Our zinc sacrificial anodes are designed for galvanic cathodic protection of steel structures exposed to seawater and other electrolytic environments.
This zinc anode features a one-sided extended steel core, which provides a practical connection point for electrical bonding and mechanical installation. The steel core extends from one end of the zinc anode body and can be adapted to different installation requirements.
Zinc sacrificial anodes are commonly used to protect steel structures by acting as the sacrificial metal in a galvanic cathodic protection system.
