Which depth, colour and finish is best for the project
When Choosing EverEdge consider that it is available in metre lengths in different depths and finishes. The Galvanised and Powder Coated finish is available in three different depths, 75mm (colours are black, brown, green and silver), 100mm (colours are black and brown) and 125mm (colours are black and brown). In the Cor-Ten (rust) finish EverEdge is available in the 100mm and 125mm depths.
The galvanised and powder coated colours in black and brown are designed to be unobtrusive and give the impression that the soil is holding a nice neat edge. The Cor-Ten Steel makes more of a feature of the garden edges.
Further considerations when Choosing EverEdge
Generally the 75mm depth is used to edge lawns whilst the 100mm and 125mm depths are used to edge garden and vegetable beds. However, with most Australian lawns being created with grasses that send our runners (couch, kikuyu, buffalo, etc) it is very important to create an underground barrier to control the spread of the lawn into paths or beds. When about 30mm of the actual edge as well as the spikes is hammered into the ground this creates an underground barrier that will stop at least 80% of the runners (nothing will stop the few determined ones that go metres deep and cross under roads but at least they can be easily spotted and weeded or sprayed out). The 100mm and 125mm depths should therefore be used where control of grass runners is required.
