Stand-Off Aluminum Anode with Goal Post Tubular Insert Protruding from Back Face

Aluminum anode is a popular choice for off-shore cathodic protection due to its light weight, simplicity of installation and adaptability to cast into a variety of sizes. As the stand-off anode protrudes from the surface installed, so the anode material is not in direct contact with the surface to be protected. Thus, the stand-off anode is better utilized over their lifetime — its anode utilization factor can reach up to 85 to 90%.
