Plating Technology’s experience, commitment to quality, and investment in the latest equipment has earned us an industry-wide reputation for providing high quality finishes at very competitive prices. Our tin-zinc plating services, recommended for use on fasteners and other electrically conductive components used in corrosive environments, exhibits such high corrosion resistance that it routinely surpasses 1500 hours when subjected to ASTM B-117 salt spray testing.

Our fully automated barrel plating equipment applies a uniform finish. Environmentally friendly, the process uses a trivalent chromium passivate to form a corrosion resistant, electrically conductive, and weatherproof coating that withstands even the harshest, sulfur-enhanced environments. The finish also exhibits excellent lubricity, ductility, and solderability, even after months of storage.

Able to handle quantities from prototypes to large scale production runs with 1–5 day lead times, our tin-zinc plating services are suitable for parts used in transportation, construction, mining, and marine applications, and meets the requirements for many auto manufacturer specifications. Our ISO 9001 and ISO 17025 certified facilities are equipped to handle the needs of the most demanding applications.
