Now available: Trex Select® and Trex Transcend® Lineage® 12’ square edge decking boards for flexible, precision builds.

Trex Expands Lineup with 12′ Square Edge Boards

Trex has expanded its product offering to meet the growing demand for more adaptable decking solutions. For the first time, both the Trex Select® and Trex Transcend® Lineage® collections now include a 12’ square edge board option. This new addition is designed to give builders greater flexibility when working on projects that require precise cuts, specific layouts, or limited space.

The 12-foot square edge board fills an important gap in the current lineup. It provides a practical solution for smaller decks, docks, and repairs – where longer board lengths may result in unnecessary waste or added labor. Contractors can now order exact lengths that better match the scope of work, helping reduce excess material and streamline installation.

This update reflects Trex’s continued commitment to offering high-performance, low-maintenance products that evolve with industry needs. With consistent quality and trusted durability, these new boards are a smart option for professionals focused on efficiency, precision, and long-term value.

What’s New in the Trex Decking Lineup?

The latest product update from Trex adds a strategic new length to two of its most trusted collections. The newly introduced 12’ square edge boards are now part of both Trex Select® and Trex Transcend® Lineage®. These additions are designed to meet the evolving needs of professionals who rely on high-quality materials that support tighter project planning and faster installs.

The shorter, square edge format offers more precision in deck layout, particularly for areas with structural limitations, multiple elevation changes, or customized framing plans. By expanding these product lines, Trex has provided more control over board placement, which can lead to tighter seams, fewer cuts, and a cleaner visual finish.

Trex Select® now offers a 12’ square edge profile, adding an important option to this dependable and cost-effective collection. While longer boards work well for large decks, they can be excessive in projects that require short runs or replacement sections. With the addition of this new length, contractors can align deck plans more efficiently with fewer leftover materials.

This is especially useful for builders working with perimeter details, picture framing, or stair landings – where shorter boards are often more practical. The square edge profile also provides a finished appearance without the need for concealed fasteners, saving both time and labor on installation.

By introducing this new board size, Trex Select® becomes even more adaptable without compromising its proven durability or performance.

Trex Transcend® Lineage® Now Available in 12’ Square Edge Format

The premium Trex Transcend® Lineage® collection also receives a major update. All colors in the Lineage® line are now available in 12’ square edge boards, offering enhanced layout flexibility for luxury outdoor spaces. These boards continue to feature SunComfortable™ technology, which reduces surface heat and supports more comfortable use in sunny areas.

The new 12’ length allows for greater accuracy when managing inlays, board transitions, or framing elements that require shorter segments. Contractors can now build intricate designs without depending solely on larger, pre-cut boards.

For clients seeking a cooler surface, high-end finish, and reduced material waste, the 12’ Lineage® square edge board provides a smart, performance-driven solution that supports modern design standards.

Why Choose 12’ Square Edge Boards?

The new 12’ square edge boards from Trex offer more than just a shorter length. They bring added flexibility, better material management, and more precise design options to both the Trex Select® and Trex Transcend® Lineage® collections.

Here’s how they make a difference:

  • Optimized for Smaller Layouts – Ideal for decks with short runs, repairs, or unique framing where 16’ or 20’ boards are too long.
  • Less Waste, More Control – Reduces leftover cuts and over-ordering by allowing contractors to choose the exact lengths needed.
  • Easier to Handle On-Site – Shorter boards are easier to move, load, and install—especially on tight jobsites or multi-level builds.
  • Fast Installation – The square edge format allows for face-fastening, which can speed up installs in framing, stair, or border areas.
  • Refined Design Options – Perfect for creating clean picture frames, deck edges, or transitions without cutting down longer boards.
  • Seamless Aesthetics – Supports tighter seams and more consistent board placement, resulting in a cleaner visual finish.
  • Same Durability and Performance – Backed by the same warranties, fade and stain resistance, and low-maintenance promise you expect from Trex.

With this new format, Trex continues to deliver high-performance decking products that support smarter planning, cleaner execution, and more professional results.
