7×7 Wire Rope

Enhance your marine and industrial systems with our 7×7 Stainless Steel Wire Rope, crafted from AISI 316 Marine Grade Stainless Steel for superior strength, flexibility, and corrosion resistance. The 7×7 construction—comprising 7 strands with 7 wires each—offers a balanced blend of strength and moderate flexibility, making it ideal for applications where both tension and bending are required.

Whether used in marine rigging, architectural railings, hoisting systems, or cable balustrades, this wire rope provides reliable, long-lasting performance in even the harshest environments.

Key Features of 7×7 Wire Rope

1. Strand Construction and Flexibility of 7×7 Wire Ropes

The 7×7 wire rope configuration consists of 7 strands with 7 wires each. This design offers moderate flexibility and excellent torsional balance, making it suitable for both static and light dynamic marine applications.

2. Core Types and Structural Support of 7×7 Wire Rope

Available with either a fiber core or independent wire rope core, the 7×7 rope maintains its shape under load. The IWRC variant improves resistance to crushing and provides greater durability in mechanical systems.

3. Material Composition and Corrosion Resistance

Manufactured from galvanized or stainless steel, the rope withstands rust, salt spray, and UV exposure. Stainless steel options offer superior corrosion resistance, especially when installed in open-deck or coastal conditions.

4. Load Performance and Tensile Strength of 7×7 Wire Ropes

7×7 wire rope provides a strong balance between tensile strength and handling. It’s ideal for medium-load applications such as control cables, balustrades, and lifting lines where flexibility and reliability are both essential.

5. Application Suitability

This wire rope is commonly used for marine control cables, railing systems, standing rigging, and winch lines. It fits well in situations that require some flexibility but not the fine bending radius of 7×19 rope.

6. Diameter Range and End Fitting Options of 7×7 Wire Rope

Available in diameters from 1 mm to 10 mm, the rope can be fitted with thimbles, ferrules, swaged terminals, or clamps. These options support both permanent installations and temporary rigging tasks on board.

7. Handling and Installation Ease

Crews find the rope easy to cut, terminate, and install using manual or hydraulic tools. Its medium stiffness makes it simple to route through blocks, pulleys, and tight control channels.

8. Compliance and Certifications

All 7×7 wire ropes comply with ISO 2408 standards and are approved by maritime authorities such as DNV, ABS, and Lloyd’s Register. They meet safety guidelines for marine rigging, control systems, and onboard infrastructure.
