RFPI Joist - Solid-Sawn Flange

Proudly Manufactured In The U.S.A

Overview Properties Design Guides Software Tools Sustainability

Roseburg RFPI® I-joists with solid-sawn flanges are used in floor and roof construction and are engineered to make the job easier. RFPI’s are the ideal choice for engineers, specifiers and builders who want to provide their customers with high quality floor systems. They provide consistent performance for the most demanding residential applications. RFPI Joists are an inherently green product because they are a more efficient use of raw materials. To manufacture our EWP products, we use fast growing, under utilized and less expensive wood species; therefore, large old growth trees are preserved. By design, engineered wood products require much less wood to achieve the same load bearing capability of solid sawn lumber.
