Coating: galvanized, aluminum, nylon or plastic coating. Galvanized steel wire after the first plating thin coating and galvanized steel wire after the thick coating, the mechanical properties of the thick coating than smooth steel wire rope is somewhat reduced, should be used in serious corrosion environment. Aluminized steel wire rope is more corrosion-resistant, wear-resistant and heat-resistant than galvanized steel wire rope. It is mainly used in fishing trawl ships and mines containing H2S. It is produced by plating before drawing. Nylon or plastic coated wire rope coated rope and coated after two kinds of rope. The former is used for static cables and the latter for moving cables.
