Compund Steel Grating

The Composite Steel Grate is made up of a steel plate with a certain span capacity and a tread plate on the sealing surface. It can be made with any type of steel grate and different thickness tread steel plates. His advantages are as follows:
1. high strength, light structure
2. strong anticorrosion and durable
3. beautiful appearance, bright surface
4. do not accumulate dirt, not rain snow, not water, self clean, easy maintenance
5. ventilation, lighting, heat dissipation, skidproof, and good explosion-proof.
6. easy to install and disassemble.
