The FRP grating is made of steel, and steel is easy to rust in the air, water or soil, or even completely damaged. It is understood that the annual steel loss due to corrosion accounts for about 1/10 of the entire steel output, so people have developed the galvanizing process.
The galvanized steel and FRP grating is beautiful in craftsmanship and has a certain decorativeness. Galvanizing includes hot-dip galvanizing and electro-galvanizing, both of which can be applied to the surface treatment of FRP gratings. Although both can be applied, the essential difference between the two is still different.
1. In terms of price: the price of electro-galvanized steel grating is low, and the price of hot-dip galvanized steel grating is 3-4 times higher than that of electro-galvanizing.
2. Environmental pollution: Hot-dip galvanizing produces less "three wastes" in the production process than electro-galvanizing, and has less impact on the environment.
3. In terms of production efficiency: the production efficiency of hot-dip galvanizing is particularly high, and the residence time of the parts in the hot-dip galvanizing tank is relatively short.
4. Usage: hot-dip galvanized steel grating has a thick zinc-zinc coating, fine, uniform and non-porous crystals, good corrosion resistance, slower corrosion in acid, alkali and other mist, which can effectively protect the steel substrate than electroplating Zinc has a long service life and can be used for an additional 40 years.
Hot-dip galvanized glass steel grating not only has the corrosion resistance of electro-galvanized steel, but also has strong corrosion resistance that can not be compared with electro-galvanized. Hot-dip galvanizing can make a thicker and dense pure zinc layer cover the surface of steel. It can also avoid the contact of the steel substrate with any corrosive solution, and protect the steel substrate from corrosion.
