Our 4" x 10 FT Medium Duty TerraEdge landscape edging 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.
