The difference between cold galvanizing and hot galvanizing process of hook mesh

Galvanized hook mesh is divided into hot-dip galvanized hook mesh and cold galvanized hook mesh, the difference between the two is: hot-dip galvanized is in hot liquid melting zinc dipping, production speed, coating thickness, but not uniform, the market allows the smallest thickness of 45 microns to 300 microns.
Hot-dip galvanized wire mesh is heated at high temperature to put it into liquid zinc, under the action of high temperature and catalyst, a series of chemical reactions will occur, and finally make the surface of the wire mesh with a thick zinc layer. The hook mesh obtained by hot-dip galvanizing is bright, very beautiful, and has strong corrosion resistance.
Cold galvanized wire mesh is to put the workpiece directly into the zinc liquid, and then use the principle of electrolyte to make zinc attached to the surface of the wire mesh, cold galvanized wire mesh surface zinc layer is relatively thin, compared with hot dip galvanized color is relatively bright, but a long time may rust.
The surface color of cold galvanized hook mesh and hot-dip galvanized hook mesh is silver-white, almost no difference, but look carefully you will find that the color of electric galvanized hook mesh is brighter, the color of hot-dip galvanized hook mesh is dark, the zinc layer of hot-dip galvanized hook mesh is thicker than that of electric galvanized hook mesh, the difference is made from product characteristics, the corrosion resistance of electric galvanized hook mesh is relatively poor, generally used for 5-7 months, Rust will appear on the surface. Hot-dip galvanized hook mesh has been used for 10 years, and the surface does not rust. The difference in the price of the hook net, from the manufacturer’s hook net quotation can be seen, the general hot-dip galvanized hook net is higher than the price of electric galvanized hook net.
