', Electro-galvanizing is to use electrolysis equipment to remove oil, pickle, and then put the pipe fittings into a solution composed of zinc salts, and connect the negative electrode of the electrolysis equipment. Place a zinc plate opposite the pipe fittings and connect it to the positive electrode of the electrolysis equipment. When the power is turned on, a layer of zinc will be deposited on the pipe fittings by using the directional movement of current from the positive pole to the negative pole. Cold-plated pipe fittings are processed first and then galvanized.

' ' Electro-galvanized steel sheets are mainly used for electrical, electronic devices, chassis, movements and other parts.
