About Our Zinc Anode Range

Zinc anodes are the industry standard for sacrificial cathodic protection in seawater environments. By corroding preferentially in place of the protected metal, they extend the service life of ship hulls, ballast tanks, jetty piles, heat exchangers, and underwater fixtures — preventing costly galvanic corrosion of the parent structure.

Our zinc anode range is supplied as ZINCALLOY grade, manufactured to recognised marine specifications and complete with embedded mild-steel inserts or M-size fixing bolts as appropriate. From compact 50 mm washer anodes for bolted fittings to heavy 40 kg welded tank anodes, every variant ships ready for direct installation. Custom lengths and configurations are available on request.
