Steel structure building is a kind of building which takes the steel as main bearing structure. Steel structure building is composed of components such as beams, columns, trusses, etc. made of section steel and steel plate. The steel structure building and enclosure structure such as the roof, floor and wall surface together form a complete building.
The building section steel mainly contains the components such as the angle steel, channel steel I-beam, H-beam and steel pipe that are rolled at high temperature. The system of the load-bearing structure that is formed by the thin steel plate that is formed the cold rolling process, L-shaped, U-shaped, Z-shaped and pipe-shaped, and then combined with the small size steel such as the angle steel and reinforcement is usually defined as the light steel structure building.
Because the steel structure building has higher strength and modulus of elasticity, uniform material, good plasticity and toughness, fast, relatively convenient installation, high degree of industrialization, and compared with wood, concrete and masonry, the dead weight of the steel structure is smaller. In addition, the of the steel structure is small, and about 8% of the effective building area can be increased compared with the reinforced concrete structure. Therefore, many enterprises will choose to use steel buildings.
