Commercial buildings

Commercial buildings are buildings for people to engage in various business activities. Including: retail stores, shopping malls and wholesale markets for all kinds of daily necessities and means of production; Trading places in finance, securities and other industries and business office buildings for business activities; Various service buildings, including hotels (including hotels, hotels, guest houses, etc.), restaurants (including Chinese and Western restaurants, restaurants, bars, etc.), cultural and entertainment facilities (such as karaoke dance halls, etc.), clubs (also known as member clubs, which provide members with places to rest, eat, party, cultural entertainment and sports activities), etc.

What is steel structure building?

Steel structure building is a new type of building system, which breaks through the industrial boundary between real estate industry, construction industry and metallurgy industry and integrates into a new industrial system.

Compared with traditional concrete buildings, steel structure buildings replace reinforced concrete with steel plate or section steel, which has higher strength and better seismic resistance. And because the components can be manufactured in factory and installed on site, the construction period is greatly reduced. Because steel can be reused, it can greatly reduce construction waste and be more green and environmental friendly. Therefore, it is widely used in industrial and civil buildings all over the world.

The application of steel structure buildings in high-rise and super high-rise buildings is becoming more and more mature, and gradually becomes the mainstream construction technology, which is the development direction of buildings in the future.

Steel structure building is a building with load-bearing structure composed of building steel. The load-bearing structure is usually composed of beams, columns, trusses and other components made of section steel and steel plates. Together with roof, floor, wall and other enclosure structures, it forms a whole plant building.

Building section steel usually refers to hot-rolled angle steel, channel steel, I-beam, H-beam and steel pipe. The building with load-bearing structure composed of its components is called section steel structure building. In addition, the load-bearing structure building formed by cold-rolled, crimped or non crimped L-shaped, U-shaped, Z-shaped and tubular thin-walled steel, as well as its components made of small steel such as angle steel and reinforcement, is generally called light steel structure building. There are also suspension structure buildings with steel cables, which also belong to steel structure buildings.

The steel has high strength and elastic modulus, uniform material, good plasticity and toughness, high accuracy, convenient installation, high degree of industrialization and rapid construction, but it has poor corrosion resistance and fire resistance and needs regular maintenance.
