Pier / piling anodes

Sacrificial aluminum anodes for piers and pilings

Docks1296PX.jpg

Deepwater's aluminum pier and piling anodes provide cathodic protection for any type of jetty structure.

Deepwater's aluminum galvanic anodes for piers and pilings are cast in one of two premium aluminum alloys (Deep7 and Deep10) for optimal performance under any conditions. Anodes are manufactured in several "standard" sizes shown below. In addition to these, Deepwater can cast anodes for piers, jetties, or any other piling to the exact specifications required. Please contact us for advice on optimizing an anode to suit your specific requirements.
