Our 4" x 10 FT Heavy Duty TerraEdge is galvanized steel edging used to permanently delineate landscape beds, walkways, and gardens from lawn areas. The edging is manufactured from mild steel and coated with a corrosion-resistant plated finish, making it weather resistant and very low maintenance. Due to the nature of the steel, the edging can bend to form any curve and will accommodate a wide variety of designs.
