Contractors Steel Co. is a service center with five Midwestern U.S. locations and more than 100,000 tons of carbon and structural steels in inventory. The business was founded in 1960 by Don Simon. 

"Contractors Steel is a company where entrepreneurialism and family values took hold decades ago – a model we are replicating with Union Partners today. We are honored to welcome Contractors to the family and humbled that Don Simon, who is greatly admired in the industry, has chosen us to carry on his legacy," said Union Partners co-founders Chris Hutter and Paul Douglass in a statement.  

The firm said the strategic acquisition extends its geographical reach and expands the product offerings of its portfolio. Union Partners’ portfolio companies include Maksteel, Mapes & Sprowl, Lee Steel, Chicago Steel, Berg Steel, Opus Metals and its greenfield development on the Big River Steel campus.

The firm also said it has named Contractors chief operating officer Marc Bokas as chief executive. 

"Union Partners' acquisition of Contractors Steel opens a whole new range of opportunities for our employees and customers,” Bokas said. 

“Combining the best practices and policies of Contractors Steel Company along with those of the Union Partners' family of companies, we shall strive to produce an optimum operating entity that will meet or exceed all industry standards and expectations.”
