The steel wire rope surface is usually divided into two types: smooth surface and galvanized steel. In the weak corrosive environment and where the wire rope is allowed to be fully lubricated, smooth steel wire ropes are generally used. In the case of corrosive environments and where it is not easy to apply grease to the wire rope surface, galvanized steel wire ropes should be used. The galvanized layer adheres firmly to the surface of the wire and provides cathodic protection. Long corrosion life. Galvanized steel wire ropes are commonly used in marine and other rainy and wet environments.
