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?

About Northern Crossarm

When Joseph Bischel founded Northern Crossarm Co. Inc. in 1922, it is doubtful he ever expected his company to grow from a one-man manufacturing firm into one of the leading wood treating companies in the Great Lake States area. Today, Joe Bischel’s company is owned and operated by his grandson Pat Bischel.  The principles founded by Joseph Bischel in the mid 1920s of honest, hard work, integrity and willingness to serve are the cornerstone of the company’s foundation.  Together with the contributions of its dedicated employees, Northern Crossarm Company exemplifies what it means to be a leader in the industry.
