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.
