Optigreen Aluminum Edge is used to retain soil at roof edges, to separate soil from gravel borders, and to separate soil from paved areas. Hundreds of small holes are punched on the vertical leg to provide ample drainage while retaining soil. Two standard heights are available: 4” (100mm) and 6” (150mm). Both are made from a 60 mil (1.5mm) high-strength aluminum alloy, and both have a 6” (150mm) extra-wide base flange for stability. The flange can also be taped or welded to underlying membranes or fabrics through the large holes provided.
Aluminum Edge is supplied in 79” (2m) lengths. Multiple edges are joined by connectors that slide into folds in their edges, and welded corners with both inside and outside flanges join with the same connectors to provide strong, attractive corners.
