3" Height Flex Garden Edging - Weathering Steel

3" Height Flex Weathering Steel Garden Edging

The most discreet curved edging in the Straightcurve range. The 3" Flex bends to follow any organic line — sweeping lawn borders, curved path edges, flowing garden beds, and decorative stone dividers where a clean, low profile is the goal. Same 2mm CorTen construction as the rest of the Flex family, with a 6mm folded top edge that sits neatly at grade.

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

See the matching 3" Zero Flex Rigid Edging for the straight-line version.

Flex garden edging comes in three low-profile heights:

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

• Organic and flowing garden borders
• Curved lawn edges and path borders
• Raised curved feature gardens
• Kitchen garden beds with flowing layouts
• Curved, sweeping terraces
• Decorative stone, gravel, and mulch dividers
• Hard surface mounting — rooftops and decking
• Mixed designs combining curves and straight lines with Zero Flex Rigid panels

• 3" high x 86.75" long sections (7.22 feet per section)
• 2mm thick CorTen (weathering steel) — built to outlast the job site
• 6mm top edge — folded lip, no sharp edges
• Pre-scored corners — 10" each side of the score line, or make your own
• Joining plates and spiked nails included
• Arrives in pre-rust state (black/gray) — natural patina develops after installation

Pre-scored corners are 10" each side of the score line. You can also create your own — see the installation video for instructions.
