There has been pressure-treated wood now for nearly 70 years. Pressure-treated wood is softwood lumber, typically southern yellow pine, that's been chemically treated to last against degeneration and rotting.

The boards are rolled into giant pressurized tanks where chemical preservatives are forced deep into the wood's fibers. The result is an exterior-grade wood that's ideal for building decks, fences, sheds, picnic tables, swing sets, and other outdoor projects.

Pressure-treated lumber may be a good option to be used in the structures of your construction, since it strong and very durable against rotting effects, fungi and insects. It might not be the most elegant looking wood, so it also fits fine out of eyes. It is also not as costly as other lumber such as cedar or redwood.

Pressure-treated lumber is ranked based on how much of preservative is retained in the lumber. The more it is being treated, the better the protection. Pick boards with the preservative focus ideal for their use.

There are typically three categories determining the amount of preservative to be used in different situations.

Above-ground use (.25, sometimes .15 pounds of preservative retained per cubic foot of wood). Should be used where it wont touch the ground. Good for fences, decking and railing.

Ground-contact usage (.40 pounds of preservative retained per cubic foot of wood). Can directly touch ground. Good for beams, posts and decking.

Below-grade (.60 pounds of preservative retained per cubic foot of wood). Usually used for support posts that are partially buried below grade and for permanent wood foundations and planters.
