Product Description
Customizable Q355B Multi-Story Steel Structure Commercial Buildings
Steel structure commercial buildings are engineered systems composed of square tube columns, steel roof and platform beams, steel decking boards, roof cladding, wall cladding, and accessories including studs and bolts. Optional components such as aluminum windows, doors, glass curtain walls, plaster board ceilings, and floor tiles are available upon request.
As prefabricated buildings, steel structures differ from precast concrete in that their main load-bearing components are manufactured from steel, consisting of beams, columns, trusses, and other structural elements made from section steel and steel plates. Components are typically connected on-site using weld seams, bolts, or rivets.
Product Specifications
Main Structural Components
The primary framework includes columns, beams, and supporting members designed in accordance with international standards such as GB and IS codes.
Roof and Wall Systems
Roof options include sandwich panels, stone painted sheets, or poured concrete based on roof slope and client requirements. Walls typically utilize PU sandwich panels or rock wool sandwich panels for enhanced aesthetics and thermal insulation.
Floor Decking
Steel decking boards for multi-story office buildings feature effective widths of 688mm or 750mm, serving as form boards and concrete supports on steel platforms.
