Background on Zinc Anodes
An industry standard for many years, zinc galvanic anodes are utilized to protect a variety of steel structures from the affects of corrosion. Historically, zinc anodes have been designed for use in salt or brackish water applications. Due to the U.S. Navy’s widespread use of zinc in the early 1950’s, a specification (MIL-A-18001) was developed for galvanic zinc anodes in seawater. This zinc specification, with revisions, is still in use today and is a standard in the corrosion control industry.
Soil Anodes
Farwest provides sacrificial zinc anodes made to ASTM-B-418 Type II specifications for corrosion protection of steel structures in soil. These anodes are made from 99.99% pure Special High Grade Zinc and are ideally suited for galvanic protection of metal in soil.
