Why should promote the high-rise steel structure reasons

Promotion of steel structure high-rise building:
1 greatly save construction time, construction is not affected by the season;
2 increase the use of residential space, reduce construction waste and environmental pollution;
3 building materials can be reused, stimulating the development of new building materials industry;
4 good seismic performance, easy to use in the transformation, flexible and convenient, to bring comfort, etc..
In recent years, compared to the steel structure building in brick concrete structure building in environmental protection, energy saving, high efficiency, factory production has obvious advantages. Humans began to use iron since 1670s, the beginning of nineteenth Century the use of wrought iron bridges and the construction of housing, steel structure than the history of the development history of the development of reinforced concrete structure is long, its vitality is growing. In the United States, low rise buildings, such as non residential buildings below two floors of the market has more than 70% of the construction of metal products.
101 high-rise building in the world has been completed, the reinforced concrete structure of 16 buildings, 59 buildings of steel structure, steel concrete mixed structure of different forms of the 27 buildings; we can see that the development of steel structure will promote the construction industry, metallurgical industry, machinery industry, automobile industry, oil industry, agriculture, commerce, transportation industry the rapid development of.
