Wood Treatment Process

YellaWood® accepts only the highest-quality yellow pine to undergo the preserving process.

Wood is an economical and renewable resource. However, when left untreated, it is subject to attack by insects, rot and decaying fungi. You can protect your wood project in a number of ways, but none ensures the long-term protection that pressure treating offers.


When the lumber arrives at our plant, we check the load for quality and then it is loaded into a giant cylinder. A waterborne, copper-based solution is forced deep into the cellular structure of the wood. Under tremendous pressure, the liquid enters the wood to protect against bacteria, fungi, insects and marine organisms that normally feed off its fibers. After several days of drying and another quality inspection, the treated lumber is ready to be delivered to retailers.


At YellaWood®'s treatment facilities, we go to great lengths to ensure that the product we ship is of the highest possible quality. All of our plants have enclosed warehouses ranging in size from three-and-a-half to five acres, protecting the pressure-treated lumber from the sun and rain. Lumber is checked three times for quality: when it arrives at our plants, after we treat it, and before it's shipped.
