Why Choose KDAT Vs. Pressure Treated Lumber?

Kiln Dried 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?
