Galvanizing Chain

Does anyone in the Toronto - GTA - Durham - York region area know a place where I can take my anchor chain to be stripped and re-galvanized?

If memory serves me; Earl Hinz who wrote the seminal book on anchoring and mooring Amazon.com: The Complete Book of Anchoring and Mooring (9780870335396): Earl R. Hinz: Books
cautions that the process of galvanizing chain reduces its strength by 10% and that a chain should only be re-galvanized twice.

Does that mean it loses 10% each time?

David-That is my recollection as I do not have the book at my fingertips. The process of galvanizing is pretty abusive to the substrate and includes sand blasting; acid dipping and the final high temp bath in zinc. All, according to Hinz, degrades the chain enough for his recommendation.

Wouldn't think chain is sand blasted each re-galv unless it's in a pretty rough state.

The strength lose could be anything from 'a little' to 'she's buggered chuck it and start again'. All depends on the skill and care of the person doing the re-galv.

Some comments from some who would have a reasonable idea -

Re: Galvanizing Chain

Wherever you take it make sure that they use a centrifuge type process for galvanizing the chain. The regular galvanizing process will leave way too much material on the chain and it will not work properly on your windlass. I was told this by two galvanizing places who turned down my job, one referred me to the only galvanizer in the Seattle area that can do marine chain.

Re: Galvanizing Chain

I did a refit last summer on the east coast. Called all over the place and could not find anyone doing chain any longer. Anchors, yes. Chain, no. Some indicated that they used to do it but not anymore.

Good luck with it!
