9.5" Height Rigid Weathering Steel Edging

9.5" Height Rigid Weathering Steel Edging Panels

Clean, low-profile, and built to hold a perfectly straight line. Straightcurve's 9.5" rigid CorTen steel edging is the go-to choice for landscape borders, shallow raised beds, patio installations, and rooftop gardens where a sleek edge and precise dimensions are the priority. Unlike Zero Flex, Rigid panels can be cut and rejoined with a sleeve — giving you complete control over your layout.

Rigid edging comes in three heights to suit any project:

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

💡 Pro Tip: Mix Heights on Sloped Sites — All three Rigid 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. A smart technique for terraced gardens, sloped retaining walls, and hillside installations.

🛠️ Use our free Planter Box Configurator to design your layout and get an exact parts list.

Note: The configurator is designed for fully closed planter boxes (square, rectangular, or L-shaped). Rigid edging is also ideal for open-ended applications — single-sided retaining walls, 2-sided corners, 3-sided U-shapes, and straight barrier runs. For those layouts, use the configurator as a starting point and adjust quantities as needed, or email us and we'll help you work out exactly what you need.

Joining sleeves are only needed if you are cutting the edging (which removes the built-in connectors) and need to rejoin the panels. Add the sleeve variant above if your project requires non-standard panel lengths.
