Steel garden edging is one of the easiest ways to give your garden beds and zones a clean edge and keep everything exactly where it belongs. No more borders slowly wandering off or grass launching sneak attacks where it shouldn’t be. Steel handles all of that because it stays straight, resists warping and holds its shape for decades. In other words, it behaves itself. Let’s walk through what you can expect and how to install steel edging step by step, without the stress.
Unlike plastic edging, which has a habit of warping, shifting or giving up altogether, steel is built for the long haul. It creates a strong, reliable boundary that keeps soil neatly contained and garden lines looking sharp. You’ll often see steel edging used around lawn edges, raised or in-ground garden beds, gravel paths and walkways, plus decorative features and tree surrounds.
The real bonus is the look. Steel edging suits just about every garden style going around. Whether you love crisp, modern lines or something a little more relaxed and natural, it fits right in without stealing the spotlight.
Before you dive in, it pays to have everything ready to go:
Steel edging (with included stakes or pins)
Shovel or trenching tool
String line and spray paint (for marking your layout)
Rubber mallet or hammer
Spirit level
Hacksaw or chop saw (for cutting, if needed)
Safety gear: gloves and safety glasses
Optional: decorative pebbles, pre-fabricated corner pieces, connectors
Don’t skip the safety basics. Gloves, glasses and good lifting technique go a long way. Safe Work Australia’s guide to manual tasks has plenty of handy advice for working safely in the garden.
Below is a straightforward method that works for most steel edging systems, including Straightcurve.
Start by measuring the total length of edging you’ll need. Use a string line or spray paint to mark exactly where the edging will run. Take extra care around curves and corners, as these areas may need a bit more thought or prefabricated corner pieces, like the weathered steel corner pieces we stock.
If you’re edging a garden bed, it’s worth allowing a small overlap for mowing strips or border planting. Your future self will thank you.
Using a shovel or trenching tool, dig a shallow trench along your marked line. Aim for a depth of around half the height of your steel edging strip. This gives the edging solid support while still leaving a visible, defined edge above ground.
If you hit compacted soil or stubborn roots, slow down and work in sections. There’s no prize for rushing and ending up crooked.
Place the steel edging into the trench and adjust the depth so the top edge sits flush with your lawn, path or garden surface. If you want a more pronounced look, let it sit slightly higher.
Run a spirit level along the edging to keep everything nice and even. For curved sections, gently bend the steel by hand before placing it into the trench. Steel is strong, not stubborn.
Once the edging is in position, secure it using the stakes, pins or screw-in connectors that come with your kit.
Insert the stakes through the fixing holes and tap them in with a rubber mallet or hammer. If your kit uses screw connectors, follow the instructions to tighten the joints and lock everything in place.
Corners and curves need a bit of extra love, so add more stakes in these areas to keep the edging firm over time. If you need to trim lengths, use a hacksaw or chop saw and always wear gloves and safety glasses when cutting steel.
With the edging secured, backfill the trench using soil, mulch or gravel to suit the surrounding area. Fill gradually and keep an eye on alignment as you go.
Lightly compact the fill using your boot or a tamper. This step is key to preventing movement down the track. Once compacted, the clean, crisp finish that steel garden edging is known for really starts to shine.
Take a final walk along the edging and check the alignment. Straight sections should look even and level, and height consistency matters most where the edging meets turf, paving or similar surfaces.
Around corners and curves, make sure everything feels secure. If something looks slightly off, a gentle tap with a mallet or a quick stake adjustment usually sorts it out.
Once your steel edging is in, a few finishing touches can really elevate the result. Decorative pebbles add a clean, eye-catching border along paths, while mulch helps retain moisture and keeps weeds in check around plants. If your garden beds are looking tired, topping them up with quality garden soil can give plants the boost they need and refresh the whole space.
We stock all of these finishing touches, so you can wrap up the project without running all over town.
A bit of planning makes a big difference. Always use the right cutting tools and wear safety gear when working with steel. Pre-fabricated corner pieces are a lifesaver for tight angles and help keep joins neat and consistent. Handle steel carefully, as cut edges can be sharp, and gloves aren’t optional.
Rocky or sloped ground can complicate things, so if conditions are tricky, getting professional help can save time, frustration and a few sore muscles.
Most steel edging projects are very DIY-friendly, but some situations are better left to the pros. If your design includes tight decorative curves, lots of joins or transitions between materials, or needs to match existing structures perfectly, professional installation can be worth it.
