stage for light steel structure housing.
