"We are excited to broaden our reach to new client markets with the quality services and products that National Metalwares has built," said Union Partners co-founders Chris Hutter and Paul Douglass in a statement.

"The combination of Union Partners and National Metalwares creates an exciting opportunity for both companies, our customers and for our talented team members. The resulting synergies will allow us to bring the best solutions to the industry," they said. 

Based in Aurora, Ill., National Metalwares is a maker of OEM steel tubing, tubular components and welded assemblies. It also produces components for residential, office, and education furniture; consumer lawn and garden equipment; and other outdoor powered equipment.

Union Partners said the acquisition complements its existing service centers and processors and provides vertical integration supply chain opportunities across its portfolio.
