Galvanized wire is divided into hot galvanized wire and cold galvanized wire (galvanized wire). Hot-dip galvanizing is carried out by immersion plating in a heated and liquefied zinc bath. The production speed is fast and the coating thickness is thick but not uniform. The amount of zinc allowed in the market is 40-60g, and can reach more than 300g. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing in the outdoor environment can be maintained for several decades. Cold galvanizing (galvanizing) is to make the zinc gradually plated on the metal surface through the unidirectionality of the current in the plating tank, the production speed is slow, the coating is uniform, the thickness is thin, usually only 20g, the appearance of light, poor corrosion resistance, generally several The month will rust. Relative hot-dip galvanizing, galvanized steel production costs are lower. The difference between cold galvanized and hot galvanized is the difference in the amount of zinc, they can be identified from the color, cold galvanized color shiny silver white with yellow. Hot-dipped galvanized shiny white.
