316 A4 Stainless Steel Wire Rope 0.8mm-12mm LIFTING METAL CABLE 7x7-7x19

A 7×7 rope consists of 7 bundles of 7 individual wires each (49 wires total). It is stiffer and holds its shape well, making it suited to straight tensioned runs such as balustrade infill wires or trellis cables. A 7×19 rope has 7 bundles of 19 wires each (133 wires total), giving it significantly more flexibility. Choose 7×19 when the cable must bend around a pulley, pass through a block, or flex repeatedly in service.

316 stainless (also designated A4 under ISO 3506) contains 2–3% molybdenum, which substantially improves resistance to chloride-induced pitting and crevice corrosion. In coastal, marine, or high-humidity environments where 304 stainless or galvanised cable would show surface rust or pitting within months, 316 maintains its appearance and structural integrity for years with minimal maintenance.

For residential deck and stair balustrades, 3 mm and 4 mm diameters are the most common choices, balancing a slender visual profile with adequate tensile strength for code-compliant installations. Larger spans or higher-load applications may call for 5 mm or 6 mm. Always check your local building code for minimum breaking load requirements and apply the specified safety factor before finalising your diameter selection.

This rope is suitable for light-to-medium lifting, lashing, and rigging tasks. For any safety-critical lifting application, you must verify the minimum breaking load for the specific diameter and construction you select, then apply the appropriate working load limit safety factor (typically 5:1 or as required by your jurisdiction). Do not use wire rope for overhead lifting without confirming it meets the relevant load rating standard for your application.

Standard swage terminals (stud, fork, eye, and jaw types), Nicopress or oval ferrules, wire rope clips (bulldog grips), and thimbles are all compatible — provided they are sized to match the diameter you order. For marine and outdoor use, select 316 stainless fittings to avoid galvanic corrosion at the termination point. Avoid mixing 304 fittings with 316 rope in salt-water environments.

Apply two wraps of electrical tape or self-amalgamating tape on either side of the cut point before cutting. Use an angle grinder with a thin cutting disc, or purpose-made wire rope cutters rated for the diameter. Avoid bolt cutters on larger diameters as they tend to crush and splay the strands. After cutting, immediately apply a dab of clear silicone or a heat-shrink end cap to prevent strand separation during handling and installation.

Standard cut lengths available are 1 m, 2 m, 5 m, 10 m, 20 m, 50 m, 100 m, and 200 m. Select the length closest to your requirement from the variant options above. If you need a length not listed, please contact us before ordering and we will advise on availability.
