What Professional Plating does

Professional Plating Inc. (PPI) is a privately held metal surface finishing company founded in 1979 and headquartered in Brillion, Wisconsin. From a 200,000-square-foot facility employing more than 200 people, the company operates a one-stop-shop model that consolidates barrel zinc plating, rack zinc plating, acrylic e-coating, epoxy e-coating, and powder coating under a single roof, supported by value-added services including sand and shot blasting, assembly, packaging, and in-house trucking. Ownership rests with the Endries family, and customers include OEMs and production machining operations serving the automotive, industrial, recreational, agricultural, and aerospace sectors across the Midwest.

The technical platform rests on a 10-stage pre-treatment process using iron phosphate and a Pro-Seal non-chrome sealant for powder coating operations, along with proprietary service bundles Pro-Advantage (combined e-coat primer plus powder coat) and Pro-Dura Clear. The company has invested more than $30 million over 15 years in facility upgrades, automation, and IoT-enabled quality control, with $4 million committed to a second zinc barrel line in late 2023 and $5.3 million committed to a new Epoxy E-coat line commissioned in July 2024. Quality systems are anchored by ISO 9001:2015 certification held continuously since 2001, recognized by an 11-time Products Finishing Top Shops Benchmarking Survey award and Top Metal Plating Service of 2025 by Manufacturing Outlook.

Revenue is generated on a quote-based, transaction-fee pricing model with multi-year contracts, customized per part specification, volume, and finish requirements. Approximately 35% of finished parts ship directly from PPI to customers' end users via the company's own trucking fleet, with daily delivery to the greater Milwaukee metropolitan area and broader service to Appleton, Green Bay, Manitowoc, and Madison. The company self-describes as a 'one-stop-shop' receiving parts from manufacturers, applying specified finishes, and either returning parts to customers or drop-shipping to downstream recipients.
