Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.

Thus, when zinc is sufficient in a solid melt, the two atoms of zinc and iron disperse with each other. The zinc atoms in the iron matrix are moved into the lattice of the matrix, and the iron elements are gradually formed into alloys. The zinc composition of iron and intermetallic compound FeZn13 in molten zinc solution and the bottom of hot galvanized sheet can be used as zinc slag. The pure zinc layer composed of zinc leaching solution is hexagonal crystal.
