Cathodic Protection Solutions from Sea to Shore

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

Corrosion is the spontaneous chemical reaction of a metal against its surroundings. Particularly, in sea water this chemical reaction proceeds by an electrochemical mechanism involving oxidation of the metal, which results in metal loss. That happens when we have a plate with pitting appearance, at the spots where the coating is not good enough to protect.

The part of the metal surface in the electrochemical mechanism (electron release) is called anodic. The other part of the metal surface where the electron consumption takes place is called cathodic.
