Lawn Edge galvanized steel edging is all-in-one. Each 106mm long section locks permanently into the next. No stakes or separate parts to come loose. Powder coated in four colors to match your landscaping décor (brown, black, slate, and Cor-Ten). Each piece is approximately 1.6mm thick and can be bent to form corners, curves, or circles. Cor-Ten is a product that is designed to weather naturally. Initially it appears as though it is just plain galvanized steel but, over time, a thin layer of rust forms a protective layer over the edging strip and does not break down like normal steel.
