4> Surface process of steel grating types:hot-dipped galvanized,electro-galvanized ,spray and brushing. 95% people choose hot-galvanized because its anti-acid and alkali corrosion capacity range is from PH6 to PH12.5,a stable protective film will be formed on the zinc surface.A good anti-corrosive property to be resulted.
5> Attractive appearance: Simple outline,silver colour and modern style.
6> Optimum water draining:Water leakage area reaches 83.3%,which is double larger than that of cast iron.
7> Hot-dip galvanizing:Good antirust performance,maintenance free and free replacement.
