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

The UK’s No.1 Flexible Steel Edging

CORE EDGE is an innovative, easy-to-install flexible steel garden edging system, suitable for edging lawns, borders, patios, pathways, and driveways.

Manufactured here in the UK from a high quality 1.6mm mild steel, available in three face heights and five finishes. Each pack of 5 x 1075mm strips joins together to give 5 meters of edging once installed.

AkzoNobel Powder Coating

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

The product is then finished with a 110-micron polyester powder coating, 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.

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.


Galvanised Steel Range


Unique Dual Locking Tabs

CORE 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.

Superior Strength

7 REINFORCED GROUND SPIKES | The ground spike incorporates a unique fold along its center to provide maximum strength, reinforcing the spike, making it ideal for use in tougher ground conditions.

More Edge For Your Wedge


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 meters on the ground.

Extension Pins


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.
