TJI® Joists

TJI® Joists

Trus Joist developed the wooden I-joist 50 years ago and Weyerhaeuser continues to build on that legacy. Engineered to provide strength and consistency, these joists are a key part of making a high-performance floor. The dimensional stability of Trus Joist TJI joists help them resist the warping, twisting, and shrinking that can lead to squeaky floors. TJI joists are light weight and come in long lengths, which makes them faster and easier to install than traditional framing and saves you both time and money.

Chosen for 14 Straight Years

For 14 years straight years, TJI joists have been recognized by readers of Builder Magazine as the “most-often-used engineered I-joist.” The results are from a survey of 10,800 builders, builder-developers and general contractors in the U.S.

With TJI joists, you get more than just a great product, you also get decades of research and real-world experience. All this results in better performing floors that use fewer trees while also reducing jobsite wood waste. It all starts with Trus Joist TJI joists.
