What Keystone Koating does

Keystone Koating is a privately held B2B industrial powder coating contractor founded in 1986 by Nelson Zimmerman and headquartered in Lititz, Pennsylvania, operating as a subsidiary of Paul B. Zimmerman, Inc. The company applies electrostatic-applied dry pigment and resin finishes to metal components, using a proprietary 8-stage pretreatment system with aluminum-specific seal chemistry and an internal Quality Assurance Lab equipped with a Salt Fog Cabinet for ASTM-standardized corrosion, adhesion, and solvent-resistance testing. It holds AAMA 2604 and AAMA 2605 certifications (the highest tier of architectural powder coating performance), ISO 9001, and Certified Applicator status with Axalta, IFS, and the Powder Coating Institute, plus a 2015 Products Finishing Top Shop Award.

The company operates two production facilities — Plant 1 in Lititz (main conveyor lines, batch units, upgraded topcoat and small-run spray booths, QA Lab) and Plant 3 in Mifflintown (batch coating units, opened 2006 adjacent to major customer DuMor Site Furnishings) — and announced the acquisition of a third 177,000-square-foot facility in Lebanon, PA in June 2026 for integration with sister company PBZ Manufacturing. Service breadth spans surface preparation (steel grit and aluminum oxide abrasive blasting), the proprietary pretreatment process, electrostatic coating, curing, color matching and texturing, custom packaging, and in-house trucking.

Go-to-market is sales-led and B2B-only since 2014, targeting industrial manufacturers and OEM component providers across agriculture, commercial automotive, commercial furniture (e.g., Knoll), architecture, municipalities (e.g., Spring City Electrical street lamps), HVAC/sheet metal/data center, and site furnishings. Pricing is fully quote-based with 24-hour turnaround; no public price list. Distribution is regional (Lancaster County / central Pennsylvania) via direct field sales, inside sales, and trade show engagement. Customer concentration risk is anchored by DuMor Site Furnishings (cited as one of the largest clients and the geographic anchor of the Mifflintown plant), partially diversified across a multi-vertical named customer base that includes Knoll, Spring City Electrical, Swing Kingdom, and Main Line Helicopter.
