Featuring Mil Spec zinc anodes, MIL-DTL-18001 (Type ZHS, ZHB, ZSS, ZEP, and more) and ultra-pure anodes to ASTM B418 Type II.

Belmont Metals has been a leading manufacturer of Zinc Cathodic Anodes. Cathodic Protection, also referred to as a sacrificial cathode, is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects protected metal to a more easily corroded “ sacrificial metal “ to act as the anode. The sacrificial metal then corrodes instead of the protected metal.

Applications:

Zinc Cathodic Anodes are used to protect a wide range of metallic structures in various environments. Common applications are, steel water or fuel pipelines and storage tanks such as home water heaters , steel pier piles as well as boat, ship and submarine hulls along with seawater sides of condensers and other heat exchangers. All Zinc Anodes are available for Government use with full certification as well as for Industrial use.

Forms:

Type ZHS, ZHC, ZSS, ZEP ( STYLE A, B & C ) , ZTS, ZRN with shapes outlined in specification MIL-A-18001. Belmont Metals also offers custom formula, shapes, sizes & straps. Also available are Zinc Replacement Elements and Brass Plugs ( Type ZDT & ZDM ) along with Zinc Pencil Anodes and Brass Plugs.
