The main varieties of wire rope are manganese phosphating coated wire rope, galvanized wire rope, stainless steel wire rope, plastic coated wire rope and ropeway wire rope. Phosphating coated wire rope is a patented technology in recent two years. After manganese phosphating or zinc-manganese phosphating treatment, the wear resistance and corrosion resistance of steel wire surface are improved in an all-round way, and it is not easy to wear and rust. The fatigue life is three times that of smooth steel wire rope, and the cost performance is higher.
