Sacrificial anodes

Aluminum and zinc anodes for cathodic protection of offshore and marine assets

Deepwater provides zinc and aluminum anodes for offshore cathodic protection. We always abide by the strictest chemical composition standards published by NACE. All anodes that Deepwater provides in our proprietary systems are manufactured at an ISO 9000-certified foundry, pre-screened and approved by our engineers.
