This brown treated wood is indispensable for any building project. Its 6-inch square base makes it strong, and it's sturdy enough to use in a variety of applications including posts for fencing, deck support, and landscaping. The pressure-treated wood is rot and insects resistant which extends its usable life. The wood has a rich, deep colour, and does not require staining, either for aesthetic or weatherproofing purposes. A simple application of a wood preservative every year is usually all you need. If you plan to cut the treated lumber to a shorter size, just be aware that your new ends require treatment to enjoy the same protection as the rest of the wood surface.
