6×65 Class Round Strand Wire Rope

6×65 Class Round Strand Wire Rope

Product Introduction:

Designed to meet the rigorous demands of modern marine engineering, offshore operations, and heavy‑lift applications, our 6×65 Class Round Strand Wire Rope (construction code 6×65FNS) delivers an outstanding combination of strength, flexibility, and fatigue resistance. The “FNS” designation signifies a compound‑laid, non‑slip strand configuration with a layered wire arrangement of (1+6+6F+12‑20+20) – totalling 65 wires per strand. This multi‑stage twisting process creates a mixed point‑and‑line contact pattern among the wires, which significantly improves the rope’s resistance to crushing, abrasion, and dynamic loading compared to conventional point‑contact designs. The result is a rope that excels in multi‑layer drum winding, high‑cycle lifting, and severe bending over sheaves.

Manufactured strictly in accordance with GB/T 20067‑2006 (and compliant with international standards such as ISO 2408, ASTM A1023, EN 12385, and JIS G 3525), this rope is offered in two core options to suit different operational profiles:

*FC (Fiber Core) – provides inherent elasticity and shock absorption, reducing peak tensile spikes and extending rope life in moderate‑duty cycles. The fibre core also enhances flexibility, making it ideal for applications with frequent bending.

*IWR (Independent Wire Rope Core) – features a full metallic core that increases the rope’s metallic cross‑sectional area, delivering superior crush resistance and higher breaking loads. This configuration is preferred for heavy‑lift, high‑frequency, and harsh‑environment duties where maximum tensile capacity is paramount.

Technical Specifications：

The rope is available with various surface finishes – bright, galvanized, or specially lubricated – to provide excellent corrosion resistance in seawater and humid atmospheres. It can be tailored to meet specific customer requirements, including custom lengths, reeling drums, and end fittings (such as sockets, thimbles, or swaged terminals).

Typical Applications Include:

*Ship‑to‑ship mooring and towing hawsers.

*Offshore platform cranes and pedestal cranes.

*Floating production storage and offloading (FPSO) units.

*Shipbuilding gantry and floating cranes.

*Dredging and underwater salvage operations.

*Aerial ropeways and heavy‑duty industrial hoists.

Every production batch undergoes rigorous quality control – from raw material inspection (wire rod analysis) through to final proof‑loading and dimensional checks. Our ropes can be supplied with classification society certifications from ABS, LR, CCS, BV, DNV, and CE, ensuring full traceability and compliance with global marine standards.

With its advanced FNS strand geometry, robust metallic core option, and adherence to the most stringent international requirements, the 6×65 Class Round Strand Wire Rope is the trusted choice for marine professionals who demand uncompromising performance, longevity, and safety in the world’s toughest operating environments.
