Do you know galvanized wire?

Galvanized wire is made of high-quality mild steel wire rod. It is made of high-quality low-carbon steel, processed by drawing, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electro galvanized wire).Galvanized wire has good toughness and flexibility, the maximum amount of zinc can reach 300 g / square meter. With zinc coating thickness, corrosion resistance and other characteristics.
Galvanized wire is divided into hot galvanized wire and cold galvanized wire the difference is:
Hot-dip galvanizing is immersed in a heated, molten zinc solution to produce a high-speed coating that is thick but non-uniform. The minimum allowable thickness for the market is 45 microns and up to 300 microns. Darker colors, zinc metal consumption and the formation of the base metal infiltration layer, corrosion resistance, hot galvanized outdoor environment can be maintained for decades.
Cold galvanized is in the plating tank through the current unidirectional zinc plated metal appearance, the production speed is slow, uniform coating, the thickness is thin, usually only 3-15 microns, the appearance of bright, poor corrosion resistance, Generally a few months will rust.Relative to hot-dip galvanizing, electroplating zinc production costs lower.
Cold galvanized and hot dip galvanized difference:
Cold galvanized and hot-dip galvanized difference is the amount of zinc, you can identify them from the color, cold galvanized hair shiny silver white with yellow. Hot dip galvanized hair white.
Galvanized wire can be divided according to its purpose:
Building tied with wire is 22 # (0.71mm), low prices, its characteristics of good flexibility, not easy to break, is the construction industry, one of the most ideal tie wire, mainly using low zinc cold-plated iron wire. The main use of low-zinc cold-plated iron wire.
