Steel Grating Feature
1) The steel grating can reduce the supportive material, investment, save workman and time.
2) It can be used in almost all applications.
3) Lightweight and economical.
4) Low maintenance cost, because the surface will be galvanized, the anti-corrosion is 15~30 times than ungalvanized.
Application:
1) It can be used in urben construction as drainage trench cover to drain water and keep ground dry.
2) The serrated steel gratings will be used in the port, parking lot, farmland and other places to be walk platform for pedestrian and vehicles access and passing.
3) Forge-Welding gratings also will be used for industry platform, power plant, water treatment industry, tower platform, etc.
4) Serrated steel gratings also be guardrail for garden, villa, balcony, highway, etc.
