Product Description
Steel Construction Materials
Prefabricated steel structure building is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on-site to form the complete building.

What is steel structure?

A steel structure is a metal structure made of structural steel members that are connected to each other to carry loads and provide complete rigidity. Due to the high strength grade of steel, this structure is reliable and requires less raw material than other types of structures such as concrete structures and wood structures.

Character of Steel Structure

  • High Strength But Light Weight: Easier to transport and install, suitable for large spans and high-rise structures.
  • Toughness & Reliability: Excellent seismic performance with uniform internal structure.
  • High Mechanization: Components are precision-manufactured in factories for quick on-site assembly.
  • Good Sealing Performance: Supports air-tight and water-tight requirements for pressure containers and pipes.
  • Heat-resistant: Steel properties are stable below 150°C (requires refractory protection for higher fire ratings).
  • Environmental Friendly: Low carbon, energy-saving, and materials are 100% recyclable.

Frequently Asked Questions
What are the main advantages of a steel structure?
Steel structures offer high strength-to-weight ratios, seismic resistance, rapid installation, and are environmentally friendly as the materials are fully recyclable.
How long does a steel building typically last?
With proper maintenance and surface treatment (painting or galvanizing), our steel structures are designed for a service life of 50 to 70 years.
Is the steel structure fireproof?
While steel is heat-resistant, its strength decreases at high temperatures. We use refractory materials or insulation boards to meet specific fire protection requirements.
Can you provide custom designs?
Yes, we provide fully customized designs based on your specific requirements including dimensions, local wind/snow loads, and intended use.
How is the structure protected against corrosion?
All components undergo sandblasting to international standards (Sa 2.5) followed by high-quality anti-rust painting or hot-dip galvanization.
What is required for the installation?
Components are prefabricated and bolted together on-site. We can provide engineering supervision to guide your local construction team through the process.
