We have 23 years experience and 10 national inventions and patents, we have successfully completed more than 1000 projects all over the world. 

What we do:
- Provide Steel Construction solutions  
- Design Steel Structure Construction
- Manufacturing Steel Structure Material and bounding system
- Construction and management of Steel Structure Construction

We specialize in manufacturing:

• various main steel structure

• fabricated green residential steel structure / steel bridge structure / large-span steel structure

• steel structure accessory (Purling/Floor supporting Series/ Staircase etc.)

• high and super high-rise structure

• bounding system (steel plate and composite plate)

 

Characteristics of prefabricated steel structures:

1. Sustainability: Structural steel is virtually 100% recyclable. 90% of all Structural Steel is created from recycled steel.
2. Costs: Large majority of steel manufactured today comes from recycled materials, recycling usage makes the material much cheaper when compared to other materials such as concrete.
3. Durability and Strength: Structural steel is exceptionally strong, rigid, durable, and ductile; making it one of the top materials used in modern commercial and industrial building construction. Furthermore, Steel does not warp, split, crack or corrode when produced and maintained correctly.
4. Nature Disaster Resistant: Steel is inherently an inorganic material with exceptional strength, with built-in resistance to fire, lightning, high wind, heavy snow, mold, and pesky termites. One of steel's greatest feat is its ability to stand up to seismic forces. The ductility of steel allows the framing to absorb an earthquake's destructive energy.  
5. Versatility: Steel is a flexible material that can be produced into a wide array of designs for countless applications.
6. Safety: Steel is safer than concrete during both the construction and operations phase. Prefabricated steel buildings come ready to assemble, requiring less movement of materials and a safer work area.
