Galvanized metal mesh takes a long time for the galvanized mesh to rust. This type is carbon steel that has been galvanized or coated with a thin layer of zinc. Zinc acts as a barrier to prevent oxygen and water from reaching the steel, so it is corrosion-resistant. Even if the galvanized layer is scraped off, it can continue to protect the nearby area Cathodic protection and the formation of a zinc oxide protective layer. Like aluminum, zinc is highly reactive to oxygen in the presence of moisture, and the coating prevents further oxidation of iron in steel. If you need architectural wire mesh, please choose the galvanized metal mesh.
Galvanized Metal Mesh
Hot-dip galvanizing is an effective form of metal corrosion protection, especially for installations in the architectural industry as architectural wire mesh.
The galvanizing process is as follows:
The steel wire is immersed in 500c zinc liquid, and the zinc layer has been attached to the surface of the steel element as a rust inhibitor. Of course, the quality of the zinc used here is also very important. The thickness of the liquid zinc coating varies. Due to the use of high-quality zinc, barbed wire fences can be used for many years.
Under normal conditions, galvanizing can provide corrosion protection for as architectural wire mesh cores for up to 50 years, even longer in arid areas. However, in rural, industrial, and marine environments, pollutants such as herbicides, sulfides, and high salt content can rapidly increase the corrosion rate of zinc and reduce life offenses. The corrosion of the galvanized mesh as architectural wire mesh is also affected by many other factors, such as rainfall, humidity, temperature, and the thickness of the galvanized layer. For example, in dry conditions, heavy rainfall will increase the corrosion rate, but in a highly corrosive marine or industrial environment, it can significantly reduce the corrosion rate.
