Commonly used wire rope varieties are manganese phosphide coated wire rope, galvanized wire rope, stainless steel wire rope or plastic coated wire rope. The manganese phosphating coated wire rope produced by patented technology has the longest service life and is the most advanced technology in the wire rope manufacturing industry in the world. Manganese phosphating coating can greatly improve the wear resistance and corrosion resistance of wire rope surface, and the fatigue life of manganese phosphating coated wire rope is 3-5 times that of smooth wire rope. With the research of wear-resistant phosphating solution, there is still the possibility of further improvement. According to the current market price of phosphating coated steel wire rope, the daily average cost of manganese phosphating coated steel wire rope is only about one third of that of smooth steel wire rope. Manganese phosphating coated steel wire rope is an upgraded product of smooth steel wire rope for reference only.
