Wire rod is used for cold drawing steel wire and then phosphating coating. The heavier the phosphating film, the higher the quality, and then the steel wire rope is twisted with phosphating coated steel wire.
The greater the weight of phosphating film, the longer the fatigue life. The service life of 30-35g/m2 phosphating coated wire rope is longer than that of 15-20g/m2. It is hoped that more enterprises will produce phosphating coated wire ropes.
