4×31WS-FC

It is constructed from four strands, with each strand consisting of 31 individual steel wires. The "WS" designation indicates a Warrington-Seale hybrid lay structure. This design optimally combines the high strength of the Seale pattern with the flexibility of the Warrington pattern, resulting in a compact structure that offers high breaking strength alongside excellent fatigue and wear resistance.

The fiber core (typically made of natural or synthetic fibers, such as polypropylene/PP) imparts superior flexibility and shock-absorbing (cushioning) properties to the rope while reducing its overall weight, making it ideal for suspended platform lifting systems that involve frequent bending and movement over drums.

Wire ropes for suspended platforms typically undergo a full galvanization process, resulting in a dry, smooth surface that effectively resists corrosion caused by rain and humidity in outdoor environments.
