Introducing Finger Jointed Black Locust Decking Boards

Black Locust Finger Joint

Introducing Finger Jointed Black Locust Decking: Longer Boards, Seamless Beauty

For years, Black Locust has been a top choice for environmentally-conscious architects, homeowners and builders seeking a durable, natural hardwood for outdoor projects. As a naturally rot-resistant alternative to tropical hardwoods, synthetic products, and pressure-treated lumber, Black Locust has long been admired for its sustainability and strength. However, the main drawback from customers has been the board lengths. What helps make Black Locust so sustainable – its fast growth and tree longevity –  also means a lack of consistently available longer boards.

That challenge is now a thing of the past.

We are excited to introduce finger jointed Black Locust decking, offering board lengths of up to 20 feet! This innovative approach transforms Black Locust from a length challenged option into the ideal choice for those who want both sustainability and an easy-to-install product.

What Is Finger Jointing, and Why Does It Matter?

Finger jointing is a precision woodworking technique that joins shorter pieces of lumber together using interlocking cuts and exterior marine grade glues. It creates strong, seamless bonds. This method has been successfully used in high-performance interior wood products for years. And now, it brings new possibilities to Black Locust.

With finger jointed Black Locust; architects, homeowners, and builders no longer have to settle for shorter boards. Instead, they can enjoy the beauty and consistency of longer planks while maintaining the structural integrity and natural benefits of solid Black Locust.

The Benefits of Finger Jointed Black Locust Decking

  • Longer Board Lengths: Say goodbye to excessive seams! Now available in lengths up to 20 feet, our decking offers a cleaner, more seamless look for decks, boardwalks, and other outdoor applications.
  • Sustainable: Black locust is a hardwood that grows quickly and regenerates naturally, making it the most sustainable wood choice available. Finger jointing also reduces waste by utilizing shorter pieces of lumber that might otherwise be waste.
  • Strength & Durability: Finger jointed Black Locust retains the superior hardness and natural rot resistance that make this wood so desirable. The joints themselves are engineered for high strength, ensuring long-term performance, with no loss in the strength of the wood (View the full strength test report on our technical resources page).
  • Enhanced Aesthetics: The ability to use longer boards means fewer breaks in your deck surface, creating a more polished, high-end appearance that many homeowners and architects prefer. For installers, this means a much faster installation using longer lengths, and fewer end cuts.

Why This Is a Game Changer for Outdoor Projects

For those who love the benefits of Black Locust but have hesitated due to length limitations, this is the breakthrough you’ve been waiting for. Now, you can build with a natural, hardwood deck without sacrificing design preferences. Whether you’re constructing a sprawling deck, a beautiful pergola, a commercial boardwalk, or siding/cladding, finger jointed Black Locust offers the best of both worlds—natural beauty and extended functionality.
