Two is better for you

A Little History

Breaking ground in Mifflintown

Keystone Koating began in 1986 as a way to professionally coat the metal products manufactured by the Paul B. Zimmerman, Inc. family of companies, particularly PBZ LLC’s metal fabrication plant based in Lititz, Pa. As we established a reputation for quality and customer service, outside firms contacted us to powder coat their products. In order to serve our growing list of clients, we added a second location in Mifflintown, PA in 2005. We have continued to grow over the years and pride ourselves in creating mutually beneficial partnerships with our clients.
