18" RFPI-900 I-Joists are supplied through our Boise, Idaho lumberyard for construction projects throughout the Treasure Valley. The RFPI-900 series is the industry-recognized equivalent to Weyerhaeuser TJI-560 and Boise Cascade BCI-90 2.0 I-joists and can be used as a substitution where those joist series are specified. Featuring massive 3-1/2" LVL flanges, these heavy-duty engineered floor joists are designed for demanding long-span applications requiring increased stiffness and higher load capacity. I-joists provide improved dimensional stability compared to dimensional lumber while reducing shrinking, warping, and floor movement.
Delivery Options
