How is Pressure-Treated Wood Made?
The wood to be treated is entered into a large chamber or tank which will then be filled with the chosen chemical agent to treat the lumber. The tank then gets pressurized which forces the chemical to be absorbed deep into the wood fibers. When within the wood fibers, the chemical coats the material heightening the moisture-resistance of the wood inside and out.
Types of Wood Treatment
Originally the most common chemical combination used to treat lumber used to be chromated copper arsenate. In 2003, however, the EPA wisely stepped in to restrict the use of arsenic due to health regulations as treated lumber is often used in residential settings.
- Alkaline Copper Quaternary (ACQ)
- Sodium Borate (SBX)

Uses for Treated Wood
