manganese phosphating coated elevator wire rope is a patented technology in China, which is twisted with manganese phosphating steel wire. Manganese phosphating technology is very mature and low in price. The sales price of manganese phosphating coated elevator wire rope is only slightly higher than that of smooth elevator wire rope, and its fatigue life is 3-4 times that of smooth elevator wire rope. Please compare and verify it through fatigue test.
to sum up, manganese phosphating coated elevator wire rope is more cost-effective. My personal opinion is for reference only.
