Plymouth Tube Company has completed the sale of its Winamac, Indiana Carbon & Alloy Seamless Tube Mill to an affiliate of Shadowbriar Capital Partners. Winamac will operate as a stand-alone business named Crossroads Seamless USA.

The Winamac site consists of a Cold Draw, a Hot Mill, and a Quench and Temper line which manufacture carbon and alloy seamless steel tubing for diverse end markets, including construction, drilling, utilities, military, oil & gas, and other industrial applications.

For Shadowbriar, the acquisition represents an exciting opportunity to leverage the growth model it has successfully implemented at its other value added metal processing portfolio company businesses. With 35 years of demonstrated leadership experience in the carbon and alloy steel tube industry, George Thompson has joined Crossroads Seamless USA as the company’s president.

“Crossroads Seamless USA brings an excellent array of hot finished, cold drawn, and tube finishing capabilities and a workforce that is truly exceptional,” Thompson said. “We are very excited to expand the company’s production volumes and processing capabilities to increase the value we bring to customers.”

“Crossroads Seamless USA intends to become a leading domestic producer of carbon steel seamless tubing from the company’s excellent manufacturing facility in Indiana,” said MaƩ Homme, managing partner of Shadowbriar Capital Partners. “We are confident that George Thompson’s strong industry relationships and commercial background will drive significant growth in the years to come working collaboratively with the company’s outstanding workforce and leadership team.”

The sale of Winamac follows Plymouth’s announced closure of its West Monroe, LA site earlier in July 2024 and enables Plymouth to focus on its product leadership strategy targeting core aerospace, defense, medical tubing, nuclear tubing, and fluid power markets. Plymouth emerges in a strengthened position to increase the differentiated value it brings to customers.

“Plymouth is grateful to the Winamac employees who have delivered substantial value for customers and for Plymouth since 1962,” said Paul Lemke, Plymouth’s board chair. “We are excited for its future with Shadowbriar and eager to embark on Plymouth’s second century with a sharpened focus on extending our product leadership for highly demanding specialty markets.”

Stout Capital served as financial advisor to Plymouth on the transaction. Kilpatrick Townsend & Stockton provided legal counsel to the sellers, and McDonald Hopkins provided legal counsel to the buyer.
