THE BEST GETS BETTTER AND DEEPER TOO

TJI® Joists revolutionized the way you build floors.
Trus Joist developed the wooden I-joist 40 years ago and iLevel 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 TJI joists helps 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.

The revolution continues with the introduction of our new iLevel Trus Joist TJI 560D joist. Available in depths of 18", 20", 22", and 24", the TJI 560D joist is a great choice for multi-family and light commercial construction. Readily available through our extensive nationwide network of distributors and dealers, the TJI 560D is there when you need it. For more information, contact your iLevel representative.
