About Pressure Treated Lumber...
Pressure Treated Lumber is the material of choice for both Contractors and "weekend warriors" for deck projects exposed to damaging weather conditions including heat and humidity, damp, mold, termites and other wood destroying insects. This economical building material offers all the benefits of wood plus a built-in resistance to decay, rot and insect damage.
Pressure treated lumber is made from high quality Southern Yellow Pine for it's load bearing strength and superior ability to accept treating.
Pressure treated lumber is used whereever lumber comes in contact with the ground and should be used in all deck framing.
