Landscape timbers are a fantastic way to outline any mulch bed or children’s play area. We stock two different sizes of Natural Select Wood landscape timbers in the yard, but are also able to special order large quantities of their other products. They come in 5.5×5.5×8 and 5.5×7.5×8 and are backed by a lifetime limited warranty. Our timbers are pressure-treated. This method protects wood against rot, decay and termite attack. Treated lumber is safe for both your family and the environment. Natural Select Wood products are treated with copper and azole instead of the poisonous copper, chromium and aresenate (the chemical found in rat poison). Their superior protection against decay has allowed Natural Select to be the standard for commercial building in Europe and every other continent where concerns about toxicity exist.
