Kiln Dried After Treatment (KDAT) wood is pressure treated lumber that’s been dried after the pressure treating process to deliver better resistance against warps, cups, twist and checks.

what separates us from the green/wet lumber guys.

The KDAT Difference.

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