McArthur Lumber And Post is your leading wooden fence treating facility. Not only do we promise competitive prices but, we also include a 30 year warranty with our posts. All of our fence posts are dried to a required moisture content before treatment takes place. This ensures the wood is conditioned for penetration of our chemical to meet the standard retention set forth by American Wood Preservative Association (AWPA). All of our posts are pressure treated, forcing the chemical into the sapwood. After every treatment process we conduct testing, making sure the correct amount of chemical is in every post.
