Galvanised Straining Wire

💪 Built for load‑bearing support

This wire is heavy‑duty galvanised steel, meaning it’s designed to carry tension without stretching. In a polytunnel, that matters — irrigation pipes, shade netting, and Tensar netting all add weight over long runs. Galvanisation prevents rusting in humid environments, giving it a long working life.

🌱 Core polytunnel function

It’s installed down the length of the tunnel, 

usually fixed to end frames or ridge points. Its main roles include:

• Supporting overhead LDPE irrigation pipe

• Carrying Tensar netting for crop support

• Acting as a structural line for shade netting or internal accessories

This makes it one of the “hidden essentials” of a well‑equipped tunnel.
