Zinc Anodes for Cathodic Protection Applications
RELI SLEEVE Zinc Anodes are sacrificial anodes manufactured for cathodic protection of steel structures in marine and seawater environments. Zinc anodes provide galvanic protection by acting as the sacrificial material and helping protect connected steel structures from corrosion.
ZINC SACRIFICIAL ANODES
Zinc Anodes Product Introduction
Zinc anodes are sacrificial anodes used in cathodic protection systems to reduce corrosion of submerged steel structures. Zinc acts as the sacrificial metal and supplies protective current to the connected steel surface.
Zinc sacrificial anodes are widely used in marine applications including ship hulls, seawater structures and other submerged steel assets where galvanic cathodic protection is required.
RELI SLEEVE manufactures zinc anodes in application-specific configurations according to approved engineering drawings, cathodic protection requirements, applicable standards and customer specifications.
