The Difference Between Electric Galvanized Wire and Hot-dip Galvanized Wire

Galvanized steel wire is divided into hot-dip galvanized wire and cold-galvanized wire (also called electric galvanized wire).
Electric galvanized steel wire is decomposed by electrolyte, and the steel wire passes through the electrolyte tank. According to the principle of opposite sex attraction, opposite electrodes are connected to the steel wire and the electrolyte tank respectively, so the zinc molecules will be attracted to the vicinity of the iron wire and stick tightly to the steel wire. Hot-dip galvanized steel wire means that the zinc ingot is melted into the zinc tank at high temperature. When the steel wire passes through the zinc tank, the zinc will stick to the steel wire. After subsequent cooling and drying, the zinc layer will be firmly attached to the surface of the steel wire. This is the process difference between electric galvanized and hot-dip galvanized steel wire.

In addition, there is another difference. The hot-dip galvanized steel wire is dipped in the heated and melted zinc solution. The production speed is fast, the coating is thick, but the color is dark. Galvanized wire lasts for decades. The coating of hot-dip galvanized wire is thicker, generally 30-60 microns, and the height can reach 300 microns. The galvanized layer is thick, and the anti-corrosion ability is high. Cold galvanized wire (also known as electric galvanized wire) is to gradually attach zinc to the metal surface through the current in the electroplating tank. The production speed is slow, the coating is uniform, the zinc layer is thin, the appearance is bright, the corrosion resistance is poor, the use time is short, and it is easy to rust. Because the coating of electric galvanized wire is relatively thin, generally within 5-30 microns, the anti-corrosion time will be relatively short, and it is generally used indoors.
The above is the difference between electric galvanized steel wire and hot-dip galvanized steel wire.
