Give your customers the quiet, stable floors they want without sacrificing the strength, spans, and ease of handling you need.
High-performance floors start with BCI® Joists. With 20% greater strength than comparably-sized dimensional lumber, BCI Joists allow for long spans with little to no twisting, shrinking, or bowing. The result? Consistency and performance from piece to piece, keeping homes square, floors flat and quiet, and — most importantly — the builder’s reputation intact.
Available in standard depths ranging from 9 ½″ to 20″ providing the long spans needed for your next project.

“Boise Cascade I-Joists and Versa-Lam LVL beams are designed to hold more weight per square foot than some others out there, and we've lost jobs before because someone substituted with an inferior product.”
President - Lumber & Supply Dealer
BCI Joists make it easy and cost-effective to reduce floor vibration and improve customer satisfaction. No more bounce. No more squeaks. Just quiet, solid floors that stand the test of time. Better yet, with the help of Boise Cascade® software suite, you can design, size, and analyze with just a few clicks.
