 feature

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

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.
