What gives us the edge?

CORE EDGE is produced directly by the team at CORE LP and is designed with more than 40 years of industry experience in mind. We know how important it is for landscaping products to work effectively and stand the test of time. For that reason we are dedicated to using premium materials for optimum strength and durability.

AkzoNobel Powder Coating.

The raw steel has a 20-micron galvanised zinc coating applied to eliminate rust.

The product is then finished with a 110-micron polyester UV stable powder coating, designed for the UK’s harsh outdoor climate.

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 scratch resistant flexible finish that is tougher than conventional paint.

Unique Dual Locking Tabs.

DUAL-LOCK MECHANISM™ | The dual lock mechanism on CORE EDGE provides a rigid connection between sections which results in a strong and seamless appearance, as well as the flexibility to choose between straight borders and curved edges.

A Full 5 Linear Metres.

Each pack of CORE EDGE contains five 1075mm strips of edging. This provides a full five metres of coverage once connected. That’s 6% more than our closest competitor.

‘Diamond Design’ Ground Spikes.

CORE EDGE features a unique fold along the centre of each ground spike, forming a ‘diamond’ structure.

This shape provides maximum strength and durability, even in tough terrain, preventing the ground spikes from curling under pressure.

Need Support? Try Our Extension Pins.

Our easy-to-install extension pins helps you to reinforce the ground spike by an additional 300mm.

The best part? You can easily add them afterwards, once the edging is in place. No need to go through the hassle of lifting the edgings completely.

Rounded Corners.

Easily achieve a soft right angle without any specialist tools.

Perfect Corners.

Create perfect 90° right angles by slightly scoring the edging. Be sure to spray the exposed steel with a metal primer.

Frequently Asked Questions

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.
