Wire rope is a type of
cable which consists of several strands of metal
wire laid (twisted) into a
helix. The term cable is often used interchangeably with wire rope. However, in general, "wire rope" refers to diameter larger than 3/8 inch (9.52 mm). Sizes smaller than this are designated cable or cords. Initially
wrought iron wires were used, but today
steel is the main material used for wire ropes.
