Brown Treated Decks from Northern Crossarm
Rich, Brown Treated Decking (Northern KDAT Decking) is lighter in weight, easier to handle and saw and plane. At 1-3/8″ thick, Brown Northern KDAT decking delivers minimized warps, cups, twist and checks, as well as increased deck frame stability.

"Wet" Treated Decks Vs. Our Brown Treated Decks
Wood is a porous material, which makes it ideal for the pressure treating process. Because it is porous, wood has a natural tendency to warp, cup, twist, crack, check, shrink and swell as it is exposed to wetting and drying cycles.
The pressure treating process fully saturates wood with preservatives and water. While the preservative is left in the wood for protection, the water is released as the wood naturally dries, bringing out these natural characteristics.
Kiln Dried After Treatment, “KDAT” is a process that removes this excess moisture from wood introduced by the treating process. Kiln drying after treatment helps to improve the performance and stability of pressure-treated wood.

Northern KDAT Brown Treated Decking
Northern KDAT Brown Treated Decking is pressure treated, dried and coated in a rich brown color that looks great on application. Rather than waiting weeks to paint or stain, our brown treated decking is already “pre-finished”, so you can seal the wood immediately.
Outside of just a prefinished look, brown treated decking from Northern Crossarm is kiln dried after treatment, meaning its moisture is removed as close to 19% moisture content to reduce some of the biggest headaches associated with “green” or “wet” treated wood. Less cups, warps, cups, checks and drying time.
