from their website.....
Black Locust Lumber U.S.A., is the nation's leader in creating custom finished wood products from domestic Black Locust wood. The naturally rot-resistant wood is a sustainable alternative for chemically-treated lumber and endangered tropical hardwoods. Black Locust’s durable composition lends itself to be a “lifetime” application; it is not uncommon for the wood to last beyond 50 years. Requiring little to no maintenance, Black Locust is the ideal building material for custom projects including, but not limited to decking, fencing and site-furnishes. With the capability in place, consistent resources and inventory in stock, Black Locust Lumber, U.S.A. can satisfy projects with extensive, high-profile demands.
