Rigid Weathering Steel Edging - 9.5", 15.75" & 22" Heights

When your project calls for clean straight lines, precise geometry, and edges that hold their shape for decades, Rigid is the answer. Straightcurve's tall Rigid edging range delivers contractor-grade rigidity in three heights — raised beds, retaining walls, terraces, and planter boxes where a straight, unwavering edge is the goal. Same 2mm CorTen (weathering steel) construction as the Flexible range, built to outlast the job site.

Three Heights to Suit Any Project

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

Mix Straight Lines and Curves in One Project

Rigid and Flexible edging connect together using the same connector system — use Rigid panels on the straight runs and Flexible panels on the curved sections, all at the same height. Mix heights across sloped sites and level at the top so you're never burying more steel than necessary.

Why CorTen Weathering Steel?

• 2mm thick — built to outlast the job site
• 8mm folded top edge — no sharp edges, clean professional finish
• Arrives in pre-rust state — natural CorTen patina develops after installation
• No painting, sealing, or maintenance required
