Commonly used steel wire rope varieties are phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope or plastic coated steel wire rope. The manganese phosphating coated steel wire rope produced by patented technology has the longest service life. Manganese phosphating film can greatly improve the wear resistance and corrosion resistance of wire rope surface. The fatigue life of manganese phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope. With the research of wear-resistant phosphating solution, it is possible to further improve it. 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 30% 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.
