Product Overview

Prefabricated steel structure building consists of factory-made components that are assembled on-site to form a complete rigidity system. Due to the high strength grade of steel, these structures are highly reliable and material-efficient compared to concrete or wood.

Key Characteristics

⭐ High Strength & Lightweight: Easier to transport and ideal for large spans or high-rise structures.
⭐ Seismic Performance: Uniform internal structure provides better resistance to impact and dynamic loads.
⭐ Fast Installation: Highly mechanized manufacturing ensures precision and rapid on-site assembly.
⭐ Environmental Friendly: Minimal construction waste; materials are fully recyclable.
⭐ Sealing Performance: Supports excellent air and water tightness for pressure containers or specialized storage.

Frequently Asked Questions

What is the lifespan of a prefabricated steel structure?

Our steel structures are designed for long-term durability, with a typical service life ranging from 50 to 70 years depending on the maintenance and environmental conditions.

How does the structure perform against fire?

While steel loses strength at very high temperatures (around 600ºC), we provide protection using heat insulation boards and refractory materials to meet specific building fire safety levels.

Can I customize the size and design of the building?

Yes, all structures are fully customized. We can develop designs based on your specific drawings, required dimensions, and local weather loads (wind, snow, seismic).

Is the material environmentally friendly?

Absolutely. Steel is a green building material. The demolition of such structures generates almost no construction waste, and the steel components are 100% recyclable.

What surface treatments are available to prevent rust?

We offer high-grade sandblasting (SA 2.5) followed by two layers of anti-rust painting or galvanization, depending on the client's requirements and the building's environment.

Do you provide installation assistance?

We provide professional site management and installation supervision. Engineers can be sent to assist your local construction team to ensure the building is assembled correctly.
