The difference between hot-dip galvanized wire and cold-dip galvanized wire

Galvanized wire is pided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire). The difference is: hot-dip galvanizing is dip-plated in a molten zinc solution with high production speed and thick but uneven coating. The color is darker, consumes a lot of zinc metal, and forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can be maintained for decades in an outdoor environment.

According to electro-galvanized wire manufacturers, cold galvanizing (electro-galvanizing) is to gradually coat zinc on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, and the thickness is thin, usually only 3-15 microns. Bright, poor corrosion resistance, usually rusting in a few months. Compared with electro-galvanizing, hot-dip galvanizing has a lower production cost and has a smaller impact on the environment than electro-galvanization.

Application range of hot-dip galvanizing: According to electro-galvanized wire manufacturers, hot-dip galvanizing has better protection performance than electro-galvanizing due to the thicker coating, so it is an important protective coating for steel parts used in harsh working environments.
