Customizable Q355B Prefabricated Steel Buildings Commercial
Product Description
Steel structure commercial building is composed by square tube columns, steel roof and platform beam, steel decking board, roof cladding, wall cladding and accessories like studs, bolts, etc. Aluminium windows, door, glass curtain wall, plaster board ceiling and floor tiles can be also provided if needed.
As a rising prefabricated building solution, steel structures differ from precast concrete in that their main load-bearing components are all made of steel, consisting of steel beams, columns, trusses and other components made of section steel and steel plates. Each component is typically connected by weld seams, bolts or rivets on site.
Product Specifications
The main components of steel structure commercial building are:
- Main Frame: Includes columns, beams and supporting members designed in accordance with international codes (GB, IS) using Q235/Q355B welded H section steel.
- Roof and Wall Cladding: Options include sandwich panels, stone painted sheets or concrete depending on requirements.
- Steel Decking Board: Floor solution for multi-storey buildings with effective widths of 688mm or 750mm.
