15.75" Height Flexible Steel Edging - Weathering Steel

15.75" Height Flexible Weathering Steel Edging Panels

The versatile mid-height choice for curved landscape work. Straightcurve's 15.75" flexible CorTen steel edging bends to follow any radius — perfect for accessible curved raised beds, sweeping tiered designs, and retaining walls that follow the natural contour of the land. At a height that's ideal when a full 22" would be too tall, it delivers the same 2mm CorTen construction and 8mm top edge as the rest of the Flexible range.

💡 Flexible and Rigid edging connect together using the same connector system. Use Flexible panels on the curved sections of your design and Rigid panels on the straight runs — all at the same height, all in the same project. This is the go-to approach for kidney-shaped beds, curved retaining walls with straight ends, and any design that combines flowing and geometric elements.

See the matching 15.75" Rigid Edging for the straight-line version.

Flexible edging comes in three heights to suit any project:

• 9.5" Height — Low-profile curved edging for borders, shallow beds, and patio installations
• 15.75" Height — You are here. Mid-height option for accessible curved beds and tiered designs
• 22" Height — The most popular height for deep curved raised beds and statement planters

💡 Pro Tip: Mix Heights on Sloped Sites — All three Flexible heights (9.5", 15.75", and 22") can be connected together and leveled at the top. As the ground rises, step down to a shorter panel — so you're never burying more steel than necessary. Works the same way as the Rigid range, and you can mix Flexible and Rigid heights in the same sloped run.

• Bends to any radius — ideal for organic, flowing, and curved designs
• Connects directly with Rigid edging — mix curves and straight lines in one project
• All three Flexible heights connect together — ideal for sloped sites
• 2mm thick CorTen (weathering steel) — built to outlast the job site
• 8mm top edge — no sharp edges, clean professional finish
• Panels sold in pairs — mix and match sizes for any configuration
• Arrives in pre-rust state — natural patina develops after installation
• Preformed corners available — 4" each side of the 90° bend

• Curved and organic raised garden beds
• Accessible and tiered curved garden designs
• Sweeping terraces and curved retaining walls
• Kitchen gardens with flowing layouts
• Rooftop and hard surface (decking) installations
• Mixed designs combining curves and straight lines with Rigid panels
• Sloped sites using mixed heights leveled at the top

• Large Panels — 2 x 71"
• Medium Panels — 2 x 31.5"
• Filler Packs — 2 x 15.75" and 2 x 8"
• All panels: 2mm thick, 8mm top edge
• Preformed corners: 4" each side of the 90° bend

• Long twisted nails and connectors included with panels
• Tek screws and driver bit included when purchasing anchor posts
• Not included: anchor posts, universal bracing, preformed corners, and joining sleeves (available as add-ons)

Bracing is required in most installations. Choose between Universal Bracing or Anchor Posts (or a combination). Universal Bracing is recommended for the easiest installation.

• 2 per section for 71" panels
• 1 per section for 31.5" panels

Anchor posts are installed by tek-screwing to the ribs (brackets) on the back of the edging — self-tapping screws, no pre-drilling needed.

Joining sleeves are only needed if you are cutting the edging (which removes the built-in connectors) and need to rejoin the panels.
