The Patriot Docks Aluminum Dock Decking Panels are engineered for dock owners who want a surface that's durable, lightweight, and built to last-season after season. These 4ft. x 4ft. panels drop directly into Patriot Docks frames or can be bolted to most existing dock systems for a full decking upgrade. With a powder-coated finish, ribbed surface, and extruded design, these panels offer a secure footing, a classic dock appearance, and zero upkeep. Whether you're building a new dock or upgrading an older one, aluminum decking gives you the strength you need without the weight or maintenance of wood. Weight: 25 pounds Dimensions: 47-5/8in.
