Thickness of Steel

Gauges Explained (Steel Thickness)

FormBoss® Steel Garden Edging is so much more than a simple edge. Thanks to our vast range, we have an option suited to just about all garden edging needs, from flush edges, to standard lawn edging, steps, retaining walls, tree rings, rooftop gardens and raised garden beds, we have a steel garden edging
system to match.

FormBoss® is offered in three different Gauges, 1.6mm, 2.0mm and 2.5mm.

1.60 Millimeter Gauge

1.6mm gauge edging is suited to most domestic edging applications, it has a rounded top lip width of 5.5mm which gives it a great deal of strength and yet it is still incredibly easy to shape. It is recommended to select a thicker gauge for any publicly installed applications.

Available in REDCOR® and Galvanised.


2.00 Millimeter Gauge

If you are after an edge with more strength, for extended straight lines or driveway edging that’s likely to be hit by cars from time to time, then the 2.0mm gauge will be a better choice. With its 7.0mm top lip it naturally offers more strength, but is still easy enough to be curved and shaped.

Available in REDCOR®, Galvanised and ZAM®.

2.50 Millimeter Gauge

For the ultimate strength we offer a 2.5mm gauge steel with a 8.0mm top lip. It’s suited to heavily trafficked public spaces and applications where longevity is crucial. It can also be used around the house and will be strong enough to deal with the day to day knocks for many, many years. Nothing compares to the 2.5mm gauge when you’re after a fast installation of straight lines.

Available in Galvanised and ZAM® (REDCOR® is approximately 20% stronger than the galvanised so 2.5mm is not generally necessary but it is available for special applications).

(Stainless steel is available by special request only.)

We decided to assault our edging with a truck to prove a point. (it is empty)

For each application, a varying level of strength will be required. I wanted to show just how strong our 2.5mm commercial gauge of galvanised edging is, by driving a truck on top of it! For public spaces a minimum of 2.0mm gauge is definitely recommended. It is marginally more pricey but it will stay in shape for many years to come, as well as standing up to the test of time better than a thinner steel would.

Upgrading your project to a thicker gauge of edging will ensure there will be less maintenance for years to come.
