Strength Where it Counts

Give your customers the quiet, stable floors they want without sacrificing the strength, spans, and ease of handling you need.

Product Overview

floor framing with Boise Cascade BCI joists

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.

BCI Joist Benefits:

  • Greater strength = longer spans
  • Lightweight for easier handling
  • Engineered and manufactured for consistency
  • Use with Boise Cascade software for engineering analysis
  • Forest-friendly sustainability
  • Flanges made with industry-leading Versa-Lam® LVL
“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
