“I consistently hear from our framer and trade partners that Boise Cascade is always the preferred vendor. It’s about product availability without delay, competitive pricing, engineer support as well as value engineering to produce efficient layouts and plans. They just continue to be the preferred vendor and in turn my preferred vendor because of the relationship value they provide.”

High Performance Results
AJS Joists’ longer lengths mean simpler floor/roof layouts and higher floor performance. Plus, AJS joists are consistent from piece to piece, helping to keep floors flat and quiet making customers happy.
Easy Installation
AJS Joists are lightweight and feature solid lumber flange for easy handling and installation. The joists’ 1-1/2″ pre-stamped knockouts and allowances for on-site hole cutting provide for easy routing of wiring, HVAC, and plumbing through the web, speeding construction and reducing labor costs.
All AJS Joists are field trimmable without the need for special tools or skills, and eased edges mean fewer splinters on the job.
