How to Get It

Product Overview

Pressure-treated timbers are treated for protection against termites and rot. Ideal for a variety of applications including decks, play sets, walkways and landscaping 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.

          The wood served the purpose for my outdoor cactus trellis, however, there were a lot of knots in the wood, which made it difficult to place the screws where they needed to be placed. I did not pick out the wood myself; I ordered online and picked up in the parking lot, so one of the employees actually filled the order inside the store. Perhaps if I had selected my own pieces of lumber, I could have chosen some with less knots.

            The 4x4 was picked out for me and it was the most crooked twisted 4x4 I’ve ever seen. Had as very difficult time trying to put the mailbox post over it. Dissapointed.
