Our Zinc Anodes set the standard when it comes to cathodic protection. They meet all standards set forth by Mil-Spec A-18001K, Mil-Spec A-18001A, and Mil-Spec A-18001.
Maintenance is an important part of owning a boat lift and, depending on your environment, your sacrificial anodes may need to be checked and replaced fairly often. Anodes (also referred to as zincs) protect the metal parts of your lift from galvanic corrosion, which occurs when any two dissimilar metals are physically or electrically connected and immersed in water. These conditions create a circuit (just like a battery) with current flowing from one of the metals to the other. A sacrificial anode, added to the circuit, is designed to provide the electrons to the circuit instead of the other metals, preventing galvanic corrosion of important parts. As a result, checking and replacing anodes periodically is a critical part of any maintenance schedule.
