Northern KDAT Decking is uniquely designed by Northern Crossarm Company.

Northern Crossarm’s Northern KDAT Decking boasts a traditional radius edge profile, stress relief cuts and a 1-3/8″ thickness for greater stability. Each deck board is coated in a rich brown finish for a finished look.

Kiln Dried After Treatment Decking

Since wood is porous, it has the natural tendency to warp, cup, twist, crack, check, shrink and swell as it’s exposed to normal wet and dry cycles.

Northern KDAT Decking is kiln dried after treatment, meaning a large percentage of the moisture is removed from the wood to improve both the performance and stability of the pressure treated wood.

Northern KDAT Decking Reviews

We tested the water with Brown KDAT treated wood a few years back and quickly learned that customers loved the benefits of purchasing a finished product. The perceived value of a finished deck is much higher than the actual cost, meaning additional margin opportunity. Since that time, we’ve upgraded to Brown KDAT treated wood and have also expanded our product offering, eliminating some green treated items altogether!

Lamperts of Faribault is now in its fourth year of stocking Northern Crossarm’s Brown KDAT product line. Our builders had no problem with the additional cost of the products when they saw the benefits of the material: less weight and much less checking and cupping. The appearance of the brown stain is more appealing than the green when composite decking is going over treated joists. Northern Crossarm’s Brown KDAT product is still our best selling point.
