22" Height Flexible Steel Edging - Weathering Steel

22" Height Flexible Weathering Steel Edging Panels

When your design calls for sweeping curves, organic shapes, or flowing lines, Flexible is the answer. Straightcurve's 22" flexible CorTen steel edging bends to follow any radius — curved raised beds, sweeping terraces, kidney-shaped kitchen gardens, and retaining walls that follow the natural contour of the land. Same 2mm CorTen construction and 8mm top edge as the Rigid range, but with the freedom to curve.

💡 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 22" 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 — Mid-height option for accessible curved beds and tiered designs
• 22" Height — You are here. 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
• Kidney-shaped and freeform planter boxes
• Sweeping terraces and curved retaining walls
• Kitchen gardens with flowing layouts
• Rooftop and hard surface (decking) installations
• Raised border edging with curves
• 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.
