Cathodic Protection

advanced divider

At KATRADIS, we deliver total corrosion control. Moving beyond simple product supply, our engineering team provides expert corrosion studies, technical assessments, and custom-tailored proposals to safeguard your assets in the most demanding environments.

Leveraging advanced R&D and eco-friendly Cadmium-Free Alloys (Zinc & Aluminum) developed in collaboration with the National Technical University of Athens, we protect high-value infrastructure across multiple sectors:

  • Shipping & Maritime: High-efficiency protection for ship hulls and ballast tanks.
  • Offshore & Ports: Heavy-duty defense for oil rigs, wind farms, and port structures.
  • Refineries & Industry: Specialized engineering for pipelines and industrial storage tanks.

From initial design and electrochemical study to premium anode delivery, we ensure maximum asset lifespan and full regulatory compliance.

Principle of cathodic protection

Marine corrosion is a natural electrochemical process that leads to severe metal degradation and structural loss when submerged surfaces react with seawater. Where protective coatings are compromised, localized oxidation occurs, creating anodic areas that release electrons and cathodic areas that consume them.

Cathodic protection neutralizes this destructive process by introducing sacrificial anodes manufactured from eco-friendly, cadmium-free zinc or aluminum alloys to the system. By sacrificing themselves, these anodes continuously release electrons, forcing the vessel’s steel structure to act entirely as a protected cathode, thus extending asset lifespan and preserving structural integrity.
