Schillings Standard Pressure-Treated Lumber is ideal for decks, docks, ramps and other above ground projects where lumber is exposed to the elements. It is treated to protect against termites, fungal decay and rot. Our standard treated lumber is kiln dried to prevent any warping or splitting once installed. You can paint or stain standard treated lumber to further customize any outdoor project. All standard treated lumber from Schillings is southern yellow pine.
