Kiln Driend After Treatment (KDAT) lumber from Northern Crossarm is the rich, finished brown wood that’s lighter, easier to handle, saw and plane. With minimized moisture content, you get a 100% finished, stable product with the added benefits of reduced warps, cups, twists, checks & cracks common with traditional “wet” or “green” treated lumber. You get the same rot-resistant protection of pressure treated wood, but with the added benefit of drying for improved performance. Are you ready to make the switch to KDAT?
