The Evolution Steel Deck Rim Joist is a structurally engineered perimeter member designed to provide strong, stable support around the edge of your deck framing. Made from high‐strength galvanized 16‐gauge steel with a textured black powder‐coat finish, these rim joists resist warping, rotting, splitting, pests, and decay — delivering long‐lasting performance in outdoor environments where traditional wood framing can fail. Available in a pre‐punched profile for 16′′ on‐center spacing, this rim joist measures approximately 2′′ wide × 6′′ high and comes in standard 8′ length, making it easy to install and integrate with Fortress Evolution steel framing components. It provides a flat, rigid edge to attach decking, fascia, or trim, while enhancing the overall stability and rigidity of your deck structure. Ideal for both residential and commercial deck builds, this rim joist offers a low‐maintenance alternative to wood that withstands harsh weather and helps ensure your deck framework remains level and reliable for years to come.
