4" Height Flex Garden Edging - Weathering

4" Height Flex Weathering Steel Garden Edging

A step up in presence without losing that clean, low profile. The 4" Flex bends to follow any organic line — curved feature bed borders, flowing path edges, paving lock-in with curves, and formal courtyard designs where straight lines just won't do. Same 2mm CorTen construction as the rest of the Flex family, with an 8mm folded top edge that's tough enough for heavy-use areas.

💡 Flex and 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 4" Rigid Edging for the straight-line version.

Flex garden edging comes in three low-profile heights:

• 3" Height — The most discreet option for curved lawn edges and path borders
• 4" Height — You are here. A little more presence for curved feature beds and paving borders
