Zinc Barrel Plating of Hot-Rolled Steel Towing Components

At Signal Plating, Inc. we utilized our barrel plating line to zinc plate a variety of components for a customer in the tow and recovery industry. Since these tow hooks, cluster hooks, control handles, and control levers, all fabricated from hot rolled steel, would be used in outdoor applications and subject to varying temperature and weather conditions, we recommended a .0003″ zinc plating with a supplemental trivalent chromium treatment. This 2-part process would give the parts the durability and corrosion protection required to provide a long and reliable service life. Our large plating barrels allowed us to process a high volume of parts in a short amount of time, and our fully computer controlled process guaranteed reliable results that passed both visual and thickness inspections.
