Product Description
Our pre-engineered steel structure warehouse buildings offer superior safety and high mechanization. The steel components use single materials in finished form, enabling simple processing, high mechanization, and short construction cycles.
Key advantages include:
- Lightweight construction with excellent mechanical properties to withstand heavy loads
- Compact structural sections - steel roof trusses weigh just 1/3 to 1/4 of reinforced concrete equivalents
- Easy transportation due to lightweight design
- Flexible layout with high building area utilization
- Effective solutions for ventilation, lighting, insulation, drainage, and personnel evacuation
