An Aluminum Anode for Harbor and Marine Engineering Facilities is a sacrificial anode used in cathodic protection (CP) systems to protect steel structures exposed to seawater. The aluminum anode corrodes preferentially, providing protective current to structures such as piers, jetties, offshore platforms, and subsea installations.
