What is metal edging and why use it?
Metal edging is a durable, flexible material used to define clean, crisp lines between different areas of a landscape, such as lawns, flower beds, paths, driveways or paving.
Made from materials like steel or aluminium, it acts as a barrier that keeps soul, gravel, mulch or grass in place while preventing unwanted movement or spreading.
So, why choose metal over other edging materials like plastic, wood or concrete?
Key benefits of metal edging include:
- Strength and durability: Metal edging resists cracking, rotting and UV damage. This makes it ideal for long-term use.
- Sleek aesthetics: Its minimal profile creates a sharp, modern look that works in both traditional and contemporary designs.
- Flexibility: Many metal edging systems can be shaped on-site to follow curves and angles in your design.
- Low maintenance: Once installed correctly, metal edging requires little upkeep over the years.
Whether you are designing a private garden or a high-traffic public space, metal lawn edging provides a strong, long-lasting solution for defining and protecting your landscape design.

Types of metal landscape edging: Which one is right for your project?
The best metal edging for your project depends on its purpose and the desired aesthetic. Different materials offer distinct advantages when it comes to strength, flexibility and appearance.
Steel edging
Steel is the go-to choice for strength and durability. It holds its shape exceptionally well and can withstand pressure from vehicles or heavy foot traffic, making it ideal for:
- Driveways
- Public spaces
- High-traffic walkways
- Commercial landscaping projects
Steel landscape edging offers a sleek, modern look and is available in finishes like galvanised or weathered corten for a natural rusted effect.
Aluminium edging
Aluminium is a lightweight yet tough option that resists corrosion, even in damp or coastal environments. It is easy to handle and install, making it a popular choice for:
- Garden beds
- Lawn borders
- Residential paths
- Decorative landscaping features
Aluminium is particularly well-suited to curved designs due to its flexibility and ease of shaping on site.
How durable is metal garden edging? Lifespan and longevity explained
When properly installed and maintained, metal edging can last decades, making it a cost-effective solution in the long run.
Both steel and aluminium metal edging offer long lifespans with minimal maintenance, lasting at least 30 years.

Does metal edging rust? What you need to know
Rust is a common concern with metal products, but whether metal edging rusts depends on the material and finish.
- Steel edging can rust over time, but treatments like galvanising help protect it from corrosion. Corten steel is designed to develop a stable rust-like patina, which protects the metal underneath and gives it a distinctive, weathered look.
- Aluminium edging does not rust. It forms a natural oxide layer that protects in from corrosion. This makes it ideal for wet or coastal environments.
How to install metal edging for a professional finish
Installing metal edging correctly is key to achieving a clean, long-lasting result. Whether you are shaping garden borders or defining paths, following these basic steps will help you get a professional finish:
- Plan and mark your layout
- Excavate a shallow trench
- Place the metal edging
- Secure with stakes or pins
- Connect the sections
- Backfill and tamp down
Taking your time during installation will pay off in a sharp, durable finish that enhances the overall look and function of your landscape.

Tools you need for a smooth metal edging installation
Having the right tools on hand makes installing metal edging faster, easier and more precise. Here is what you will typically need:
- Hammer: For driving stakes into the ground
- Hacksaw/angle grinder: To cut edging sections to the right length
- Level: To check that the edging sits evenly along its length
- Tape measure: For accurate measurements
- Spray paint: To mark out your edging layout clearly
- String line: To mark out straight, precise guide lines
- Shovel/spade: For digging a shallow, narrow trench along your edging line
With these tools ready, you will be set for a smooth and professional installation process.
Keeping it in shape: Maintenance tips for metal edging
Proper maintenance helps your metal edging look great and last even longer. Here are some simple tips to keep it in top condition:
- Regularly check for movement or shifting: Over time, soil settling or heavy use can cause edging to shift. Re-secure any loose sections with stakes or pins.
- Remove debris and vegetation: Clear away leaves, grass clippings and weeds that can trap moisture against the metal and promote corrosion.
- Keep edges clean: Washing off dirt and mud prevents buildup that can hide problems.
- Avoid heavy impacts: Try to prevent damage from lawnmowers or heavy equipment by keeping a buffer zone around the edging.
Is metal edging safe for gardens, public spaces and play areas?
When properly selected and installed, metal edging is a safe choice for gardens, public spaces and even play areas. Here is what makes it safe and how to ensure it stays that way:
- Smooth, rounded edges: Many modern metal edging products are designed with smooth or rolled edges to minimise sharpness and reduce the risk of cuts or injuries.
- Flush installation: Installing edging so that the top sits just above or slightly below ground level prevents tripping hazards while still defining spaces clearly.
- Durability: Metal edging won’t splinter, crack or break like wood or plastic. This makes it safer for areas with children and high foot traffic.
- Non-toxic materials: Most metal edging is made from environmentally safe materials that won’t leach harmful substances into soil or plants.
