Compared with traditional concrete buildings, steel structure buildings use steel plates or section steel instead of reinforced concrete, which has higher strength and better seismic resistance. And because the steel parts can be produced in factory and installed on-site, the construction period is greatly reduced. At the same time, due to  steel can be reused, construction waste can be greatly reduced, and it’s more environmentally friendly. Therefore, it is widely adopted in the world, especially used in industrial buildings and civil buildings 

At present, the use of steel structure buildings in high-rise and super-high-rise buildings is becoming increasingly mature, and it has gradually become the mainstream building technology, and the real estate industry, construction industry and metallurgy industry are linked together to form a new industrial system .Common commercial steel structure building includes theaters, shopping malls, stadiums, exhibition hall, parking, etc., the world-famous Eiffel Tower, Beijing Bird's Nest, Dubai Sailing Hotel, New York Empire State Building are all steel structure building.
