Material

high quality low carbon steel,  Stainless Steel,ASTM A36 A1011 A569 Q235

feature

1.High strength, light structure: solid grid pressure welding structure has advantages of high load, light structure, easy installation, etc. 

 

2. Fine appearance, durable in use: hot zinc dipping surface treatment makes it own fairly good corrosion resistance, bright and beautiful surface.

 

3. Good ventilation, lighting, thermal, anti-explosion, and anti-skid performance

 

4. Prevent dirt deposition.
