Frequently Asked Questions
What is a zinc anode and why is it needed?
Zinc anodes are sacrificial metals attached to marine structures to prevent galvanic corrosion. They corrode instead of the metal parts they protect, forming an essential part of a vessel's cathodic protection system.
How often should zinc anodes be replaced?
Inspection intervals depend on water salinity, temperature, and vessel usage. As a rule, check every 6 months and replace when approximately 50-75% of the anode has been consumed.
How do I select the correct zinc anode size?
Choose an anode with a surface area proportional to the amount of metal to be protected. Larger propellers, rudders, and shafts require larger anodes. Consult a marine engineer or refer to vessel specifications for exact sizing.
Can zinc anodes be used in freshwater or saltwater?
Zinc anodes are most effective in saltwater. For freshwater or brackish environments, aluminum or magnesium anodes may be more suitable. However, zinc remains the preferred choice for ocean-going vessels and offshore equipment.
