Re-Galvanizing Shops Near NY/NJ/CT?

Does anyone know of any places to get my 45' CQR and 200' of chain re-galvanized around the NY/NJ/CT area?

I have been looking at listings online, asking around and asking at West Marine. Nobody knows.

Thanks.

Sean I brought mine to a place up near Hartford which did a lot of wok for the state. I was very unhappy with the results... and ended up buying new chain... the anchor was so so. My CQR flukes are now starting to show rust (again) so I think it's time to retire this one as a spare and replace it. I cannot recommend re galvanizing. Good luck.

Thanks for the link, Gord. I gave them a shout to see what their rates are and if they so smaller projects like this.

Jef, we could probably go in on a galvanizing, since from what I read, they typically start with a fixed fee and add fees by lbs of metal. I'll PM you.

Galvanising a chain.

Galvanising a chain is a good practice as it will be cheaper than buying a new one.. B U T :

Be shure that you chain in in good shape, no "elongated" links, and check that the diameter of the links is not reduced (by rust) to more than 1/10e..

Next but most important point, check that your galvanisation company is using a "vibrating drum" when the chain is lifted out the melted zinc bath.. Vibrations during the cooling process is a MUST- otherwise several to most of the links could be welded together, and the chain will be galvanised.. but useless..

You can still break the weld by a hamer, but then there is very good chance that you will also at the same time remove the galvanisation..

“Corrosion Management” magazine*: Industrial Galvanizers
has some excellent galvanizing articles, and the “Ingal Specifiers Manual”
INDUSTRIAL GALVANIZERS - 01 SPECIFIERS MANUAL

Alain's post gets me thinking: How do you measure chain wear?

There are spots (such as on the anchor shackle) that have a distinct wear area from rubbing as the chain moved around with the anchor in the ground all last summer. These areas show spots (tiny spots) of rust. Other parts of the chain and anchor are merely colored darket than the normal galvanized color, so I assume the zinc is gone. Also, there are tiny spots (size of a pencil eraser) on the far points of the flukes that have spots of rust on the anchor itself. Any suggestions on this general amount of wear?

Welded steel chain should be replaced when any wear exceeds 7 percent of the original section dimension.
