Hot dip galvanized iron wire is made of wire rod (currently 1006, TS06, Zhongyang Q195, Jiujiang Q195, etc. in China) through drawing, heating, re-drawing, and finally coated with zinc by hot-dip coating process. The amount of zinc applied is generally controlled in the range of 30 g/m^2 to 290 g/m^2 depending on the requirements of the use environment. Since the products produced by the hot-dip galvanizing process have a long-lasting anti-corrosion period and a wide use environment, the hot-dip galvanized iron wire is widely used in various fields such as heavy industry, light industry, agriculture, etc. in the form of net, rope and wire.
