Our country is a big country of steel ,steel production reached more than 700 million tons, the actual production capacity of more than 1 billion tons, but the prefab steel structure used in construction to less than 5%.
Steel building has the advantage of good seismic performance, fast construction and can be recycled , which meets the requirements of the green building,But is not very well in the civil building applications , higher cost is the directly reason .
Prefab Steel structure building is a new type of building structure system. The building structure system is formed by the main framework through linking up the H beam,C purline,Z purline,U purline steel components.
Roof and wall using a variety of panels together with other components such as windows and doors. The metal structure building has the advantages of wide span, high strength, light weight, low cost,temperature protection, save energy,beautiful appearance, short construction time, good effect of insulation, long using life, space-efficient, good seismic performance, flexible layout,etc , The steel building is widely used in large warehouse,workshop,bridge, supermarket and so on
Currently except metal structure the other is less in industrial building ,especially the lack of new wall materials, industrial building is weak , less wall plank product in market , poor quality but price higher , Doesn’t satisfy the need of the metal structure housing industrialization also the main cause of the high cost in the steel housing .
In recent years practice has proved that successful technology of steel residential building with research, complete industrial chain of the enterprises, combined with some preferential policies to steel residential building the price could accepted by the market , with the enlargement of the scale, cost also is now reduced.
Steel has many advantages, however, only 1% less than in the residential buildings ,Industry development Suggestions are put forward to guide the developing of steel in residential buildings .Steel industry and its upstream and downstream industry chain in China push the developing of steel structure and promote advanced Prefab steel building system and its supporting products to develope in the direction of green environmental protection
