Construction & Design
6 strands × 7 wires per strand + FC (Fiber Core) or IWRC (Independent Wire Rope Core). The relatively large outer wires provide superior abrasion resistance compared to finer-strand constructions.
Key Features
- Excellent wear resistance due to large outer wire diameter
- High stiffness — ideal for standing rigging and static applications
- Available with FC (Fiber Core) or IWRC (Steel Core) options
- Galvanized and bright (ungalvanized) finish options
- Good fatigue life in moderate bending conditions
- Compliant with GB/T 20118, ISO 2408, and EN 12385 standards
