The high-strength prefabricated steel structure warehouse provides a comprehensive one-stop solution with fast delivery and experienced installation guidance. This building system is composed of two main parts:
Portal Steel Frame Design
The steel frame features a portal steel frame structure, including steel columns, beams, and bracing. Together with the external enclosure, it forms a fully enclosed building capable of withstanding severe weather conditions such as strong winds, heavy rain, and snow.
Precision Fabrication & Efficient Installation
All metal components are cut, welded, drilled, and painted in our workshop before transportation to the construction site. Each component is bolted on-site for quick and labor-saving installation.
Structural Components
The steel frame comprises five key structural elements:
-
Tension members
-
Compression members
-
Bending members
-
Combined-stress members
-
Connections
Construction Features
- Lightweight construction with high strength, large spans, and reduced foundation pressure
- Shorter construction period compared to concrete buildings with simple on-site assembly
- 20-30% lower investment cost than traditional buildings
- High fireproof performance and corrosion resistance
- Buildings can be disassembled, moved easily, and recycled with no pollution
