  • Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.

  • Different hot dip galvanizing process is divided into two categories of annealing outside the line and annealing in the line, hot dip galvanizing is in the hot melt zinc liquid immersion plating, production speed, thick but uneven coating, the market allows Z low thickness of 45 microns, Z high can reach more than 300 microns. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.

  • Large coil galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire. Galvanized wire in the process of smelting there are a lot of need to pay more attention to the place, galvanized wire products in the manufacturing process will experience a lot of process, of which the following galvanized wire annealing is a very important step, this step to the nature of galvanized wire has brought a lot of help.
