A Zinc Anode for Hull is a sacrificial (galvanic) anode specifically designed for the cathodic protection (CP) of ship hulls and submerged steel structures in seawater environments. The zinc anode protects the hull by corroding preferentially, thereby preventing rust and extending the vessel’s service life.
