The coatings include galvanized, aluminum-plated, nylon, or plastic coatings. Galvanized steel is divided into thin-coated steel wire that is drawn first and thick-coated galvanized steel wire that is drawn later. The mechanical properties of thick-coated steel wire rope are lower than those of smooth steel wire rope, and it should be used in severely corrosive environments. Aluminum-plated steel wire rope is more resistant to corrosion, wear, and heat than galvanized steel wire rope. It is mainly used in trawling fishing boats and mines containing hydrogen sulfide. It is produced by the method of plating first and then drawing. Steel wire ropes coated with nylon or plastic are divided into coated ropes and coated stranded ropes. The former is used for static cables, while the latter is used for mobile cables.
