Clear Span Pre Engineered Buildings Prefabricated Steel Frame Warehouse
This is a Clear Span Pre Engineered Buildings As Prefabricated Steel Frame Warehouse. We design the proposal drawing, fabricate all the steel structure components & provide all the necessary accessory such as window, doors, bolts, etc. Then install it on construction site.
Compared with ordinary reinforced concrete structure, prefabricated steel structure buildings has the advantages of fast construction, low construction cost, good earthquake resistance and high recovery rate. The strength and elastic modulus of steel are many times higher than that of masonry and concrete. Under the same load conditions, the quality of steel components is light. The steel structure is suitable for large-scale production in factories and has a high degree of industrialization. It can integrate advanced products such as energy saving, waterproofing, heat insulation, doors and windows, and complete application. It will integrate design, production and construction to improve the level of the construction industry.
