Ag-Steel™ Kiwifruit Product Range

Ag-Steel™ Kiwifruit Product Range

We offer systems that do exactly what they’re designed to do — supporting strong vine growth, protecting your orchard investment, and helping produce the premium kiwifruit New Zealand is known for.

The Ag-Steel™ range is manufactured in New Zealand using pre-galvanised GS310 tube, featuring a Z450 coating with external weld seam zinc repair to ensure coating continuity. With a smooth, consistent surface finish and excellent formability, it’s purpose-built for outdoor, corrosion-prone orchard environments where long-term durability truly matters.

When you choose Ag-Steel, you’re choosing more than a structure. You’re choosing a partner who understands what’s at stake — your land, your yields, and the future of your orchard.

Proudly New Zealand made. Gold-standard sustainably manufactured.
