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.

Pier / Piling Anodes Gallery
Diver installed
Dual clamp on anodes installed on the shallow portions of the structure.
Replace depleted anodes
Dual clamp-on anodes are designed to replace platform anodes on structural members.
Supplemental current
On deeper structures, it is sometimes necessary to use a combination of Retropods on the sea floor and Dual clamp-ons near the surface.
