Knowing and understanding the sapwood and heartwood functions and properties are crucial in pressure-treating southern pine. It is very difficult to penetrate heartwood with chemicals. Therefore, knowing heartwood content before treatment will benefit companies in chemical consumption, treating cycles, and, foremost, cost. In this study, two different assessments were conducted in which lumber and pole heartwood/sapwood data was collected from eight treating plants across five Southeastern states. In both assessments, the data indicated some significant differences between similar products from different vendors, but there was no significant difference in heartwood content between plant locations. The results suggested that the amount of heartwood increases as the size and length of the products increase. These findings can argue that the size of raw materials that vendors use and the products they manufacture have more effect on heartwood content than plant location.
