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. It is a metal structure made of structural steel members connected to each other to carry loads and provide complete rigidity.
🏗️
High Strength & Lightweight:
Steel has high strength and high modulus of elasticity. Compared with concrete and wood, the steel structure is easier to transport and install, making it ideal for large spans and high-rise structures.
🛡️
Seismic Performance & Reliability:
Uniform internal structure provides excellent seismic performance. The actual working performance conforms closely to calculation theories, ensuring high reliability.
⚙️
Industrialized Construction:
Components are precision-manufactured in factories and quickly assembled on-site, significantly reducing construction time.
💧
Superior Sealing:
Welded structures can be completely sealed, providing excellent air and water tightness for high-pressure containers and pipes.
♻️
Green & Sustainable:
Steel is 100% recyclable. Demolition generates almost no construction waste, supporting energy-saving and environmental goals.

Production & Processing
1. Raw Material Preparation: Cutting steel plates or using international size H sections, angle steel, and tubes.
2. Assembly & Welding: Professional welding of members into beams and columns followed by rigorous quality checks.
3. Sand Blasting: Reaching international 2.5 high-grade standards for superior rust resistance.
4. Painting: Protective coating applied within 2 hours of sandblasting in any customer-specified color.
5. Final Inspection: Client-led inspection or video verification before packing.
Installation Services
We provide professional engineering designs and full-site management. Our engineers can be sent to supervise installations, ensuring the structure is built to the highest standards.
Frequently Asked Questions
What is the lifespan of a prefabricated steel building?
Our steel structures are designed for long-term durability, with a warranty and expected lifespan of 50 to 70 years.
Are steel structures fireproof?
Steel is heat-resistant but will lose strength at very high temperatures (around 600°C). For buildings requiring fire protection, we apply refractory materials to enhance the fire resistance level.
How do you prevent rust and corrosion?
We use professional sandblasting (SA 2.5 grade) followed by high-quality painting or galvanization. For maritime environments, special zinc anode protection can be applied.
Can I customize the size and design?
Yes, all buildings are customized. We design based on your specific requirements, including wind speed, snow load, and earthquake parameters.
Is the construction process environmentally friendly?
Absolutely. Steel is a green material that is 100% recyclable. The prefabrication process also significantly reduces on-site construction waste.
What information is needed for a design quote?
Please provide the building dimensions (Length x Width x Eave Height), local wind speed, snow load, live roof load, and if a crane is required.
