Donohoo Steel Treating has grown out of a rich history.

As a 14-year old in the 1920s, Gus Donohoo began working with metals, just as his blacksmith father, uncles, grandfather and great-grandfather had done before him. During his summers off school, Gus worked with the former Velie Automobile Co. in Moline.

In 1931, the Velie firm went out of business, prompting Gus and his father to move to the Cedar Rapids, Iowa area and operate a captive heat treat department for a large company. With the dream of starting their own company and returning to the Quad Cities area, they purchased the land and constructed a new building at the current location, opening Donohoo Steel Treating Co. in 1946. For the next 20 years, they installed the latest equipment and continued to build a solid reputation in the heat treating industry.

In 1965, Gus’s son, Bill Donohoo, joined his father’s business, becoming Vice President in charge of production. After Gus Donohoo passed away in 1982, Bill Donohoo took over as President.

In 1989 and fresh out of high school, Chris Zubroski joined the company, working in maintenance and production. Recognizing Chris’ dedication, knowledge and skill, Bill continued to promote Chris through the ranks until 2007 when Chris became Operations Manager.

Bill Donohoo retired at the end of 2013.

In 2014, Chris Zubroski purchased the company from Bill Donohoo.  Today, Donohoo Steel Treating, a division of Iowa Steel Treating, Inc., operates as a recognized leader in the heat treating industry. Continual improvements in technological advances and processes help the business stay competitive and control costs. The Company’s values remain grounded in those established by its predecessors – supply quality services on a timely basis at competitive prices.
