Advantages of Corten Steel Edging
Durability
Corten steel has exceptional resistance to atmospheric corrosion thanks to its protective rust patina, forming a smart barrier against further decay. This makes it last for decades without cracking, rotting, or bending out of shape.
01
Weather Resistance
Corten steel withstands exposure to rain, sun, wind, frost, and snow, without damage or wear. The material will never warp, splinter, or degrade like other edging materials.
02
Aesthetic Appeal
The rust patina on corten steel creates a unique aesthetic that brings artistic style to garden beds and borders. The textured rust-orange hue contrasts beautifully with greenery and stone, and this eye-catching appearance remains intact for years.
03
Sustainability
As a recyclable material, corten steel reduces waste compared to less eco-friendly edging options. Plus, the production process uses fewer resources than mining virgin materials, and our edging range is made of 60% recycled material.
04
Low-Maintenance
Once installed, corten steel requires minimal maintenance thanks to its protective rust layer. This means there is no need for time-consuming repairs, replacements, or repainting during its lifespan.
05
Flame Cut Edges
A high-temperature flame melts the metal and blows away the slag to create an edge. Suitable for cutting beams in weathering steel bridges and roughing the edges of landscape sculptures.
Plasma Cut Edges
A high-temperature plasma arc melts the metal, and a high-speed airflow blows away the slag. Suitable for cutting special shapes in building curtain wall units and weathering steel decorative panels.
Laser Cut Edges
A high-energy-density laser beam melts the metal, and an assist gas blows away the slag. Suitable for fine edge processing of weathering steel signage and art installations.
Applications of Corten Steel Edging
Lawn edging
Create clear, defined lines around turf areas.
Borders and beds
Ideal for shaping garden beds, vegetable patches, and herb gardens.
Area separation
Use as a border edging to divide sections within a garden.
Driveways and gravel paths
Maintain shape and prevent movement of materials.
Courtyards and rockeries
Add structure and contrast.
Raised beds
A perfect edging system for keeping soil and mulch in place.
Installation of Corten Steel Landscape Edging
Installing Your Corten Steel Edging
Installing your Corten steel edging is straightforward and can be adapted to suit different project types, whether you’re working on a garden path, curved lawn border, or raised bed. Installation methods vary depending on your project and tools available:
Welding or bolting: Join strips together by welding or drilling holes and connecting with metal plates that sit below the finished surface.
Pegs: Secure edging in place using Corten pegs or Corten fold-over pegs. For a secure fit, especially in softer ground conditions, we recommend 4 pegs for the first strip of edging, then 3 pegs per additional length of edging laid.
Our fold-over pegs are easy to install – Just double your edging height to pick the right size peg. You can also use our Corten edging corner pieces to achieve clean 90-degree angles with ease. We recommend using 2 corner pieces per corner.
If you need to shape your edging around curved beds or borders, the flexibility of our Corten steel edging makes it easy to bend the strips by hand or with the help of basic tools. This allows for clean, sweeping lines that flow naturally within your garden design.

Aesthetic Appeal
Colour Changes Over Time
As Corten steel develops its patina, the colour can change from bright orange to deep brown or even shades of grey, depending on the environmental conditions. This process can create a rich visual texture that enhances your garden's overall appeal.
Complementing Different Styles
Whether you're going for a modern minimalist look or a more rustic farmhouse vibe, Corten edging can complement various landscaping styles. I've installed it in contemporary gardens, where the clean lines of the edging frame beautifully manicured lawns, and in wildflower gardens, where it provides a structured contrast to the chaos of nature. The versatility of Corten steel is one of the reasons I recommend it to clients looking to achieve a specific aesthetic in their outdoor spaces.
Creating Dynamic Landscapes
Corten edging can also be used creatively to create curves and geometric shapes in your garden layout. Manipulating the steel into various forms allows you to create distinct planting areas, pathways, or borders that can help define your garden's character. In my experience, gardens with Corten edging often draw more attention, making them conversation starters among guests and neighbours.
Expected Lifetime of Weathering Steel Edges
In terms of lifespan, it’s impossible to offer a one-size-fits-all promise with the variety of soil and atmospherics that can impact this natural process of corrosion. We know weathering steel edging can last decades and hold its structural integrity even as it corrodes. This is a product deserving of its long-lasting credential, but not one to carry a fixed-guarantee due to all the factors in play.
It is more accurate to say that weathering steel is much more durable and typically lasts 4-6 times longer than mild steel. In terms of lifespan, 1.5mm panels of Corten or weathering steel is equivalent to a 6-9mm mild steel flat bar. In practical terms, this means Corten Steel Edging can last anywhere between 5 and 30 years.
The actual lifespan of your Corten Steel Edging depends on various factors such as your location, water conditions, and soil conditions.
If you use well water, which is often acidic or saline, the lifespan of the edge will be significantly shortened. If you use tap water, the edge will last longer unless the water has high chlorine levels. Additionally, the edge of the pool may not perform well unless it is sealed.
How to Extend the Life of Weathering Steel Edges
Let the Patina Develop Naturally
The rusted patina on Corten steel is essential for its durability. It typically takes 6 to 12 months for the patina to form fully. During this period, it's important not to interfere with the process. Some people try to speed up the rusting with chemicals, but I've found that it's better to let nature take its course. A rushed patina tends to flake off, which defeats the purpose of Corten's weathering process.
Regular Cleaning and Inspections
Although Corten doesn't require much maintenance, I recommend giving it a light scrub with a wire brush once a year to remove loose rust or dirt buildup. Brushing it will help the patina stay consistent if the steel looks uneven or has flaky rust.
Smart Installation Practices
When I install Corten edging, I always raise it slightly above the soil level. This keeps water from pooling around the base, which can cause faster corrosion. It's also a good idea to anchor the edging securely so it doesn't shift over time, especially if you're working on a sloped area.
Protective Coatings for Wet Climates
Applying a clear sealant can add an extra layer of protection to gardens in high-moisture environments. While it's not strictly necessary, it can give you peace of mind if you live in a rainy area. I've used sealants on some projects, and they help maintain the look of the patina while slowing down further rusting.
Cleaning and preserving your Corten steel edging
Regular cleaning can help remove any accumulated dirt or debris from the surface of your Corten steel edging. You can achieve this by gently washing the edging with mild soap and water, then drying it and applying a protective sealant. This sealant will help maintain the natural patina while protecting the steel from excessive weathering.
