What are Steel Buildings?

Steel structure building is a new type of building system that opens the industry boundary between the real estate industry, construction industry, and metallurgy industry, and integrates into a new industry system. This is the steel structure building system that people in the industry are generally optimistic about.

A steel structure building is a building that is constructed of building steel bearing structure. Beams, columns, trusses, and other components usually made of steel and steel plates form load-bearing structures. It forms a whole planted building together with the enclosing structures such as roof, floor and wall.

Building steel generally refers to hot-rolled angle steel, channel steel, I-beam, H-beam and steel pipes. The building whose load-bearing structure is constituted by its components is called a steel structure building. In addition, the thin steel plate is cold-rolled, rolled or unrolled L-shaped, U-shaped, Z-shaped and tube-shaped thin-walled steel, and the load formed by it and components made of small steels such as angle steel, steel bars, etc. Structural building, generally called light steel structure building. There are also suspension structure buildings using steel cables, which are also steel structure buildings.

The strength and elastic modulus of steel are high, the material is uniform, the steel structure made is good in plasticity and toughness, high accuracy, easy installation, high degree of industrialization, and fast construction, but it has poor rust resistance and fire resistance, and requires frequent maintenance. ^[1]

After China's annual steel output exceeds 100 million tons, the price of steel has dropped from the price in 1995, such as steel structure manufacturing and installation costs (including materials, manufacturing, transportation, and installation) from 9,000-10,000 yuan / ton in 1995 to 2000 At the end of the year, it was 5000-6000 yuan / ton. In order to meet the 2008 Olympic Games, Beijing will invest 180 billion yuan in the next few years for stadium reconstruction, urban infrastructure construction, and the construction of a number of high-quality residential and high-end hotels. At the same time, Beijing belongs to the earthquake fault zone for the 8-degree earthquake defense Area. Therefore, steel construction will undoubtedly become the mainstream of Beijing's future architecture. ^[2]
