PriceWalgren History

In 2015, Walgren joined Price-Koch Industries as a division of George Koch Sons. The new entity, which has global reach across a broad spectrum of production scale finishing technologies, is today known as PriceWalgren.

In 2016, PriceWalgren expanded into an 85,000 sq. ft. world headquarters campus in Grand Rapids, MI, just 4 miles from Gerald R. Ford International Airport. This move gave PriceWalgren’s legendary base of repeat customers access to an expansive range of technological, administrative and financial resources.

Our long history of service to the industry has made us a preeminent designer-manufacturer of large scale anodizing, plating, phosphating, autodeposition, and electrocoating systems.


Leadership has been the heart of our success story. Several management team members remained in place following the acquisition by George Koch Sons. The professionals who lead PriceWalgren today each have a powerful commitment to the industry that is decades-long. Collectively and individually, we have a wide range of experience in engineering, design, manufacturing, waste treatment, system installation, and the successful management of complex projects.
