The difference between hot galvanized welded wire mesh and cold galvanized welded wire mesh

The difference between hot Galvanized Welded Wire Mesh and cold galvanized Welded Wire Mesh

1. The galvanizing process is different: the hot-dip galvanized welded Wire Mesh is galvanized under heating, and the welded wire is immersed in the molten zinc solution for a certain period of time. It is very tight, and other impurities or defects are not easy to be left in the middle. It is similar to the melting of two materials together in the plating area, and the thickness of the galvanized welded wire mesh is also called electrogalvanized welded wire mesh. After pickling, put it into a solution containing zinc salt and connect it to the negative electrode of the electrolytic device; place a zinc plate on the opposite side of the welded wire to connect to the positive electrode of the electrolytic device, turn on the power, and use the current to move from the positive electrode to the negative electrode. A layer of zinc will be deposited on the welding wire.

2. Zinc layer thickness is different: cold galvanized welded wire mesh has uniform coating and very thin thickness; hot galvanized welded wire mesh has thicker coating and uneven thickness.

3. The appearance is different: the appearance of cold galvanized welded wire mesh is smooth, smooth, and bright. The hot-dip galvanized welded wire mesh has some unevenness, the color is dark, and the appearance is not delicate and bright.

4, different corrosion resistance Cold galvanized welded wire mesh because of the thin coating, the corrosion resistance is poor. Hot-dip galvanized welded wire mesh has good corrosion resistance because it has a thick coating and forms an infiltration layer with the base metal.

5. Different prices: The price of hot-dip galvanized welded wire mesh is higher than that of cold-galvanized welded wire mesh.
