Zinc Casting Rounds – Marine Sacrificial Anodes (IMPA 673401)

Zinc casting rounds are durable, high-purity sacrificial anodes designed to protect critical metallic components on commercial and recreational vessels. These marine-grade anodes prevent electrolytic corrosion by creating a galvanic cell that sacrifices zinc instead of your hull, rudder, or ballast tank steel. Sourced to meet strict marine industry standards, each round delivers dependable cathodic protection even in high-salinity conditions.

Ideal for shipyards, fleet maintenance, and offshore structures, these zinc anodes are available in a range of standard diameters and lengths to suit various mounting configurations. They can be welded, bolted, or clamped to hull plates, sea-chests, heat exchangers, and pipework. With consistent alloy quality and precise manufacturing, our zinc casting rounds ensure extended service life and reduced dry-dock maintenance costs.

Stocked under IMPA 673401 and supplied in safe, easy-to-store packaging, these rounds are ready for global delivery to any ship repair facility or chandler. All sizes are manufactured to deliver uniform current output and excellent performance in marine environments.
