Keystone Koating Turns 40: Certifications Drive Industrial Powder Coating

Keystone Koating has served manufacturers for 40 years. The company runs two facilities in Central Pennsylvania. It holds ISO 9001:2015 certification, PCI 3000 Custom Coater certification, and AAMA 2604/2605-compliant applicator status. Each requires ongoing adherence to production and quality standards, not a one-time check.

Operations managers and production engineers evaluating industrial powder coaters look for credentials tied to repeatable processes. Keystone's portfolio also includes IFS registration, which reflects consistent investment in process accountability across both plants. The company serves HVAC producers, agricultural equipment fabricators, and automotive component makers.

High-volume powder coating demands a process that moves large quantities without variability. Keystone's eight-stage pretreatment system runs from blasting through surface preparation, quality testing, and final shipment. The company uses powders from top manufacturers. "We continually optimize our process to ensure the best quality finish every time," the company said.

The result is a coating with resistance to chipping and strong adhesion. Epoxy, polyester, and fluoropolymer options offer flexibility. Turnaround times help production teams maintain schedules. Keystone Koating is part of the Paul B. Zimmerman family of companies.
