ZAM® Steel Edging Lengths

Developed using the latest Japanese technology, ZAM® was originally engineered by the automotive industry to endure the harshest of weather conditions.

Formboss has taken this unique product and adapted it to suit garden edging applications. The resulting product is a heavy-duty steel edging with a 15-year Structural Guarantee. Formboss ZAM® Steel Edging vastly outperforms Galvanised Steel in all facets. It has superior strength, durability and corrosive properties; comparable only to Stainless Steel, however at a significantly lower price point.

The ZAM® coating is a specially developed blend of Zinc, Aluminium and Magnesium, straight from the Nishin Steel R&D Laboratory. These metals are bonded to the surface of the steel creating corrosion resistance at least 3 times that of Galvanised steel. The unique coating generates a “Self-Healing” effect, so even cut ends benefit from the anti-corrosion properties.

Our ZAM® Steel Edging gives you a bright and modern finish, perfect for enhancing clean straight lines and beautiful continuous sweeping curves. Its incredible durability makes ZAM® Steel Edging perfect for a wide range of applications which include vegetable & garden beds, tree surrounds and even small retaining walls.
