Clear PVC Coated Steel Wire Rope Metal Cable Rigging 0.38mm-12mm Heavy Duty

The construction number describes how the wire strands are arranged. 1×7 has one core wire surrounded by 6 outer wires — it is the stiffest and least flexible, suited to fixed, straight runs. 7×7 has 7 groups of 7 wires each, offering a balance of flexibility and tensile strength — the most common choice for balustrade and general rigging. 7×19 has 7 groups of 19 wires, making it the most flexible and best suited to dynamic applications such as sailboat rigging, pulleys, and frequently bent cable runs.

For residential balustrade infill cables, 3mm–4mm diameter in 7×7 construction is the most common specification. For longer spans (over 1.5m between posts) or higher-load applications, 4mm–6mm is recommended to limit deflection. Always check your local building code for minimum cable diameter and maximum spacing requirements. For marine stanchion lifelines, 4mm–6mm 7×7 or 7×19 is typical.

Yes. The stainless steel core provides inherent corrosion resistance, and the clear PVC sheath adds an additional barrier against moisture, salt spray, and UV exposure. This combination makes it suitable for garden trellises, outdoor clotheslines, marine deck hardware, and coastal balustrades. For fully submerged or continuous saltwater immersion applications, confirm the stainless steel grade with us before ordering.

Compatibility depends on the construction type. 1×7 rope works best with swaged end fittings, eye terminals, and fork terminals that suit rigid cable. 7×7 and 7×19 ropes are compatible with swaged fittings, aluminium oval ferrules (crimped with a hand or hydraulic press), wire rope clips (bulldog grips), and thimble-and-shackle assemblies. Always match the fitting bore to the wire diameter — for PVC-coated rope, measure the coated OD and select fittings accordingly, or strip the PVC at the termination point.

The rope is sold in the pre-cut lengths listed in the variant options (1m through 1000m). Select the length closest to your requirement. For cutting on-site, use dedicated wire rope cutters or an angle grinder with a cutting disc — standard bolt cutters may crush and fray the strands. After cutting, apply heat-shrink tubing or a dab of clear silicone to the cut end to prevent the PVC from peeling and the strands from unravelling.

As a general guideline, the minimum bend radius for wire rope is approximately 10–12× the rope diameter for 7×7 construction and 8–10× for 7×19 construction under working loads. For 1×7 (rigid) construction, avoid tight bends entirely — it is designed for straight or very gently curved runs. Exceeding the minimum bend radius accelerates fatigue and reduces the effective breaking load. For pulley or sheave applications, select a sheave diameter of at least 16× the rope diameter.

Measure the total run length of each horizontal or vertical wire, then multiply by the number of wires in your grid. Add approximately 200–300mm per termination point for threading through fittings and tensioning. For a typical 2m × 3m trellis with 5 horizontal wires, you would need approximately 5 × (3m + 0.5m allowance) = 17.5m — rounding up to a 20m spool is practical. Ordering a single longer length and cutting on-site reduces joins and improves appearance.
