Cathodic Protection

« Back to Glossary Index

Cathodic protection (CP) can be defined as e.g. “electrochemical protection by decreasing the corrosion potential to a level at which the corrosion rate of the metal is significantly reduced” (ISO 8044) or “a technique to reduce corrosion of a metal surface by making that surface the cathode of an electrochemical cell” (NACE RP0176). The process of suppressing the corrosion potential to a more negative potential is referred to as cathodic polarization. Cathodic protection, stops and delays the progress of corrosion on both new and older metal structures.

This means: Prolonging your steel structures life expectancy and durability. Thereby decreasing maintenance costs. Steel structures in soil, water and concrete are effectively protected by cathodic protection.
