Superior Framing Starts with Wood I-Joists

Today’s builders demand precision, efficiency, and durability—and wood I-Joists deliver all three. Whether you’re designing a home, office, or warehouse, these engineered joists are built to outperform standard lumber at every level of construction. 

What Sets Wood I-Joists Apart

The key advantage of wood I-Joists is consistency. Traditional framing lumber often has knots, warps, or splits. I-Joists are manufactured in controlled environments, ensuring each piece meets strict performance and dimensional standards for strength and straightness.

Floor Systems That Stay Flat

Flooring built on I-Joists resists sagging, bouncing, and squeaking. The engineered stiffness of each joist helps distribute loads evenly. This creates quiet, level floors that feel solid underfoot—and that kind of quality is something homeowners notice immediately. 

Roof Joists That Carry the Load

When used as roof joists, I-Joists provide excellent load-bearing capacity. They handle the stress of heavy shingles, snow accumulation, and even rooftop equipment. Their strength-to-weight ratio makes them an ideal choice for both residential and light commercial roofing systems.

Easier Handling, Faster Installs


Construction schedules are tight, and labor costs are high. I-Joists reduce time on-site by being easier to move and install. Crews can carry them without equipment and fit them quickly into place, which helps speed up framing and move projects forward faster.

Customization for Any Build

Red-I Joists are custom-made to your project’s exact specifications. Whether you need 20 feet or 80 feet, parallel or tapered profiles, you’ll get the right size every time. This precision means fewer adjustments, better alignment, and less waste on site. 

Stability Through the Seasons

As the weather changes, so does traditional wood. It shrinks, expands, and moves. But wood I-Joists are built to remain stable. They resist moisture-related changes, helping your structure stay sound and reliable year-round.

Smarter for the Environment

Engineered wood products like I-Joists use fast-growing trees and optimized wood fibers, which helps conserve old-growth forests. They also create less scrap, making them a smarter, greener choice for today’s eco-conscious builders and homeowners.
