Prefabricated Metal Buildings Construction / Prefab Workshop Buildings
Prefabricated Steel Frame Structure Metal Building / Steel Building Erection Workshop . Prefabricated steel frame structure buildings are mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. Welding joints, bolts or the like are usually used between components or parts of steel structure workshops, warehouses, office buildings, houses and other buildings. Rivet connection. The steel structure building system has the comprehensive advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery and less environmental pollution. Compared with reinforced concrete structures, it has more "high, large and light". "The unique advantages of the development of the three aspects, in the global scope, especially in developed countries and regions, steel structures have been rationally and widely applied in the field of construction engineering.
We are one-stop service contractor for steel structure design, fabrication and construction. Portal frame steel structure building project is our main business such as prefabricated steel warehouse, workshop, sheds, garage, office building.
