LeClaire Manufacturing is just the present chapter in a remarkable history of the Zimmerman family. Metals have been the foundation of the family business dating back to the 1890’s. That is when Wm. C. F. Zimmerman introduced the Mighty Monarch Stump Puller – a grey iron casting. Growth was rapid and in 1915 the family built a new “modern” steel foundry in Bettendorf, Iowa. Immediately the Zimmerman Steel Casting Co. began building a reputation for high quality castings.

This reputation was recognized by the U.S. government as preparations were being made for entry into World War II. The Zimmerman Steel Casting Co. became a major defense contractor and winner of the prestigious E Award, for outstanding contributions to the World War II manufacturing efforts. Although the family sold the Bettendorf foundry after the war, Robert Zimmerman, just out of engineering school at Iowa State University, continued the metals business tradition by introducing aluminum to the family history. He purchased LeClaire Manufacturing in 1966 and the company has been in the growth mode ever since. Today, we supply high quality aluminum castings to customers world-wide.
