What Is Pressure-Treated Lumber?
Our pressure-treated lumber is engineered to resist rot, decay, and insect damage so your projects stay strong and dependable, season after season. Using a specialized pressure-treatment process, protective preservatives are driven deep into the wood fibers to strengthen the lumber and extend its lifespan. The result is reliable, long-lasting performance you can count on for any outdoor build.
