Cerrowire has a long and successful history in the copper wire and cable industry. The company was originally established as Circle Flexible Conduit Co., Inc. in the 1920s, manufacturing and selling armored cable and flexible steel conduit. Over the years, they expanded their product line to include various types of copper wire and cable.

In 1955, Cerro de Pasco Corp. acquired the company, leading to the development of Cerro Wire & Cable Company. In 1976, Cerro Wire & Cable became a member of The Marmon Group, a global industrial organization.
