A longtime Darlington, Wis., lumber supplier has been acquired by an Iowa company. Nodolf Lumber recently was acquired by MetalTek, a division of Elma, Iowa-based Busti Lumber. Together, the two divisions will operate as a “one-stop shop” for building material needs in southwest Wisconsin. The acquisition marks a major step for a southwest Wisconsin business whose roots date back more than 100 years. Conversations about a potential acquisition began late last year. Busti Lumber already had acquired MetalTek in Monroe, Wis., and Nodolf Lumber seemed a natural complement. Conversations moved “very quickly,” and the acquisition was finalized in early January. The Darlington location will now serve as the customer service hub for both Nodolf and MetalTek, although MetalTek will continue its manufacturing operations in Monroe.
