Why Do Some Shadeport Cables Rust Faster Than Others?

Fibre Core vs Steel Core Wire Rope

Although shade-netting is the most visible part of a shadeport, the tensioning cable is one of the most important components of the entire installation. The cable runs around the perimeter of the shade-net and is responsible for keeping it evenly tensioned and securely attached to the structure. A high-quality cable helps maintain the shape of the shade-net, reduces unnecessary movement in windy conditions, and contributes significantly to the overall lifespan of the installation.

Why Some Galvanised Cables Rust Faster

Not all galvanised wire ropes offer the same level of corrosion resistance. Although two cables may appear almost identical from the outside, the quality of the galvanising process, the manufacturing standards, and the materials used can have a significant impact on how well the cable performs outdoors. A higher-quality galvanised cable is designed to provide better long-term protection against moisture and the elements, helping to extend the lifespan of the shadeport.

Recently we attended a repair where the shade-net had been manufactured larger than the supporting structure. Even before the cable was tensioned, the net sagged considerably. The existing cable had also suffered extensive corrosion and required replacement. Once the correctly sized cables were installed and the structure assessed, the shadeport performed as intended.
