Renold Hydro-ServiceŽ chains are treated with a mechanical zinc plating process with additional coatings applied for extra corrosion protection. The corrosion resistance of this coating in many wet, humid, saltwater or other moisture-related applications is far superior to standard nickel or zinc plating.

Unlike some products treated in a similar way for corrosion resistance, Renold Hydro-ServiceŽ chain is hexavalent chrome-free, ensuring that it is safe and also environmentally friendly. This coating can be applied to standard or adapted, BS or ANSI chain.

All components of the Hydro-ServiceŽ chain are treated prior to assembly in order to achieve full coverage and protection to all vital surfaces, not just those visible external surfaces. This helps to improve chain wear life and protect against corrosion-related pin and bushing failures. Unlike nickel or zinc platings, the Hydro-ServiceŽ treatment will not chip or peel. This extremely durable coating will continue to provide exceptional protection where other treatments fail.
