4" Height Rigid Garden Edging - Weathering

4" Height Rigid Weathering Steel Garden Edging

Crisp, straight lines that hold their shape for decades. Straightcurve's 4" Rigid CorTen steel edging is the choice for formal garden designs, feature bed borders, paving lock-in, and anywhere a perfectly straight edge is the goal. At 4" tall it sits with just enough presence to define a space without dominating it — same 2mm CorTen construction and 8mm folded top edge as the rest of the Rigid family.

💡 Rigid and Flex edging connect together using the same connector system. Use Rigid panels on the straight runs of your design and Flex panels on the curved sections — all at the same height, all in the same project. Perfect for designs that combine crisp geometric lines with flowing organic shapes.

See the matching 4" Flex Edging for the curved version.

Rigid garden edging comes in three low-profile heights:

• 3" Height — The most discreet option for lawn edges and path borders
• 4" Height — You are here. A little more presence for feature beds and paving lock-in
• 6" Height — The tallest Rigid edging height for invasive grass barriers and deeper borders

• Straight garden paths and geometric designs
• Feature bed borders and low raised borders
• Formal courtyard gardens
• Angular tree surrounds
• Lock in paving or compacted/loose fill paths
• Lawn barrier for non-invasive grasses
• Divider between gravels, woodchips, and mulch
• Mixed designs combining straight lines and curves with Flex panels

• Long Panels — 4 x 71"
• Short Panels — 2 x 31.5"
• Filler Pack — 1 x 15.75" and 2 x 8"
• Corners — 2 per box, 4" each side of the bend — bend to whatever angle you need
• All panels: 2mm thick, 8mm top edge

• Connectors and spiked nails included
• Arrives in pre-rust state (black/gray) — natural patina develops after installation
