8、ce, fatigue resistance, shape collapsing resistance and corrosion resis- tance comparing with the general wire ropes and so JIS G 3546 was established in 1993. 1 Scope This Japanese Industrial Standard specifies general wire ropes with profile wires to be used for machines, elevators, construction w
