Red-I™ I-Joists

Forty years ago, our founders developed the engineered wood I-joist. Engineered to provide strength and consistency, Red-I™ I-joists have become an integral part of floors, ceilings and roofs in commercial applications. The dimensional stability of Red-I™ I-joists helps them resist the warping, twisting, and shrinking that can lead to squeaky floors. Red-I™ I-joists are strong yet lightweight and include a wide range of sizes and depths in lengths up to 80 feet, giving you extraordinary design freedom. Because they're faster and easier to install than traditional framing, you save on labor.

Red-I™ 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. Camber is also available in some series, upon request. Red-I™ I-joists offer architects, engineers, commercial building owners and commercial contractors practical and economical solutions for virtually every structure, while increasing design confidence and building quality.
