Precision Manufacturing Process

In our workshop, metal components are produced through a controlled process of cutting, welding, drilling, and painting before being delivered to the construction site. Each component is bolted for assembly, enabling quick and convenient installation that helps significantly reduce labor costs.

Main Structural Components
  • Tension Members: Designed to withstand tensile forces
  • Compression Members: Engineered to support compressive loads
  • Bending Members: Crafted to resist bending stresses
  • Combined Stress Members: Capable of handling multiple types of stress
  • Connections: Ensure structural integrity and stability
Construction Features
Lightweight yet high-strength design, offering large-span capacity and reduced foundation pressure
Shorter construction period than traditional concrete buildings, thanks to simple on-site assembly
20-30% lower investment cost compared with conventional construction methods
Excellent fire resistance and strong corrosion protection for long-term reliability
Environment-friendly & flexible: buildings can be disassembled, relocated, and recycled with minimal environmental impact
