Advantages of hot dip galvanizing for steel grating
★ the anti-corrosion ability of hot-dip galvanized steel grating is very good. Generally, the amount of zinc on the hot-dip galvanized steel grating is about 70UM, and the adhesion and hardness of the galvanized layer are good. It is to melt the zinc ingot at high temperature, put some auxiliary materials into it, and then immerse the steel grating in the galvanized tank, so that a layer of zinc layer is attached to the surface of the steel grating. It belongs to electrochemical reaction.
★ the appearance color is bright and beautiful. The steel grating with hot-dip galvanized treatment has a silver white appearance, which looks very high-end and atmospheric from a distance.
◆ service time of hot galvanized steel grating
The service life of hot-dip galvanized steel grating depends on the place of use. In coastal areas, it is generally about 20 years. If the surface is not greatly worn, the time can be longer;
In the inland areas, it is thought that there is no problem for the hot-dip galvanized steel grating to have a service life of more than 30 years due to drought and less rain, low air humidity and less corrosive media;
In addition, the use of hot-dip galvanized steel grating is also related to the industry. The chemical industry has a large corrosion, so the service life of hot-dip galvanized steel grating is correspondingly discounted. There are also differences between indoor and outdoor use. In the range of pH 6 ～ pH 12.5, a stable protective film is formed on the surface of the zinc coating, which has good corrosion resistance under different service environments
