Metal edging systems offer many benefits above traditional materials used for edging gravel areas, such as concrete or timber, or no edging at all.


One of the chief advantages of metal edging is its flexibility. While it is robust enough to withstand lateral pressure from backfilled hard and soft landscaping, it is also flexible enough to be formed to the curves and shapes that give character to driveways and paths. The same cannot be said about concrete pin kerbing or timber edging.

Metal edging also features hidden connectors that ensure joins between the lengths of edging are smooth and seamless, without ugly overlaps.

Another benefit of metal edging is that it doesn’t require a concrete base or haunching. Cement and concrete exude acids that are hostile to plants and are a common cause of grass dieback when placed alongside grassed areas.

Gravel Areas design


Metal edging, made from steel or aluminium, is extremely durable. It is less prone to damage caused by the impact of a vehicle tyre or gardening machinery and unlike concrete, will not crack or crumble when exposed to frost. Neither will it warp, splinter or rot, like timber edging.

Aluminium is, of course, the ultimate in corrosion-proof edging but galvanised and weathering steel also have excellent corrosion resistance. Powder coating steel can also improve its protection while adding a colour dimension to blend or contrast with other elements in the landscape design.

Gravel Areas durability


Compared with concrete pin kerbing, metal edging is fast and easy to install. For a start, it is relatively lightweight and can easily be carried and laid single-handedly.

It doesn’t require a solid level base or haunching to fix it into position. Metal spikes driven into the ground hold it securely and work on the sub-base, gravel and backfilling of soft landscaping can continue as soon as the edging is in place.

These savings in manpower, materials and time, added to the extended low-maintenance lifetime of metal edging, more than compensate for the additional cost of this product.
