ZERO Manufacturing, Inc.'s capabilities and many of its products as manufactured currently, had their beginnings in a small metal shop in southern California named Zierold Metal Corporation. Many people had difficulty pronouncing the name Zierold, so in 1952, after being purchased by Jack B. Gilbert, the name was changed to ZERO. Known as ZERO Corporation, the company grew to include facilities and operations in several locations around the United States.
In 1991, ZERO Corporation expanded, relocating its main operations center in North Salt Lake, Utah. In 1998, ZERO transferred its plastic case manufacturing capability from Monson, MA to the North Salt Lake facility. By 2002, the assets and capabilities of the Utah operation, along with the rights to use the ZERO name were acquired by ZERO Manufacturing, Inc.
Today, the company currently operates under the name of ZERO Corporation, with ZERO Manufacturing, Inc. as a wholly owned subsidiary. As the leading manufacturer of both aluminum and plastic enclosures, ZERO exceeds customer's expectations by offering unparalleled protection and creative custom designed manufacturing solutions for any type of case, enclosure, or standardized product.
