4×25F-FC

The wire rope consists of four strands, each twisted from 25 individual wires in a specific configuration (where "F" typically denotes a Filler construction and "Fi" indicates a Warrington-Seale or similar shaped-strand design). This structure generally employs a Lang's lay or similar technique; by increasing the rope lay length and reducing the strand lay angle, the torsional moments between the rope and the strands are effectively balanced, resulting in non-rotating (torque-resistant) characteristics.

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.
