Does the hoisting wire rope of Guizhou steel rope have manganese wear-resistant protective coating?

Phosphating coated steel wire rope is an invention patent of China, which can be retrieved from the website of the Patent Office. This patent belongs to a natural person, not any wire rope manufacturer. Therefore, any enterprise that produces manganese phosphating coated steel wire rope can legally produce it only after obtaining patent permission. As for whether the steel wire rope of your rope has manganese phosphating coating, the steel wire rope produced at present should have no manganese wear-resistant protective coating, and it is unknown whether it will be produced in the future. It is recommended to call your rope sales department directly to ask.

Manganese phosphating coated wire rope is the only wire rope with wear-resistant protective coating in the world at present. The film weight of manganese phosphating film is the most important technical index. The film weight of manganese phosphating film is mostly 15-30g/m2. If you buy manganese phosphating coated steel wire rope, you must check the film weight of phosphating film after arrival to prevent illegal traders from passing smooth steel wire rope off as manganese phosphating coated steel wire rope. Manganese phosphating coated steel wire rope has longer fatigue life and lower unit use cost, and is an upgraded product of various smooth steel wire ropes.
