The individual elements can be placed on top of each other and fixed together by bending the punched pin with the help of a screwdriver. Installation is quickly done by pricking the soil with a lawn edger. The lawn edges can also be bent over a stable edge at any point. 

Our tip: For an efficient root barrier, set the lawn edging at least 8 cm into the ground. Depending on the height of the lawn edging, more or less of the edge will then protrude from the soil around the top of your bed, please consider your preferred height before your purchase.

The Metal Lawn Edging 12.5 is a galvanized, bendable steel edging strip designed to create clean, durable borders between lawn, beds, paths, and hardscape, with each piece measuring about 46.5 inches (12.5 feet total coverage per multiple pieces) and featuring a patented quick‑lock connection system for fast, tool‑light installation. This 12.5 metal lawn edging is robust, weather‑resistant, and flexible enough to form straight lines or smooth curves, making it ideal for both professional landscapers and DIY homeowners who want long‑lasting, low‑maintenance lawn edges.

What is Metal Lawn Edging 12.5?

When you see “Metal Lawn Edging 12.5”, it refers to a specific galvanized steel edging product line (often sold under SKU 41850560) where each element is approximately 1180 mm long (46.46 inches), 130 mm high (5.12 inches), and 0.65 mm thick. The “12.5” designation is used by brands like Pave Tech / Probst as a product name and also corresponds to the overall edging system sold per piece and in sets for about 12.5 feet of linear edging coverage.

Key technical data (per piece):

• Material: Galvanized bendable metal sheet (steel), robust and weather‑resistant.

• Thickness: 0.65 mm (approx. 0.03 in).

• Dimensions (L × W × H): 1180 × 0.65 × 130 mm (46.46 × 0.03 × 5.12 in).

• Weight: 0.91 kg (2.01 lb) per piece.

Retailers in North America list Metal Lawn Edging 12.5 – SKU 41850560 in their Probst/Pave Tech categories, typically priced around $11.50–$12.60 per piece.

Galvanized, Bendable, and Weather-Resistant

The Metal Lawn Edging 12.5 is made from galvanised bendable metal sheet, which combines durability with flexibility:

• Galvanized steel provides a zinc coating that resists rust and corrosion, even in wet soil and harsh weather.

• The 0.65 mm thickness is robust enough to hold shape and act as a root barrier or material separator, yet thin enough to bend by hand over a stable edge.

• The upper edge is flanged, creating a smooth, rolled top that is safer to handle and gives a clean visual line at the lawn or bed edge.

This makes the product suitable for long‑term use around lawns, flower beds, gravel paths, and patio edges where you need a durable yet subtly visible border.

Patented Quick-Lock Connection System

One of the standout features of Metal Lawn Edging 12.5 is its patented connection system, which lets you easily join multiple edging elements without separate connectors or complicated hardware:

• The punched pin at the end of each element can be bent over with a screwdriver to lock two pieces together.

• This creates a secure, aligned joint so several 46.5‑inch pieces can form longer continuous borders (e.g., 12.5 feet or more depending on how many pieces you buy).

• The perforated edge also allows variable angle adjustment up to 90°, so you can form corners or gentle curves without cutting special pieces.

This quick‑locking design makes installation faster and easier than many traditional steel edging systems that rely on stakes and bolts.

Flexible Design for Straight Lines and Curves

The Metal Lawn Edging 12.5 system is designed to be flexible enough to handle a wide variety of layouts:

• The metal strip can be bent over a stable edge at any point to create inside or outside corners.

• The perforated lower edge and the 0.65 mm thickness allow gentle curves and radii, ideal for organic garden shapes, tree rings, or curved pathways.

• Unlike rigid concrete or plastic edging, this steel edging can follow both straight and curved lines, while still holding back soil, mulch, or gravel effectively.

Landscape‑edging experts note that thinner, more flexible gauges are particularly useful for curves and tree rings, while still offering enough strength for most residential applications.

Installation: Quick, Simple, and Tool-Light

Pave Tech’s installation guidance for Metal Lawn Edging 12.5 emphasizes a quick, straightforward process:

1. Mark and prep the line: Mark the desired lawn edge and, if needed, lightly prick the soil with a lawn edger to create a narrow slit.

2. Insert the edging: Push each 12.5 edging element into the ground along the prepared line. The flanged top should remain at the desired finished height.

3. Connect elements: Stack or overlap adjacent pieces and lock them by bending the punched pin with a screwdriver to form a continuous strip.

4. Adjust angle: Use the perforated edge to bend the strip up to 90° for corners or transitions.

The manufacturer’s tip for performance and root control:

• For an efficient root barrier, set the lawn edging at least 8 cm (3+ inches) into the ground.

• Depending on the total height (130 mm / 5.12 in), this leaves a portion visible above the soil line; plan your preferred visible height before purchasing.

Unlike some heavier edging systems, this product doesn’t require separate stakes for basic residential installations, making it attractive for quick DIY projects.

Root Barrier and Lawn Separation

A key functional benefit of Metal Lawn Edging 12.5 is its performance as a root barrier and material separator:

• When installed at least 8 cm deep, the edging helps keep lawn grass from invading beds and gravel areas, reducing the need for constant trimming.

• The 5.12‑inch total height allows enough depth to resist root creep while still creating a clean, visible boundary at the surface.

• Metal edging in this height range is also recommended when you need to hold back loose materials like bark mulch, decorative stone, or soil mounds.

Industry guides suggest that 8–12 inch tall metal edging is ideal when you need functional support, not just decorative separation. Metal Lawn Edging 12.5 fits that profile at the more compact end, which is perfect for lawns and low beds.

Typical Uses for Metal Lawn Edging 12.5

Because of its dimensions and features, Metal Lawn Edging 12.5 is suited for many landscape tasks:

• Lawn–bed separation: Create crisp lines between turf and flowerbeds, shrubs, or perennial borders.

• Path and patio edging: Hold gravel, decomposed granite, or pavers in place along paths and small patio areas.

• Tree rings and radii: Form circular or free‑form edging around trees and specimen plantings using the bendable perforated edge.

• Slope and soil retention: Provide light soil‑holding support on gentle slopes, preventing mulch or soil from washing onto turf.

• Modern minimalist borders: The slim galvanised steel strip provides a clean, unobtrusive edge that works well in contemporary garden designs.

For heavier structural uses (large retaining edges or tall raised beds), thicker and taller gauges may be preferred, but for standard lawn edging, Metal Lawn Edging 12.5 offers an excellent balance of strength, flexibility, and ease of use.
