3. Surface Treatment: Untreated, Painting or Hot dip Galvanizing
4. 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.
