Sustainable Commercial Prefab Square Tube And H Section Steel
Affordable And Sustainable Multi Story Steel Structure Commercial Building
Product Description
Structural steel framing is a durable, reliable, cost-effective, and sustainable option for low-rise, mid-rise and high-rise building projects. It typically refers to building frame systems where vertical and horizontal structural elements are formed by a system of structural steel beams and columns. Column spacing varies depending on architectural requirements. The range of available shapes and sizes allows virtually any architectural requirement to be met.
Structural steel framing is designed, fabricated and erected in accordance with steel structure standards. It is adaptable to almost any architectural layout and is used routinely on various building projects. Structural steel is the most popular framing material for non-residential buildings worldwide, with over half of constructed square footage framed in structural steel annually.
Product Parameter
The main components of steel structure commercial building:
- Main Frame: Primary load-carrying members include columns, beams and supporting members. Frame is erected by bolting end plates together. All steel sections and welded plate members are designed to meet international standards (GB, IS) and customer specifications.
- Roof and Wall Cladding: Roof options include sandwich panel, stone painted sheet or concrete depending on slope and requirements. Walls typically use PU or rock wool sandwich panels for aesthetics and insulation.
- Steel Decking Board: Flooring for multi-storey buildings with effective width of 688mm or 750mm, serving as form board and concrete support.
