Why use metal border edging?

A crisp metal edged border not only looks fantastic but has numerous practical advantages too.

Over time beds and borders without a metal edge will creep and loose their shape as a result of foot or mower traffic, grass creeping into the border and erosion.

Install a steel border edge and it’s there for life, when you trim your lawn the grass can be cut right up against the steel resulting in an incredibly crisp line every time. Not only is it very satisfying but ensures your border edges retain their shape for many years to come. Where your flowerbed meets gravel a metal bed edge with help prevent the migration of soil or mulch into your driveway and gravel into your border.

A metal border and bed edge will prevent grass creeping into your borders and your plants creeping onto the lawn to ensure you have a permeant divide between the two.

From a maintenance perspective a steel bed and border edge makes it so easy, simply run your strimmer or rest edging sheers against the steel edge to cut the grass right against the steel for a perfect, clean lawn edge

Why choose our metal border edging?

Where to start !!

Firstly our staking system, the long stakes (up to 50cm for our tallest edge) ensure your metal edge will remain firmly in place. Knocking the loose stakes through the sleeves allow you to get the steel edge in just the right position before inserting and hammering the stakes home. This is much easier than trying to install edging with the stakes already fixed.

Secondly our joining system, borders tend to have tighter and more curves compared to driveway and path edges. Curves are unaffected by our robust joins so your border edges will flow uninterrupted.

Thirdly our range. For particularly curved borders we recommend our 3mm thick edging for its flexibility, this will naturally form curves with a radius down to 1 meter and anything less the edge can be bent by hand (requires some elbow grease !). For straight lines our 6mm edge is ideal. The thicker, more rigid steel is better at forming and retaining straight edges to beds and borders. The thicker steel is also ideal for traffic areas where your steel bed edging is likely to be driven over.

With regards to height options, the most popular height for metal edging borders is 100mm, however this does depend on the height of the edge your looking to retain. Our 75mm high edge may be high enough where there is little height difference between the border and the ground level behind it. For borders with a particular deep edge we offer a 150mm, 200mm and even a 300mm high edge however it’s unlikely that the taller edge will be required except in more extreme circumstances. For a fuller description of our range see the section on our main edging page or watch the Steelscapes edge explained video.

As a rule of thumb the bottom of the edge should be buried in the ground around a third of its height for stability and to prevent plants creeping underneath. When edging borders adjoining driveways we recommend our 6mm thick edging and burying around half in the ground. Installed correctly ours is one of the few edging systems able to tolerate being driven over.

Tips on how to install your steel bed edge

A steel border and bed edge can be installed into an existing border or during the construction of a new bed or border, creating a new border usually means you have a clear run and simply install the edge where and at the height you require. Installation can be done more rapidly by connecting 2 to 4 lengths of edge together before installing, ensure this is done right next to where it is required and take care when placing into position.

To edge an existing bed with steel is common practice and is a little more involved, we have detailed the steps below:-

  • Begin by cutting back overhanging plants to expose the edge and give you good access to it. Bear in mind that the steel will form very nice fluid curves if just pushed in the right direction, this will iron out any unwanted kinks or notches in the existing edge, with this in mind any areas which project into a smooth edge line are best removed if possible.
  • For straight edges set up a string line on the border side of the edge which is seen but set around 1/2 centimetre away to allow space to work. You may be surprised just how un straight
    your border edge is with the line up! 
  • For both curved and straight edges we recommend cutting a fresh edge working to a string line on straight runs or creating more fluid curves. Cut at a slight angle into the raised side using a spade / edging iron. For example when edging a lawn edge of a border, cut into the raised lawn towards the base, this will ensure there are no obstructions to prevent the edge getting close up against the lawn. 
  • As your steel edge should be sunk into the ground by around a third of its height for additional stability. With this in mind dig a narrow channel along the base of your newly cut edge.
    With your nice edge cut ready to receive your metal border edging it’s ready to install. Using the joining plates to attach 2 to 4 lengths together before installing will speed the process up. We recommend setting the fixings side into the lawn edge so you are left with a clear, uninterrupted face on the seen side, this may require a bar or spade to push the edge into the face of the soil.

Lay the edge in position and when your happy with it insert the stakes and hammer them home.

It’s worth leaving the last couple of sleeves without stakes so you can pull the edge back slightly to give you space to connect the rest of the run.

Take care to get the edge at the correct height although it can usually be hammered down or levered up after installation, however after a few weeks when the ground has settled around the edge this will become difficult.

If edging a lawn on most occasions the edge will show up imperfections in the lawn either areas which are too low or gaps between the edge and lawn. To remedy this simply back fill with some nice top soil and grass seed.

Once installed your edge should provide a lifetime of service, quietly helping your garden look fantastic!
