6×37 Class Round Strand Wire Rope

Product Introduction:

Designed for demanding marine and offshore applications, our 6×37 Class Round Strand Wire Rope complies with GB/T 20118-2017 and delivers exceptional strength, flexibility, and durability. The 6×37 construction (six strands with 37 wires each) offers a balanced combination of fatigue resistance and wear tolerance, making it ideal for mooring, towing, lifting, and cargo handling in saltwater environments.

Performance Highlights:

*High breaking loads ensure safe working under extreme tensions.

*IWR core provides superior crush resistance and greater strength for heavy-duty operations.

*FC core offers excellent flexibility and shock absorption for dynamic loading.

*All ropes are hot-dip galvanized or zinc-coated to resist corrosion, extending service life in marine climates.

*Actual weight tolerance: ±6% (as per standard).

Typical Applications:

Ship mooring lines, tugboat towing springs, crane hoist ropes, anchor cables, and offshore platform winch lines.

Quality Assurance:

Manufactured under strict process control, each coil is proof-tested and certified to meet international safety standards.
