Welded Steel Grating Applications:

1. Light chemical industry/Petro-chemistry/Machinery industry/Textile chemistry/Port engineering
2.Oil and grease chemistry/Agriculture husbandry/Horticulture/Steel industry/Waste disposale
3.Food processing/Aquatic breeding/Fertiliazer industry/Phamaceutical industry/Parking lots
4.Cement plants/Oil refinery/Mining and refinery/Power plants/Public utilties
5.Marine engineering/Shipbuilding/Construction material industry/Defense projects/Airport projects
6.Water plants/Sewage disposal/Paper and pulp industry/Construction industry/Transportation industry/Automotive industry

Welded Steel Grating 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.
