    • Wire rope is designated by three numbers which denote diameter, number of strands and wires in each strand.

    • Wire rope 40 mm 5 x 16 indicates that the wire rope has 40 mm diameter and contains 5 strands each having 16 wires.

    • The wire rope 6 x 37 (18/12/6/1) indicates that the wire rope has 37 wires and 18 are in outer layer, 12 in second layer, 6 in third layer and 1 in innermost layer, they determine class of wire ropes.
    (6 x 37) indicates class of wire rope which contains 6 strands and each strand has 37 wires.
