Application scope of galvanized steel wire rope

Galvanized steel wire ropes can be used for bundling, towing, strapping of vehicles and ships, shipping, offshore oil exploration, aircraft control, marine fishing, trawling, fixed nets, rolling nets and other fisheries. In the past, the core of galvanized steel wire rope was usually made of sisal and jute, but because these materials tend to absorb acid, alkali, seawater and other corrosive substances during work, the inner steel wire was corroded and broken early. Polypropylene has been used as the core. The twisting of the galvanized steel wire rope is the same as that of the ordinary round strand steel wire rope, but according to the working conditions of the steel wire rope, the thickness of the zinc layer of the raw steel wire is different: the thickness of the galvanized steel wire rope of 0.2～5.0mm can be divided into 3 Group: The amount of zinc on the thin coating group is 15～135g/m2, used for mild corrosion conditions; the amount of zinc on the middle coating group is 60～200g/m2, used for medium corrosion conditions; the zinc content on the thick zinc coating group is 75 ~260g/m2, used in severe corrosive conditions. In order to ensure the quality of the steel wire rope, the surface of the steel wire galvanized layer should be smooth, complete, uniform and firm. When the galvanized steel wire is spirally wound on a core rod with a diameter of 5 or 10 times the diameter of the steel wire, the zinc layer should not fall off or crack.
