Key Features
1770 N/mm² High Tensile Grade: High-grade steel wire drawing delivers consistent breaking strength and long service life under high-tension loads.
Balanced 7x7 Multi-Strand Design: Provides superior flexibility compared to 1x19 structures while maintaining higher rigidity than 7x19, making it ideal for pulley systems and static guy lines.
Convenient Coil Packaging: Packaged in compact, tightly wound coils for hassle-free handling, storage, and precise length cutting on site.
Smooth & Uniform Finish: Precision strand closing ensures exact outer diameter tolerance, minimizing friction against sheaves, guide tubes, and fasteners.
Key Applications
Control Cables & Automotive Rigging: Brake cables, throttle lines, clutch assemblies, and mechanical push-pull controls.
Agricultural & Vineyard Trellising: High-tension support wire for fruit orchards, green wall lattices, and greenhouse shading structures.
Safety Netting & Guardrail Cables: Protective mesh boundary cables, fall-protection perimeter lines, and industrial safety lanyards.
General Industrial Binding & Guy Lines: Structural tie-downs, antenna guy wires, canopy stays, and general material securing.
