In hardscape and landscape design, clean, precise lines help create well-defined features that elevate the overall appeal of an outdoor space. One way to create that crisp, professional look is by using metal edging in the landscape. It’s ideal for defining garden beds, pathways, driveways, and more. Thanks to its aesthetic and functional advantages, metal is a preferred choice by contractors throughout Canada’s diverse provinces, climates, and landscapes.

Benefits of Metal Edging

One of the primary advantages of metal edging is its durability. It can withstand harsh weather conditions, heavy foot traffic, and garden maintenance activities without deteriorating, resulting in fewer replacements and lower long-term costs. Meanwhile, it maintains the intended design and shape of a landscape by preventing grass and other plants from encroaching into pathways or garden beds.

Another notable benefit of metal edging is its flexibility in design. Metal is available in various shapes and sizes, and it can be easily bent or shaped to fit the curves and contours of simple and intricate landscaping projects alike.

Metal edging also requires minimal maintenance compared to other materials. It doesn’t rot, warp, or crack over time, making it a reliable choice for long-term use. 

Types of Metal Edging

Various types of metal edging are available to suit different needs and preferences. The most common types of metal edging are:

Steel Edging
Steel is known for being exceptionally strong and durable. Typically coated with protective finishes such as galvanized or powder-coated to prevent rust and corrosion, steel edging offers a sleek, modern appearance and can withstand heavy use and harsh conditions. It works well for high-traffic areas in larger cities and suburbs, or in any project requiring a long-lasting solution.

Aluminum Edging
Aluminum is lightweight and relatively easy to handle and install, while still being plenty strong. It’s naturally resistant to rust and corrosion, providing longevity along with a contemporary aesthetic. Aluminum’s flexibility allows it to be shaped to fit custom design requirements for charming residential gardens such as those in Montreal.

Corten Steel Edging
Corten steel, also known as weathering steel, develops a rust-like appearance over time, forming a protective layer against further corrosion. This unique characteristic gives Corten steel a rustic, industrial look that blends well with the rugged natural landscapes of the Canadian Rockies and the scenic beauty of Ontario's cottage country. It requires minimal maintenance and is particularly suitable for creating bold, statement-making edges in landscape design. Some manufacturers may have their own proprietary weathering steel (e.g., Border Concepts’ BORCON steel).

Each type of metal edging above brings its own advantages, allowing contractors to choose the best option for their specific project needs and aesthetic goals.

How to Install Metal Edging

Installing metal edging is a straightforward process, but achieving the best results requires careful planning and precise execution.

Step 1: Plan the Layout
Start by confirming the layout of your edging. Use a garden hose or string to mark the desired path, ensuring it is straight or follows the intended curves and angles. Measure the length of the path to determine the amount of metal edging needed. Gather the necessary tools, including a shovel, mallet, edging stakes, and safety gear.

Step 2: Dig the Trench
Next, dig a trench along the marked path using a shovel. The trench should be deep enough to accommodate the height of the metal edging, with a little extra depth to ensure stability. Typically, a trench 4-6 inches deep and 2-3 inches wide is sufficient for most metal edging installations.

Step 3: Position the Edging
Place the metal edging into the trench, ensuring it is aligned with the desired layout. For curved designs, carefully bend the edging to match the contours of the path. Use a mallet to tap the edging into place, making sure it is firmly seated in the trench. Check for level and adjust as needed.

Step 4: Secure the Edging
Drive stakes into the ground at regular intervals, typically every 2-3 feet. Ensure the stakes are flush with the top of the edging to avoid trip hazards. This will keep the edging in place and provide additional stability.

Step 5: Backfill and Settle
For final stability, backfill the trench with soil, packing it tightly around the edging. Once the edging is installed and secured, clean up the area by removing any excess soil and debris. Water the area lightly to settle the soil and perform a final inspection to ensure the edging is securely in place and the lines are clean and even.
