Build a commanding raised-bed rim, retain deep gravel, or edge a formal driveway line with this 4-pack 40 in. x 12 in. steel landscape edging, a heavy-duty set of four 40 in. x 12 in. x 0.06 in. galvanized steel strips that cover about 13 ft. of border per pack with an 8.06 in. (204.8 mm) above-grade height, the tallest profile in the steel edging lineup. The taller above-grade surface holds back tall mulch layers, river rock, and raised-bed soil where 5 in. profiles fall short, which matters for stacked landscape projects and commercial-style beds. A 3.94 in. (100 mm) extended spike drives deeper than the 3.15 in. spikes used on shorter edging, anchoring the taller profile firmly in soft soil, clay, and compacted lawn ground even after heavy rain softens the base. Galvanized steel with a rust-resistant black coating resists corrosion through rainy springs and snowy winters, and the steel still bends to match round beds, square corners, and winding paths without cracking. The 29.98 lb. (13.6 kg) 4-pack lands the heaviest in the color lineup to match the taller height, and 4 included clips plus installation gloves help connect pieces without a separate hardware shop trip (note: nails not included). Model ZY-40X12-4Black. Ideal for raised-bed gardeners, hardscape installers retaining river rock, commercial landscapers building driveway borders, and homeowners defining a formal front-yard line. Color: Black powder-coated galvanized steel.
