Engineered to Perform: I-Joists for Superior Wood Framing

Gone are the days of relying solely on heavy, inconsistent lumber. I-Joists bring a modern solution to today’s building challenges. These high-performance framing products are changing the game for builders looking for speed, strength, and precision. 

How I-Joists Outperform Traditional Lumber

Unlike solid sawn wood, wood I-Joists are manufactured with accuracy and engineered layers. This design enhances their load-bearing capacity while reducing the chance of shrinkage, warping, and twisting. Every joist delivers consistent strength across all applications. 

Strong, Silent Floors

Nobody wants to walk across a floor that bounces or squeaks. With wood I-Joists, you get a solid feel and reduced deflection. Their stiffness helps create smooth, even floors that feel premium—and remain that way for years to come.

Reliable Support for Every Roof

The roof is one of the most important structural elements of any building. When used as roof joist, I-Joists offer unmatched reliability. Their ability to span long distances makes them perfect for large open-plan designs without needing extra supports.

Lightweight and Easy to Use

Time is money on a construction site. One reason builders prefer I-Joists is because they are much lighter than traditional lumber. Crews can move them easily, frame faster, and reduce physical strain—while still delivering rock-solid results.

Built to Your Blueprint

Whether you're working on a residential or commercial project, I-Joists can be customized to meet your exact needs. Red-I Joists are available in custom lengths—up to 80 feet—and can be manufactured with parallel or tapered profiles to match any architectural design. 

Preventing Costly Issues Later

Building with poor framing can lead to long-term issues like sloped floors or cracked drywall. Wood I-Joists resist these problems thanks to their high dimensional stability. Builders can trust that their projects will look good and stay safe for years.

Sustainable and Efficient Choice

In addition to performance, I-Joists are a smart environmental choice. They use less raw wood and rely on engineered products, maximizing material efficiency. Less waste, better strength, and sustainable sourcing make I-Joists the future of responsible construction.
