Black Locust Lumber transformed Black Locust from a traditional agricultural material—once used for fence posts and firewood—into a complete architectural product line. For over 25 years, we’ve led its evolution into premium siding, decking, and paver applications, positioning it as a true domestic alternative to tropical hardwoods.As a U.S.-based, fully integrated sawmill, we work exclusively with Black Locust. Sourced from the Appalachian region and crafted by skilled local craftsmen, every step of our process is focused on refining and elevating this single species—bringing it to the forefront of modern architectural design.
Our mission is to elevate a native U.S. species—long trusted by farmers for its strength and durability—into the forefront of modern building. We are committed to educating the market on Black Locust as a high-performance alternative to tropical hardwoods, while championing real, natural wood over composites and energy-intensive modified materials. By advancing its use in decking, siding, and outdoor design, we aim to redefine how architects and builders specify wood—grounded in authenticity, longevity, and American-grown craftsmanship.
