Galvanized Coatings Test
Chain makers must find sweet spot between thickness and adhesion.
Corrosion attacks anchor chain long before it has reached the end of its useful life, and corrosion begins as soon the galvanized coating fails. Re-galvanizing can breathe new life into old chain, but it is not so simple or affordable as it used to be. As we saw in our most recent report on chain (see Practical Sailor June 2014 online), some of the high-tensile grades require specialized skills to galvanize, and others canít be galvanized at all. Even if galvanizing is an option, removing rusty old chain from the boat and delivering it to the galvanizer can make moving pianos seem like a cinch.
