Zinc sacrificial anode GSC SuperAnode

for reinforced concrete

Galvanic Anodes for cathodic protection of steel in concrete The Galvanic Anode protection systems utilize sacrificial anodes that naturally generate an electrical current to mitigate corrosion of the reinforcing steel. Zinc has a lower (more negative) potential than steel, so the Galvanic Anode provides the current to inhibit the corrosion of steel in concrete. Galvanic cathodic protection systems, which use sacrificial anodes, have recognized advantages of simplicity and reliability, and have recently become available as a viable alternative to ICCP. Unlike ICCP, galvanic CP systems require no extensive wiring or conduit, and no power supplies. Their inherent simplicity greatly reduces the need for ongoing monitoring and maintenance. In concrete structures, zinc anodes are typically used both for maintenance and new structures. A wide range of zinc anodes specifically developed for concrete applications are available.
