This 4 in. x 6 in. x 12 ft. Timber is pressure treated for long life. It can be used for a variety of applications such as for decks, play structures, retaining walls, walkways or other outdoor projects where lumber is exposed to the elements. When used properly, it is both safe and environmentally friendly.Treated wood is typically still wet when it's delivered to The Home Depot or job site. As it dries, you should expect slight changes in width and length. As lumber dries, it may split, cup and warp. This is more likely to occur to occur in lower-grade boards, where knots and uneven grains are already present. Each piece of lumber is unique and carries physical characteristics that may include the following: knots, warping, shrinkage, swelling and/or splitting.
