Steel Prefabricated Structural Frame

Product Description

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.

In modern buildings, steel structures are used in almost every type of structure, including heavy industrial buildings, multi-storey buildings, equipment support systems, infrastructure, bridges, towers, airport terminals, and more.

Characteristics of Steel Structures

High Strength & Lightweight Steel has a high modulus of elasticity. Compared with concrete and wood, steel structures are lighter, making them easier to transport and install, especially for large spans and high-rise structures.
Superior Reliability Uniform internal structure and good seismic performance allow steel to undertake dynamic loads effectively. Actual performance aligns closely with calculation theories.
High Mechanization Components are factory-manufactured with high precision and rapidly assembled on-site, significantly reducing construction time.
Excellent Sealing Welded structures provide superior air and water tightness, ideal for high-pressure containers, large oil sumps, and pressure pipes.
Green & Recyclable Steel structures generate minimal construction waste during demolition and the material is 100% recyclable.

Frequently Asked Questions

1. What are the main advantages of steel structure buildings?
Steel structures offer high strength-to-weight ratios, seismic resistance, rapid construction times, and are highly sustainable as the material is recyclable.
2. How long does a steel structure building last?
With proper maintenance and high-quality anti-corrosion treatments like galvanization or painting, these structures typically have a lifespan of 50 to 70 years.
3. Are steel structures fire-resistant?
While steel is heat-resistant, its strength decreases at high temperatures (above 600°C). For fire protection, we use refractory materials or insulation boards to meet safety standards.
4. Can the building size be customized?
Yes, all our steel buildings are customized. We can design the width, length, eave height, and roof slope based on your specific requirements and local site conditions.
5. What information is needed for a design quote?
To provide an accurate design, we need dimensions (L x W x H), local wind speed, snow load, live roof load, and whether any cranes or specific door/window configurations are required.
6. How do you handle rust prevention?
All structural members undergo professional sandblasting to Sa2.5 grade followed by multiple layers of anti-rust painting or hot-dip galvanization for maximum corrosion resistance.
