Download specification ↓Black Locust is the go-to choice for builders and designers looking for a long-lasting, low-maintenance decking solution. Naturally rot-resistant and incredibly strong, it holds up in high-traffic environments without the need for chemical treatment. From backyard decks and rooftop terraces to boardwalks, restaurants, and public spaces, Black Locust performs beautifully across a wide range of decking applications. Its golden color and tight grain offer a refined, natural look that weathers to an elegant silvery gray over time. We offer a range of profiles and sizes to fit any deck design — residential or commercial — with the strength and reliability to handle years of foot traffic, weather, and wear. Crafted in the USA from sustainably harvested wood, Black Locust is a smart alternative to tropical hardwoods and composite decking, and built to last for decades.
Decking Sizes & Pricing
We offer Black Locust decking in both 5/4 and 8/4 thicknesses with random lengths as standard. For projects that require specific board runs, we also produce cut-to-length orders in 6', 8', 10', and 12' options. All decking comes milled with an eased edge profile for a smooth, finished look and comfortable foot feel.
Select & Better Mix Grade
Our Select & Better Mix grade is offered as a practical alternative to our premium-grade Black Locust. This secondary grade provides excellent value for projects that still demand quality but are more flexible when it comes to appearance.
Boards in this mix feature one cleaner face with minimal knots and character—comparable to Select grade—while the reverse face meets the standards of a #1 Common grade. You can expect a structurally sound product with solid performance, some natural variation, and more visible character on the non-show face.
This grade is ideal for applications where one face will be visible and the back will be hidden or less critical. It’s a popular choice for decking, siding, fencing, and other exterior uses where durability and sustainability are key—but where a fully premium aesthetic isn't required throughout.
If you’re looking for high-performance Black Locust with more natural variation at a more accessible price point, this is the grade for you.

Black locust wood is exceptionally resistant to decay and insect damage thanks to its high tannin content. This durability makes it a sustainable and low-maintenance option for residential and commercial decking.
The rich, warm hues and unique grain patterns of black locust wood add natural beauty to any outdoor space. Over time, it develops a silver-gray patina, enhancing its appeal and blending with the environment.
