Why Choose 6x19S Structure?

The Seale (S) construction features larger outer wires compared to standard 6×19. This provides a larger contact surface, significantly increasing abrasion resistance and service life in harsh environments like oil drilling and mining. The IWRC core ensures the rope maintains its shape even under extreme drum crushing.

6×19 Structure for Versatile Use

Multiple constructions (6×19+FC/IWR/IWS, 6×19S/W) support lifting, hoisting, drilling, and marine applications.

1570–2160 MPa High Tensile Strength

Delivers strong breaking force and reliable performance under heavy-duty and extreme load conditions.

Wide Diameter Range (9–46 mm)

Flexible specification coverage for light, medium, and heavy industrial applications.

Steel Core Option for Heavy Loads

IWR/IWS structures improve load capacity and stability, ideal for cranes, drilling rigs, and bridge tensioning.

Optimized for Dynamic & High-Speed Operation

Stable structure reduces vibration and deformation in high-speed and variable load environments.

Wear-Resistant & Long Service Life

6×19 compact strand design enhances abrasion resistance for frequent use scenarios.

Galvanized for Corrosion Resistance

30%–50% improved resistance in marine, humid, and harsh environments.

Certifications

Juli Sling steel wire rope meets API, GOST, and ISO standards, reflecting our commitment to global quality benchmarks, strict manufacturing control, and dependable performance in demanding lifting and industrial environments.

Applications

• Marine & Offshore: Mooring lines, towing hawsers, and offshore crane ropes.
• Oil Drilling: Main drilling lines and winch ropes for oil rigs.
• Construction: Heavy-duty crane hoist ropes and wire rope slings.
• Mining: Conveyor systems and hoisting operations in open-pit mines.
