Aluminium Anodes

Rig/Platform/Harbour/Jetty/Frame

Aberdeen Foundries 'DEFENDER' brand Aluminium marine anodes come in the widest range of sizes and are for use in all types of applications for protection of harbours and jetties, platforms, ships hulls, tanks, drill rigs and pipelines. Aluminium is popular as base metal prices and specific properties of aluminium-zinc-indium based anodes make them the best value for money in terms of the protection offered per kg of anode weight.
