GRAND RAPIDS, Mich. — ProWood, a part of UFP Industries, Inc., is expanding the availability of its TrueFrame Joist, the first product of its kind in the new enhanced treated lumber category. Previously available in Colorado and across the Great Lakes and Midwest states, TrueFrame Joist is now available throughout the Northeast and South Atlantic.

TrueFrame Joist is built to deliver consistently straight, stable performance, helping deck builders reduce jobsite variability and achieve predictable results build after build, the company says.

"TrueFrame Joist reduces the variability inherent in the deck framing process, so crews can move faster and install with greater confidence and predictability," said Luke Snyder, product manager at ProWood.

Each TrueFrame Joist is manufactured from #1 grade Southern Yellow Pine, infused with proprietary next-generation stabilizer additive, kiln-dried after treatment (KDAT) for improved stability and easier handling, and factory-planed to within 1/16 inch for flat edges and consistent sizing.

TrueFrame Joist is:

• Backed by a Limited Lifetime Warranty
• Manufactured to meet UC4A Ground Contact standards
• Available in nominal 2x8-, 2x10-, and 2x12-inch lengths of 12, 14, 16, and 20 feet (Actual sizes: 1 1/2x7, 1 1/2x9, and 1-1/2x11 inches)
• Color-infused for lasting beauty with no staining or sealing required at installation

"TrueFrame Joist bridges the gap between traditional treated lumber and other framing alternatives," said Ashley VanderWall, brand marketing manager at ProWood. "It's a practical solution for quality-focused deck builders who want elevated performance without an over-engineered substructure."

Sean Collinsgru, ProWood ambassador and owner of Premier Outdoor Living in New Jersey, sourced TrueFrame Joist for his latest decking project. He says the product's light weight and consistent sizing made framing easier and faster for his crew. He plans to use it for all his projects in 2026.

"There's been so much talk in the industry over the last few years about alternative framing options," Collinsgru said. "But ProWood took a time-tested, sustainable, and economic material and made it better."
