Upgrade your landscaping with premium 3mm thick Corten steel edging designed to hold its shape and improve in appearance over time. Unlike thinner alternatives, this heavy-duty edging delivers clean lines, durability, and a professional finish that lasts for years.
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.

No special tools required.
Simply position the edging, secure it in place with joiners and supplied bolts, and backfill. The rigid structure makes it easy to achieve straight, professional-looking results with minimal effort.
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.
Will it rust through?
No — the rust layer acts as protection, preventing further corrosion.
Is it safe to handle?
Yes — the folded top edge reduces sharpness compared to raw steel edges.
Can it be shaped?
Best suited for straight lines or not suitable for curves.
