Zinc Ribbon Anode
High-efficiency, continuous wire core zinc ribbon anodes providing flexible cathodic protection and AC mitigation for low-resistivity soils and brines.
What Are Zinc Ribbon Anodes?
Zinc Ribbon Anodes are flexible, continuous zinc strips featuring an internal steel wire core. Because of their unique shape and flexibility, they can be easily unrolled and installed along any length of cathode, making them ideal for pipeline protection, AC mitigation, and grounding.
Galvanic Operation & Safety
Zinc anodes create a reliable galvanic cell with steel structures, functioning effectively in highly conductive electrolytes. Engineered specifically for low-resistivity environments below 1000 ohm-cm, they corrode sacrificially to prevent rust. As a naturally non-sparking metal, zinc provides an exceptionally safe solution for hazardous industrial applications.
