Summary of Zinc Anode 620 The is a specialized sacrificial galvanic anode designed for cathodic protection, primarily used to prevent corrosion of buried or submerged metal structures. 🛠️ Key Technical Specifications

Inspect anodes during scheduled dry-docking or dive surveys.

Zinc anodes should be stored in a dry, clean warehouse to prevent premature consumption due to humidity. They should not be stored directly on concrete without pallets, as moisture wicking can cause surface corrosion that may reduce initial efficiency.
