steel wire plastic coated

    The classification of steel wire rope is mainly based on its strand structure for division, specifically including point contact wire rope, wire contact rope and surface contact wire rope.      Point contact wire rope is characterised by strands of adjacent layers of steel wire helix is not parallel to each other, staggered contact with the same diameter of each layer of steel wire, but the pitch of each layer is not the same, so that the steel wire is point contact. This structure of the wire rope in the load, the contact stress between the steel wire is larger. Typical structure of point contact wire rope includes 6×19+FC(IWR, IWS), 6×37+FC(IWR, IWS), 6×61+FC(IWR, IWS), 6×24+7FC, 18×19+FC(IWS) and so on.      Wire contact wire rope, also known as Xilu type (S), Valintun type (W), filler type (Fi), strands of steel wire thickness is different, all the wires in the strands of the same twisting distance to the wir…
