Electro galvanizing shaft wire direct is in the electroplating 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 hot dip galvanizing, electric galvanizing has lower production cost. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanized shiny hair white.

Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.
