Description:
Zinc anode has been developed by CORROCO for more than 20 years, it is a casted or extruded anode, melted, casted and extruded by high pure Zinc or Zn-Al-Cd alloy. With high capacity, current efficiency and high machine performance, Zinc anodes are widely used in cathodic protection of tank bottom, pipeline, and water pipe in soil environment.
