Professional Steel Portal Frame Warehouse
This steel structure warehouse is engineered for maximum safety and durability. Manufactured according to international standards, it features excellent load-bearing capacity and strong resistance to earthquakes, storms, and corrosion. The rigid steel frame ensures stable performance for long-term use, while wall and roof panels provide superior heat insulation and soundproofing. The open-span design creates large usable space, and we supply complete warehouse systems with reliable quality and professional after-sales support.
Building Components & Specifications
Structural Components
- Primary Framing: Columns and beams made from H-section steels (hot-rolled or welded), factory-primed with protective coatings or galvanization for superior anti-rust protection
- Secondary Framing: Purlin and tie bar systems fixed to columns and beams with common bolts
- Bracing: Round steel knee bracing and supporting parts that enhance structural stability and durability
- Cladding: Roof and wall panels using color-coated corrugated steel sheet or steel sandwich panels, hot-dipped with zinc and aluminum compounds for weather protection and longevity
- Windows & Doors: Plastic steel windows, aluminum-alloy windows, sliding doors, and folding doors
- Optional Features: Gutter, downpipe, transparent sheets, ventilators, and bridge cranes available per client requirements

Performance Advantages
The main frame utilizes high-strength Q345/S355JR steel with exceptional load-bearing capacity, impact resistance, and deformation resistance. Engineered to withstand 8-degree seismic intensity, heavy snow loads of 0.7-1.2 kN/㎡, and level 12 strong winds. All steel components feature hot-dip galvanizing + polyester paint double anti-corrosion treatment, effectively isolating air, moisture, and chemical corrosion to extend service life beyond 50 years.
Environmental Optimization
Specially optimized for harsh environments including coastal areas (anti-salt spray corrosion), cold regions (anti-low temperature brittle fracture), and windy locations (wind-resistant structural design). Maintains stable performance long-term without frequent maintenance, significantly reducing operational costs.
