Galvanized Walkway Grating
Galvanised steel grating is the anti-rust treatment after the production of steel grating. There are 2 kinds of hot-dip galvanised steel grating and electro-galvanised steel grating. Galvanised steel grating has the advantages of ventilation and light transmission, anti-slip, strong bearing capacity, beautiful and durable, easy to clean, easy to install and so on.
After galvanised steel grating, it will have good anti-corrosion effect. Because the zinc layer is equivalent to a layer of protection, the thicker the galvanised layer, the better the anti-corrosion effect, the longer the service life. The service life of galvanised steel grating can be up to 20 or 30 years, which greatly saves the purchase cost!

Advantages of hot dip galvanised steel grating
1. Simple structure and light weight. Steel mesh grating is a square grid made of cross-combination and pressure welding of flat steel and twist bars. It has a simple structure and is light in weight. It is the most resource-saving way to ensure the same bearing capacity.
2. Large drainage capacity. The spacing between steel gratings is mostly 30*100mm, and the large hole type allows the drainage volume to reach more than 80%.
3. Anti-corrosion and anti-aging. The material of the metal walkways gratings is carbon steel with hot-dip galvanizing surface treatment. The 500g zinc layer allows the steel grating to be used for more than 10 years in humid, dark, acidic and alkaline environments, making it durable.
4. Strong carrying capacity. The load-bearing capacity of steel grating plate is mainly flat steel, which has strong lateral pressure resistance.
5. Beautiful appearance. The cross combination of flat steel and horizontal bars is simple, elegant, smooth and smooth.
