Pressure Treated Wood

Pressure-treated wood, most often southern pine, is treated with chemicals to prevent decay and insect intrusion. This type of wood is recommended for all outdoor projects with contact between wood and moisture. We treat lumber with the most current generation of Copper Azole (CA) and Copper Chrome Arsenic (CCA), which not only guards against intrusion but adds protection for water repellency. Popular commercial and residential projects recommended for treated wood are; fences, decks, deck furniture, wooden benches, sheds, walkways, handrails, freshwater docks, ramps, porches, and structural framing. 

Preservative Treatment 

Chromated Copper Arsenic (CCA) - water-soluble inorganic pesticide most commonly used as a preservative to make wood resistant to termites and fungi. This type of pressure-treated wood is used in industrial and marine applications, including agricultural posts, poles & pilings. 

Retention Levels


Deck supports, Fence posts, Garages, Trailers, and Sheds


Freshwater, Agricultural buildings, Bridges, or Areas with changing weather conditions. 


Foundation, Poles, and Brackish


Boat lifts, Boat houses, Decks, Docks, Saltwater

Preservative Treatment 

Copper Azole Type C (CA-C) - is a copper-based wood, most commonly used as a preservative to make wood resistant to termites and fungi. This type of pressure-treated wood is used in agricultural & residential projects such as decks, fences, landscaping, boardwalks, ramps, gazebos, bridges, docks, and freshwater structures. It is environmentally safe. 

Retention Levels

Ground Contact

This treatment is designed to protect wood that is exposed to all types of weather. It can be placed directly on or in the ground. Due to its higher chemical retention level, it can last much longer than above the ground wood.

Structural Contact

Above ground wood is treated to a lower standard of resistance. It is formulated to protect against the sun, weather conditions, and insects. It's generally used in applications that are six inches or more off the ground. 

The Treatment Process

At Outdoor Living Products, we treat lumber at our facility. Our technicians are specialists in their field with years of experience, ensuring our treatments guarantee the highest level of protection. The goal of pressure-treating wood is to force the preservatives deep into the heart of the wood. This preservative acts as a barrier between the wood and the outside elements. During treatment, wood is loaded into a horizontal vacuum-pressure cylinder. Once the door is sealed, the vacuum eliminates the air from the cylinder. Next, the liquid preservative solution is precisely pumped in, and the pressure is raised, which forces the liquid into the wood. After the process is complete, our technicians remove the wood from the cylinder. Our mission is to deliver a treatment that withstands the test of time.
