Our History

Founded in 1954 and based in Chicago, Illinois, CMC is a private company and is the parent company of numerous wholly-owned subsidiary manufacturing companies in the building and industrial products markets in North America.

1954
Continental Materials Corporation (“CMC”) was founded in 1954 under the name of Continental Uranium, Inc. by members of the Gidwitz family of Chicago as part of the post-war boom in locating and harvesting domestic uranium deposits and was publicly listed on the American Stock Exchange. CMC quickly diversified and acquired Transit Mix Concrete of Colorado Springs, a supplier of aggregates and ready-mix concrete materials, in 1956 and Williams Furnace Company of southern California, a manufacturer of wall furnaces in 1958. Over the next twenty-five years, CMC shed the uranium mining operations and achieved growth through the acquisition and integration into Transit Mix of various aggregates, concrete, and related businesses in southern Colorado.
