Prefabricated Steel Structure Building Q235B Steel Structure Garment Factory
Prefabricated Steel Structure Building/Q235B Steel Structure Garment Factory. This is a Prefabricated Workshop Buildings that we design, fabricated the steel structure and installation. Welded H-section steel columns and beams are connected by high strength bolts to be the main frame structure of the buildings. Steel structure is made from organized combination of structural steel members designed to carry loads and provide adequate rigidity. The members of the steel structures are made of steel and are joined by welding, riveting or bolting. These structures are reliable and require less material than other types of structures due to the high strength of steel which are distinguished by the diversity of their shapes and their architectural expressiveness.
Although the density of steel is larger than that of other building materials, its strength is very high. Under the same force, the steel structure has a small weight and can be made into a structure with a large span.
Structural Construction of Prefabricated Steel Structure Factory Building The industrial factory building adopts prefabricated steel structure factory building as a chemical plant, equipped with electric single-girder crane. We were the general contractor for this project and our scope of work included design drawings, fabrication of all steel structural components and roof and wall sandwich panels, followed by installation.
Although steel is denser than other building materials, it has high strength. Under the same force, the steel structure has a small self-weight and can be made into a large-span structure.
