These deck balusters are designed to upgrade wood or composite deck and stair railings with a durable aluminum alloy build. The black powder-coated finish is made for long-term outdoor use and helps resist warping, rust, and corrosion. Each baluster comes pre-drilled for easier installation, and the set includes screws for fastening to wood or metal frames. The wave-curved shape adds a decorative look while helping create a secure railing system. Suitable for decks, stairs, porches, yards, and balconies.
