The most important thing in the use of general steel grating is to deal with the basic oxidation problem. Hot-dip galvanized steel grating is also called steel grating, but steel grating is the general name of all metal plates. Apply zinc or spray paint on the surface of ordinary steel grating, so that it can easily prevent the steel grating from rusting in daily use.

      In fact, there are many ways to prevent oxidation. Of course, spray painting is one of them, but in most cases, what we see is hot-dip galvanized steel grating. Of course, the reason is that spray painting cannot achieve good anti-corrosion effect at all. The difference can not achieve the purpose of anti-corrosion at all, and the cost is also high, so most of them are galvanized.

In fact, metal plating on the outer layer forms a form of chemical primary battery, which is called electroplating. After the steel is plated with zinc, it can protect the plated parts, even if it is oxidized first, it should be It is zinc, which plays a protective role, is simple and environmentally friendly, and has a low cost.
