Red-I™ Joists

Red-I joists: structural solutions

Developed to provide strength and consistency, Red-I joists have become an integral part of floor, ceiling, and roof framing.

Built with dimensional stability, Red-I joists resist warping, twisting, and shrinking that can lead to squeaky floors.

Highly customizable, these strong and lightweight engineered I-joists include a wide range of sizes and depths in lengths up to 80 feet, providing extraordinary design freedom. Plus, they’re faster and easier to install than traditional framing, so you save on labor.

High-quality, manufactured engineered wood.

Red-I joists are manufactured using high-quality, engineered wood—including LVL flanges and RedBuilt’s proprietary OSB web. In addition to the standard parallel flange configuration, some series are available with tapered profiles for added design flexibility.

Offering architects, engineers, building owners, and commercial contractors practical and economical solutions, Red-I joists increase design confidence and building quality.
