Large roll galvanized wire is simply galvanized iron wire, usually used wire is often visible, because iron is very easy to be corroded and rusted, so it is necessary to put a layer of other not easy to rust metal plating in the outer layer, to achieve the effect of corrosion resistance and rust resistance, the effect of zinc can do more. Therefore, many customers often require hardware factories to produce galvanized iron wire, which requires the use of galvanized iron wire equipment.

The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc solution, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the gravitational attraction between the atoms is relatively small.
