This brown treated wood is a versatile piece of lumber. At 1 inch thick, it's ideal for use as a fence panel or in other applications where it won't need to support significant weight. The pressure-treated wood undergoes a special process that leaves it protected from weather, rot, and insects. The brown colour is attractive, and the lumber is ready to use without the need to stain it. Apply a clear preservative once a year. It's the only maintenance that you need with treated wood. Be aware that if you cut it to a shorter length, the new exposed ends require an application of treatment to have the same level of protection as the rest of the wood surface.
