Custom sizes and specific tensile strengths available upon request.

Main Features

High Strength Steel Core (IWR)

Steel core structure improves load capacity by 10%–15% compared to fiber core ropes, ensuring higher safety in heavy-duty lifting.

1570–2160 MPa Tensile Strength

Wide strength range supports extreme load conditions with high breaking force and reliable performance.

25% Longer Fatigue Life

Specialized wire drawing process enhances cyclic bending performance, extending service life by up to 25%.

Optimized Lubrication System

Filled with Grade A lubricant to reduce internal friction by over 20% and effectively prevent internal corrosion.

Wear-Resistant Multi-Strand Design

6×25–6×55 constructions improve surface contact and reduce abrasion, ideal for high-frequency operations.

Enhanced Corrosion Protection

Galvanized surface increases corrosion resistance by 30%–50%, suitable for humid and marine environments.

Stable Under Dynamic Loads

Maintains structural stability under multi-load and high-speed working conditions, reducing deformation risk.

Wide Diameter Range (16–100 mm)

Supports diverse applications from general lifting to heavy industrial use with full customization options.

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.

Steel Wire Rope Production Process

We maintain 100% traceability and quality consistency by controlling the entire supply chain in-house:

1. Wire Rod Selection: Utilizing premium high-carbon steel for maximum base strength.

2. Advanced Drawing: Precision drawing to achieve exact diameter tolerances.

3. Lead Patenting/Heat Treatment: Optimizing the molecular structure for superior fatigue resistance.

4. Galvanization: High-grade zinc coating for extreme corrosion protection.

5. Secondary Drawing: Enhancing tensile strength and surface smoothness.

6. Stranding & Closing: Sophisticated geometry control for high fill factors and stability.

7. Pre-tensioning: Eliminating structural stretch to ensure precision length and load stability.

8. Final Packaging: Heavy-duty seaworthy protection for global transit.
