About Us

Founded in 1955 by Martin Gorman, Duplex Metals, Inc. is a family run manufacturer's representative agency. "Marty" worked in sales and production for a private foundry located in Lufkin, TX for many years. He had a vision of supplying castings to his many already established customers from several different foundry sources. As the business began to flourish the need for additional support allowed him to bring his son, John Gorman, on board in 1968.  With Duplex Metals home securely in the Midwest, we have grown both domestically and globally.
