Product Overview : 

Anodes provide cathodic protection in varying marine environments such as salt water, freshwater, and brackish water. Our sacrificial anodes conform to the highest MIL-Spec standards and come in a variety of shapes and sizes. Depending on the type of metal and water we offer zinc, aluminum, and magnesium galvanic anodes for all of your underwater cathodic protection needs

Protect your boat stern in salt water with a bolt-on sacrificial zinc anode. Anode will corrode instead of the equipment. This way, the anode will not disturb the operation of the equipment while preventing electrolytic corrosion.

A full-range of commercial bolt-on zinc anodes for small to large commercial vessels and underwater metal structures. Zinc Bolt on Anodes  STN 800131 for use in the marine environment and manufactured to the US military specification 18001K . Anodes are available in many sizes and shapes.

Zinc Anodes are designed for the protection of various types of vessels such as ships, barges and tankers. Bolt-On Zinc Anode for Stern STN-800131 protect metal parts of Stern from galvanic corrosion.


The anode must be in direct contact with the metal it protects and never paint around an anode or the anode itself.

When Should Anodes Be Replaced ?

Anodes deterioration rate may fluctuate according to the mooring area, water salinity, PH and temperature, potential electrical failure on board, and of course, the quality of the anodes themselves.

A good benchmark for replacement is when the anode is 70-80 % dissolved. We recommend to replace anodes every year when doing the boat antifouling/launching. In all cases, anodes deterioration should always be watched carefully together with the condition of the metal parts they protect.

On the opposite, anodes may dissolve quickly if they are bad quality or if there is an electrical failure on.
