6×31 Class Round Strand Wire Rope

6×31 Class Round Strand Wire Rope

Product Introduction:

Our 6×31 Class Round Strand Wire Rope features a Warrington‑Seale (WS) strand design – six strands each composed of 31 wires, with the outer layer formed by alternating thick and thin wires. This configuration, compared to the 6×26WS, incorporates more wires per strand, resulting in superior flexibility and exceptional bending fatigue resistance, while still maintaining a smooth external surface that minimises wear on sheaves and drums. The WS lay also provides excellent resistance to crushing and distortion, making this rope particularly suitable for applications involving frequent bending, multi‑layer spooling, and high‑cycle lifting operations.

Manufactured in full compliance with GB/T 20118‑2017, the rope is offered with two core options to match your operational priorities:

*FC (Fibre Core) – delivers outstanding shock absorption, internal lubrication, and flexibility, ideal for dynamic shipboard tasks.

*IWRC (Independent Wire Rope Core) – enhances crush resistance and overall breaking strength, recommended for heavy‑duty hoisting and winching where stability under load is critical.

Marine Applications:

*Mooring lines and breast ropes.

*Tugboat towing springs and stern lines.

*Crane hoist and derrick cables.

*Anchor pendants and mooring tails.

*Offshore platform winch and riser tensioning lines.

Why Choose 6×31WS?

1.The high wire count per strand grants excellent flexibility, reducing bending stress and extending rope life in tight sheave systems.

2.The WS construction offers a balanced trade‑off between abrasion resistance and fatigue endurance – outperforming filler‑wire designs in cyclic loading scenarios.

3.Galvanised finish ensures long‑term durability in harsh marine atmospheres.

4.Every rope is proof‑tested and certified, with custom lengths, end fittings, and packaging available to meet vessel‑specific requirements.
