The weight of pressure treated lumber depends on how much time has gone by since the wood was treated, as well as the size of the board or post. Most pressure treated lumber is made from southern yellow pine, which is a relatively heavy wood to begin with, so pressure-treated wood does tend to be heavier than most other lumber because of this alone. But the weight that people really notice when it comes to treated lumber is the water weight that the wood picks up while being treated. The same board will only weigh around 23 pounds after it has had time to dry out. The following table provides the heaviest approximate weight dead load , self-weight per linear foot of pressure treated lumber. The weight values we provide are for the wood immediately after being treated, for the wood after it has dried thoroughly, and for untreated wood with the same dimensions. The values given are for one of the densest wood species, longleaf pine southern yellow pine, longleaf , commonly used to produce pressure treated lumber. This table is intended to give you an idea as to what pressure-treated wood might weigh at its heaviest. For an explanation of the difference between nominal lumber dimensions and actual dimensions, see our Lumber Dimensions Table. There are a few different sub-species of southern yellow pine, with different wood densities.
