The structure of wire rope is much more complicated, and there are dozens of commonly used ones, such as 35 * 7 or 6 * 36WS structure. Generally, the lay length of the wire rope is not more than 7 times, and the wire rope can be bent and deformed around the pulley. The wire rope is divided into hemp core and steel core. Commonly used steel wire ropes include phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope or plastic coated steel wire rope, which are used in atmospheric environment. Manganese phosphating coated steel wire rope produced by patented technology has the longest service life, and the fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope. In severe corrosive environment, the hot dip galvanized-phosphating double-coated steel wire rope with outstanding anticorrosion ability is preferred, and the smooth steel wire rope is being eliminated.
Prestressed steel strand and wire rope adopt different national standards for reference only.
