MacLean Power Systems Buys Dotson Iron Castings

May 22, 2023
The power-transmission components manufacturer acquired the ductile iron parts supplier in a vertical integration move.

MacLean Power LLC – a manufacturer of engineered for electric utility, communication, and civil infrastructure – has acquired Dotson Iron Castings in a private transaction. The 147-year-old Minnesota foundry will become an operating unit of MacLean Power, whose CEO described the purchase as part of the group’s “vertical integration strategy, allowing us to serve our customers’ needs more effectively and continue to expand our ability to provide a growing number of American manufactured products.”

Other terms of the acquisition and future plans for the Dotson Iron operation were not released. Dotson CEO Tyson Twait will join MacLean Power as vice president and general manager of its Mankato Operations.

“I am very excited about the opportunity this brings to Dotson. MPS’ dedication to its facilities, employees, and safety will be of great benefit to our existing workforce,” Twait stated, according to a joint release.

Dotson Iron has been a supplier of transmission hardware and fiberglass cross-arm brackets to MPS, which noted that its customers and end users in those markets will benefit from shorter lead-times and increased production capacity.

As a manufacturer of poleline hardware, insulators, arrestors, connectors, anchors, cross-arms, and other related products, MacLean Power Systems operates an aluminum foundry in Alabaster, AL. The company was founded in 1986, and in October 2022 its owners MacLean-Fogg Holdings sold a majority stake in the business to private-equity group Centerbridge Partners for an undisclosed price.

“We are thrilled to welcome Dotson to the MPS team,” stated MacLean Power Systems CEO Steve Scharnhorst. “As an existing vendor to MPS, our partnership with Dotson has flourished over the last several years. Dotson’s excellent performance as a supplier, including the quality of their product, and best-in-class foundry process are really what drove us to this partnership.

He added: “However, what is most advantageous about Dotson is their talented and knowledgeable team. Each and every dedicated individual at Dotson has worked to make the business what it is today and they will continue to be their essential element. We have great potential to integrate with all our existing facilities.”
