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 components can be manufactured in factories and installed on site, the construction period is greatly reduced. Due to the re usability of steel, construction waste can be greatly reduced, and it is more environmentally friendly. Therefore, it is widely adopted by countries all over the world and used in industrial and civil buildings.

At present, the application of steel structure buildings in high-rise and super high-rise buildings is becoming more and more mature, and it has gradually become the mainstream construction technology, which is the development direction of future buildings.

Steel structure building is a building in which construction steel constitutes a load-bearing structure. Generally, beams, columns, trusses and other components made of section steel and steel plates constitute load-bearing structures. Together with the roof, floor and wall and other enclosure structures, they form a replanted building.

Construction section steel usually refers to hot-rolled angle steel, channel steel, I-beam, H-section steel and steel pipe. A building whose components constitute a load-bearing structure is called a profiled steel structure building. In addition, cold-rolled thin steel plates, crimped or non-crimped L-shaped, U-shaped, Z-shaped and tube-shaped thin-walled steel, as well as the load-bearing components formed by small steel such as angle steel, steel bar, etc. Structural buildings are generally called light steel structures. There are also suspended-cable structure buildings that use steel cables, which are also steel structure buildings.

The steel has high strength and elastic modulus, uniform material, good plasticity and toughness, high precision, convenient installation, high industrialization, and fast construction. However, it has poor corrosion resistance and fire resistance and requires frequent maintenance.

Steel structural components are conducive to manufacturing in processing plants and assembly on construction sites. The processing plant specializes in the production of finished products of steel structure building components with high precision, high manufacturing efficiency, faster assembly on construction sites, and fast deadlines. Steel structure building is the most modern structure.
