drain cover mesh 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.
