Our country industry chooses the low carbon steel with good quality as raw material, and then produces the quality galvanized iron wire by drawing, galvanizing and other processes. Now the production technology of galvanized iron wire products can be divided into hot plating and electroplating two kinds of methods. No matter which one is chosen, it should be carried out in accordance with the corresponding operating specifications, so as to better ensure the production of good products. For key and important parts with tensile strength greater than 1034mpa before plating, the stress should be released at 200±10℃ for more than 1 hour and 140±10℃ before plating.

When pickling, the galvanized wire needs to be slowly put into the cylinder to avoid liquid splashing on the body. Protective glasses should be worn in the pickling process to prevent acid splash out and hurt people. Pay attention to safety when receiving the line operation, the line tray needs to be lightly placed, stacked neatly, not more than 5 disks. No matter what kind of auxiliary materials are used, galvanized wire drawing must comply with national regulations, otherwise it is not allowed to be used.
