Steel structures are structures made of steel materials and are one of the specific architectural structural characteristics. The structure is mainly composed of components such as steel beams, steel beams, and steel pipe trusses made of channel steel and thick steel plates, and uses rust prevention processes such as chlorosilane treatment, pure manganese phosphating treatment, water washing and drying treatment, and hot-dip galvanizing. The components or between components are generally welded, anchored with foundation bolts, or riveted. Because of its relatively light weight and simple construction, it is widely used in large and medium-sized industrial plants, exhibition halls, high-rise residential buildings, and other industries.

　　Steel structure buildings are an environmentally friendly building system, connecting the boundaries between the real estate industry, the construction industry, and the metallurgical industry, and combining to form a new industrial chain system. This is the steel structure building system that professionals widely value.

　　Compared with traditional concrete buildings, steel structure buildings use thick steel plates or channel steel instead of concrete structures, have higher compressive strength, and are more durable. Moreover, because the components can be mass-produced and installed on-site, the construction period is greatly reduced. Because of the reusability of stainless steel, it can greatly reduce construction waste, making it more environmentally friendly and low-carbon, so it is widely used in industrial and civil buildings in various countries.

　　At present, the application of steel structure buildings in high-rise residential buildings and high-rise buildings is becoming increasingly mature, gradually becoming the main construction technology, and representing the future development trend of buildings.

　　From the perspective of steel structure construction methods, the use of steel structures in buildings is one of the structures with less impact on the urban environment. Among many building structures, when steel structures are used, the steel structure building system has advantages such as light weight and easy installation.
