Due to the self-sacrificing characteristics of zinc alloy, the Zinc Anode Collars are used as galvanic anodes for Cathodic Protection of metal structures in brackish and saltwater environments, providing low cost protection against corrosion.

Cor-Collar Zinc Anode Collars have been designed to provide maximum performance and reliability, offering protective DC current for Cathodic Protection purposes. The Zinc Anode Collars are manufactured to meet ASTM B 418 (latest edition) strict standards of chemistry, production control, testing and certification.

Cor-Collar Zinc Anode Collars can be purchased in a variety of shapes, sizes and weights. Stainless steel hardware is used.

Ideal applications of Cor-Collars include:

• Heat exchangers;
• Vessels;
• Ballast Tanks;
• Fire Hhydrants;
• Service boxes;
• Copper water services.
