Overview
Zinc anodes offer a stable, moderate driving potential and are widely used for protecting ships, harbors and inland structures in low-resistivity environments. As a proven sacrificial anode, zinc is especially effective on steel in seawater and brackish water.
Selection Criteria
Choosing between magnesium anode, aluminum anode and zinc depends on soil or water resistivity and the required current output. Zinc performs best where resistivity is below 1500 ohm-cm and temperature stays under 50 degrees Celsius.

Related Solutions
When structures need active control, combine zinc anodes with an ICCP system. For land-based civil works we also supply FRP rebar and carbon fiber tube that resist chloride attack in aggressive soils.
