HISTORY
1948
THE BEGINNING
Arnette Pattern Company, located in Granite City, Illinois, first opened its doors under the ownership of Dale Arnette. At this time, Bill Zimmer was 18 years old and just beginning his first year of apprenticeship as a pattern maker.
1974
Bill was joined by his son Gary Zimmer, as he began his apprenticeship in the craft.
1978
Bill and Gary assumed ownership of Arnette Pattern Company, and they were joined by Bill’s other sons, David Zimmer and Paul Zimmer, also as apprentice pattern makers.
1982
Bill and Gary assumed ownership of Arnette Pattern Company, and they were joined by Bill’s other sons, David Zimmer and Paul Zimmer, also as apprentice pattern makers.
1994
Bill retired from his ownership responsibilities but remained full-time for another 20 years. At this time David and Paul joined Gary in the ownership and operation of Arnette-Midwest.
2002
Paul Waltenberger, Paul Zimmer’s brother-in-law, joined the Arnette-Midwest team after gaining experience in the steel industry at Lapham-Hickey Steel. Also, during this time frame, many experienced employees were hired which added to the Fabrication, Machining, and Pattern Making Divisions.
2004
Paul Waltenberger assumed part-ownership and with his valuable experience in the steel industry, he helped propel the growth of our steel fabrication department.
2009
ARNETTE-MIDWEST
Arnette-Midwest’s commitment to continual improvement in customer service resulted in the construction of a new 30,000 square foot facility designed to serve as corporate headquarters, as well as the main location for Arnette-Midwest’s industrial pattern making, mold making, and machining departments.
2012
THE EXPANSION
In 2011 we began expansion of our main facility to accommodate growth in our machine building and machine re-building market segments. This 25,000 square foot addition provided space for numerous new machining centers, an updated fabrication area, and an expanded design/engineering department. Completed in early Spring, 2012, the extra capacity has also resulted in a 50% increase in the company’s overall workforce.
2014
THE EXPANSION CONT.
In April we leased an adjacent 12,500 square foot building to provide additional capacity for our growing machine building and machine re-building business sectors. We teamed up with US Steel, Granite City Works, to revamp the entire Caster Line at the plant.
2017
With Gary Zimmer’s retirement, Paul Zimmer and Paul Waltenberger acquired full ownership of Arnette-Midwest and assumed the President and Vice President roles respectively.
2022
FABRICATION
In 2022 we began another expansion of our fabrication facility to accommodate growth in the power and energy market. This 12,000 square foot addition allowed us to hire several more employees to service this growing segment.
