Construction Methodology
Our steel structure commercial buildings feature a systematic construction approach with three main component categories:
- Primary members: H-section steel columns and beams, square tube steel options
- Secondary members: C or Z purlins, bracing systems
- Roof and wall systems: Sheeting or insulated sandwich panels (EPS, fiberglass wool, PU)
- Additional components: Rolling doors, aluminum windows, and custom features
All primary and secondary members undergo precision fabrication including cutting, punching, drilling, welding, and forming in our factory before shipping. On-site assembly utilizes nut and bolt connections for efficient installation and cost reduction.
Applications
Steel structure commercial buildings serve diverse industrial and commercial sectors:
- Office Buildings: Flexible multi-floor layouts with efficient space utilization
- Warehouses & Distribution Centers: Large-scale storage and logistics facilities
- Manufacturing Factories: Spacious production areas for equipment and assembly lines
