Modern Commercial Building Steel Prefab Commercial Building
Multi Story Prefabricated Commercial Buildings Construction With Spacious Interiors
Steel structure commercial buildings are made primarily of steel, which makes them strong and durable. They can withstand various weather conditions. One great advantage is their open design, which allows for flexible floor plans and spacious interiors. With fewer support columns, the usable space is maximized, providing ample room for offices and warehouses. Additionally, steel commercial buildings are cost-effective, as they require less maintenance and have shorter construction times compared to traditional buildings.
Product Parameters
The main components of steel structure commercial building are:
- Main frame: Includes columns, beams and other supporting members. The frame is erected by bolting the end plates of connecting sections together. All steel sections are designed in accordance with international codes and standards (GB, IS) to meet customer specifications.
- Roof and wall cladding: Roof can be sandwich panel, stone painted sheet or pouring concrete depending on requirements. Wall is usually PU sandwich panel or rock wool sandwich panel for aesthetics and heat insulation.
- Steel decking board: Used for multi-storey floor systems with effective width of 688mm or 750mm, serving as form board and concrete support.
