4 x 4 x 8' Sienna Pressure Treated Lumber

Build your ultimate outdoor oasis with environmentally certified MicroPro Sienna® so you can rest easy knowing your project will withstand the challenges thrown by Mother Nature. The wood is treated using patented MicroPro® micronized copper azole (MCA) which provides protection against rot, decay and termites – without any of the solvents used by traditional pressure treated wood products. MicroPro Sienna®’s signature rich warm brown tone enhances the wood grain and provides a beautifully finished look to decks, pergolas, fences, docks and any outdoor build you’ll be proud of for years to come.
