Product Catalog

Zinc cast anodes are recommended for use in soils with resistivities below 1,000 ohm-cm. Because these anodes have a driving voltage that is lower than magnesium, they are most effective on well-coated steel structures which require minimal current output. The packaged anodes are commonly used as grounding cells on electrical motors, panels and conduits and across insulators on pipelines to limit dangerously high voltages. The extruded ribbon anode can be used in buried applications. 

Neither type of zinc anode should be used in extremely alkaline conditions above 9.2pH, acidic below 5pH or high temperatures above 140˚F electrolytes.

Corrpro zinc anodes are available in a variety of weights and dimensions. Zinc ribbon is typically supplied on wood spools.
