KDAT Brown Treated Wood

MicroPro MCA Brown Treated Wood Products from Northern Crossarm provide rich, beautiful, natural wood tones and a finished look.

KDAT (Kiln Dried After Treatment)

Kiln Dried After Treatment, or KDAT is a process that removes excess moisture from lumber, minimizing the tendencies of wood to shrink, cup and warp.

Northern KDAT Decking

Uniquely designed in-house for superior stability while stress relief cuts help maintain a smooth, even surface.

Revere Deck Framing

Revere is the finest KDAT deck framing. Made for both composite and wood surfaces, it’s more stable, so you can focus less on deck warps and callbacks, and more on the quality of your deck builds.


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?
