CORE EDGE - Flexible steel edgings & pre-rolled garden rings

A complete range of flexible steel edgings and pre-rolled tree rings designed to create the perfect edge restraint for a variety of landscaping applications. The ground spike incorporates a unique fold along its centre to provide maximum strength, reinforcing the spike, making it ideal for use in tougher ground conditions. If soft ground is encountered, a rebar extension simply fixes through the ground spike to provide additional stability. The entire range is quick and easy to install with no specialist tools required and is available in a range of finishes.









BRIGHT ZINC GALVANISED | Our unpainted galvanised finish is the most cost effective edging option!

The raw steel has a 20 micron galvanised zinc coating to increase the edgings life-span.

The galvanised coating will prevent the steel from rusting when exposed to the elements.


POWDER COATED | Our galvanised steel edgings are finished with a 110 micron polyester powder coating that is designed for external use.

The coating is applied electrostatically and is then cured under extreme heat to allow it to flow and form a “skin”. This skin creates a hard wearing flexible finish that is tougher than conventional paint.


CORE-TEN | Our high grade weathering steel has a unique look and naturally oxidizing finish. Weathering steels are a group of steel alloys which were developed to remove the need for painting which form a stable rust-like appearance when exposed to the elements.

6% MORE PER PACK | Our packs of edgings contain 5 lengths per pack, each length is 1075mm which is 6% longer than our closest competitor, Everedge.

The connecting overlap is 75mm per edge which means when a pack of 5 is connected together you lose 375mm of length. When a pack of CORE EDGE is connected  you will have 5 linear metres on the ground.

Double Lock Mechanism

DUAL LOCK MECHANISM | provides a rigid connection between adjoining edges, helping to provide an almost seamless connection with double locking tabs.

Once connected… if more hands are available, pre-joined edges can be installed as one continuous length. Making it far easier to create larger curves or complex shapes.

Pin Extensions

EXTENSION PINS |  The easy-to-install expanding clip and galvanised rebar means you can reinforce the ground spike by an additional 300mm.

One of the main benefits of the system is that it can be installed after the edging has started to be installed. This means you will not need to re-lift any edgings to add additional support.

Using a hose or rope, make a guide for your edging to follow. If the ground is relatively soft you’re good to go. If not, you may need to loosen the ground with a flat spade or pick axe to ensure the edging can be installed without difficulty.


Starting at one end, tap the edging down using a wooden block and mallet. Ensure the edging remains vertical as it is driven into the ground, this prevents twisting when it comes to installing your next edging.


Before driving the whole edging into the ground connect the next edging. Try to maintain a continuous line along the top of the edgings when tapping them into the ground to prevent the connections from coming apart.


Connect the edgings by sliding the large tab on one edging down through the slit on the adjacent edging. Using a pair of thin nosed pliers, pull both thin tabs through the slit provided and rotate them back on themselves to secure the two edgings.


If using the edging on a lawn area the top of the edging should be flush with the soil to prevent the lawn mower blade making contact with the top of the edging.


If you have an edging that is too long, you can either overlap the last two edgings or cut one of the edgings to size using a hacksaw. Be sure to use a metal fie to smooth over the cut end and we recommend applying a metal primer paint to prevent rusting.

What’s the best way to form a curve with CORE EDGE?

To create a tight radius its best to form the curve by bending each individual edge around a suitable cylindrical object such as a bucket full of soil or a rounded post. For a gentler curve you can either bend each edging slightly by hand and connect together as you go, or if you have more hands on site connect the required amount of edgings, making sure you securely fasten the dual locking tabs, then starting from one end form the curve by tapping the edgings into the ground as you go whilst the desired curve is formed and held in place by your workmates.

What’s the best way to measure a curved or complex shape?

Simply lay out a string line or rope to the desired shape, then lift it and measure its length.
It’s always easier to mark the ground with a spray can or wooden stakes before lifting the rope to make sure your edging goes exactly as you first intended.

What’s the best way to install CORE Edge in particularly soft ground?

The pre-formed spikes will tap easily into soft ground. Its best to place a piece of brick or a flat stone under the edging at intervals to avoid the edge cutting down into the ground if there is a possibility of weight being applied directly onto the edging. Alternatively back the edge up with a concrete haunching that sits slightly below the edging. If the edge is going to sit above ground for a raised border, it’s often useful to use our galvanised stabilising pins.

What’s the best way to install CORE EDGE in hard ground?

The spikes on CORE EDGE are quite tough and will tap into most firm ground with the aid of a wooden mallet or block of wood, but if the ground is really hard its best to loosen it first with a fork or pick axe. Firm the ground by treading the soil back against the edging on completion. If the edge is going to sit above ground for a raised border, it may be necessary to use our galvanised stabilising pins.

What’s the best way to cut CORE EDGE?

CORE EDGE can be easily cut using a hacksaw or grinder, please take care with sharp edges and use metal primer on exposed steel.

How long will CORE Edge last?

CORE EDGE is made from 1.6mm mild steel with a 20 micron galvanised coating and a 90-110micron thick polyester powder coat. Under normal conditions it has a life expectancy of over 15 years.

Can I use heavy compaction machinery close to CORE EDGE?

Yes. But as with all edge restraints be sure to support the exposed edgings with temporary pegs or galvanised stabilising pins to avoid “bowing” caused by over compaction.

Why CORE EDGE Works Perfectly with Artificial Grass

Combining the Two

CORE EDGE Flexible Lawn Edging is a problem solving product that enables the user to be creative with the way they use it. With the user being able to achieve smooth curves, bold lines, right angles and intricate bends with the flexible steel, it allows for it to be the perfect edge restraint for artificial grass installs.

Working in Tandem

The picture showcased here is a perfect demonstration of how well CORE EDGE facilitates an artificial grass install. The installer here is using CORE EDGE in the correct way by tapping the grass in neat and tight, relying on the lawn edging to provide the perfect edge restraint.

Seamless Combination

The examples seen here demonstrate how well you can team artificial turf with carefully planted flower beds! A great example of how both natural gardening and brilliantly well made products can team together to make a garden really work. The lawn edging creates the ideal framework to install artificial grass within!
