I-Joist Floor Systems

Durable and Reliable Floors Designed to Last

Say goodbye to warped, crowned, or shrinking floors. When building high-performance structures, selecting the right materials is critical. At Pacific Truss, we prioritize quality by using top-tier engineered wood products for every project. One of our top recommendations for optimal strength and efficiency is the TJI® I-joist. Here’s why it’s our preferred solution..

What Are I-Joists?

I-joists are an essential component of modern flooring systems and roof framing. They are made from top and bottom flange materials, typically composed of Laminated Veneer Lumber (LVL) or Structural Composite Lumber, connected by a web made of Oriented Strand Board (OSB). This unique combination creates a lightweight, cost-effective, and incredibly strong product. These characteristics make I-joists ideal for applications such as floor joists and ceiling joists.

Benefits of Building with I-Joists

Superior Strength and Stability

I-joists deliver exceptional strength with the ability to span long distances without sagging, minimizing the need for load-bearing walls. This makes them perfect for creating open floor plans and spacious designs. Manufacturers provide specific floor joist span tables to guide proper usage, ensuring structural integrity that complies with building codes.

Consistent and Reliable Sizing

Unlike traditional dimensional lumber, I-joists are precision-manufactured for uniform size and shape. This eliminates common issues such as warping, twisting, or crowning, creating a more stable foundation for flooring systems. The consistency reduces unexpected delays or callbacks related to misaligned joists during installation.

Environmentally Friendly

I-joists are an efficient and sustainable choice for construction projects. Manufactured primarily from fast-growing, renewable wood resources, they have a lower environmental impact compared to traditional building materials.

Flexible Design Options

Versatility is a core strength of I-joists. Their design accommodates various applications, from floor and roof framing to more complex structural systems. The flanges provide reliable support, while the OSB webbing enhances stability, making them suitable for both residential and commercial construction projects.

Pacific Truss and TJI Joists

At Pacific Truss, we rely on TJI® I-joists to ensure high-quality and robust construction outcomes. Our expertise lies in designing and fabricating custom floor truss systems tailored to each project’s unique specifications. By incorporating TJI® joists into our projects, we provide our clients with durable, high-performance flooring systems capable of meeting the demands of modern design.

Why Choose TJI I-Joists?

Outstanding Stability

TJI joists maintain exceptional dimensional stability across longer spans, preventing issues like warping, twisting, and shrinking. This ensures quieter, smoother floors that enhance comfort and quality for occupants.

Precision Manufacturing

Every TJI I-joist used in our projects benefits from advanced precision engineering, ensuring long-lasting reliability. From cutting-edge coating technology to meticulous construction, these joists resist the challenges of crowning and shrinking, offering peace of mind for years to come.

Simplified Installation

TJI joists are both lightweight and offered in extended lengths, making them easier to handle and install. This efficiency speeds up project timelines and reduces costly callbacks, helping to save time and money.

Versatile and Customizable

TJI joists are incredibly adaptable, allowing plumbers, electricians, and contractors to easily drill or cut them for utility installations like ductwork and pipes. The TJ-Pro® Rating System even allows for customizable floor performance tailored to specific project needs.
