Built to Last — Why 3mm Matters

Most garden edging products are between 1.6mm and 2mm thick, which can bend or lose shape over time.

At 3.0mm thickness, this edging provides superior strength and durability, keeping your garden lines sharp and defined even under pressure.

Designed for NZ Conditions

Corten steel forms a stable, protective rust layer that prevents deeper corrosion. This means your edging not only looks better over time but also lasts significantly longer than untreated steel.
