Baltimore Galvanizing.
They recently (2021) did 300 feet of 3/8 chain for me for $265, their minimum job charge. I should have included my anchor too, but I didn't bring it.

Being the only game in town leads to rapacious pricing. And it is ironic, for we are in a marina that is right next to a giant zinc smelting works!

heh jim
as matter of interest, who did you go to for the chain ? standard or HT ?
having just replaced ours, we are not in the chain market for a few years but always interested to see what the experts are doing
btw, was in bundy recently and talking to a chap who has just gotten his chain re-galvanised there. still super cheap and super good job. unfortunately this does not help when you are in tassie...
cheers,

Re: Expected Chain Lifespan
Duplex S/S chain 10 mm standard links was quoted from Qld @ ~ AUD 100/meter...and we wanted 80 m. Did not get it. Salesman said people buy it for brand new boats they plan on keeping "a while".
Cheers,
Ann

Chris, the vendor is Muir in Coomera. Good price for the chain but 370 bucks and a week+ shipping (promised, not yet delivered). And not PWM chain, either, for Muir says PWM is now made in China and they no longer choose to represent them. I'm a little leery, but Muir has supplied all my chain needs for the past 15+ years and I'm willing to take their word that the quality has been adequate on their new stuff. Not many choices in these parts!
We have never seen the need for high test chain, so this is grade L, which is G30 (or better). It would take really extraordinary circumstances for I-2 to break that chain (10 mm).
Bundy would have been a good move for us, but we ain't leaving Tassie just yet... and summer is just around the corner (that said, yesterday the high was 12 dec and we had gusts over 50 kts yet again, with heavy rain at times and snow on Mt Welly). Heater running 10+ hours a day...

PWB not PWM.
I wonder who's chain they use now?
I still have an as yet unused 80m of Oz made PWB in the locker but after that?????
Thinking Hampidjan Commercial Fishing Equipment | Dyneema Rope
They recently made an announcement that they are getting in grade L from Force chain in Turkey

Wow Jim that is expensive!
Just had my Chain regalvanized here in Luzon and it cost me Php 45.6/kg .. = AUD 1.26/kg
Same industrial place I have been using every few years and they do a good job in degalvanizing in-house and using a large vibrating tank.
So was able to inspect after blasting and acid bath before deciding to regalvanize
They screwed up this time as they forgot to turn on the vibrator on the weekend shift.
When i returned to pick it up, it was all fused together. The QC supervisor was very embarrassed and they redid it perfectly!
I am a bit oversized at 13mm chain and tend to anchor deep with lots of scope, so Titan chain has lasted well as I regularly end for end, take off the last 3 links before shackle and keep well galvanized .
Thought about renewing this time around, but the Chinease DIN rated chain available via Broadwater has had a reputation of very poor galvanizing on boats who've bought it.
So decided to stay with what I know and has been working for 20 years.

Re: Expected Chain Lifespan
while we are all talking about chain lifespan, one thing i do pretty much all the time while in port is leave the deck hatch to the anchor locker open. good ventilation helps prevent rust

I know the lifespan we get from cheap Chinese chain with thin galvanizing (about 3 years) and its cost. I know the cost of USA chain… but I don’t have a good number for the lifespan of the USA chain to compare the prices on a Dollar/year basis.
I strongly suspect the USA chain will prove to be the long term bargain, but data would be nice!

What makes you think usa chain is high quality? What little steel is made in usa nowadays isnt wasted on anchor chain i can assure you.
Its all china steel or worse canadian .

Hi Bill,
I recently had my chain and anchor galvanized at VS Taunton Galvanizing in Taunton, MA. They were glad to do it, though it's a small job for them, and it was far less than the cost of new chain. That was before the current price crisis on everything, though.
That Acco chain had been full-time anchored for five+ years and was still in pretty good shape. I have a grating in my chain locker so the back end doesn't sit in water, and most of the chain sits in a pile further back where wet chain won't stack on top of it. I hate it when the back ends of chain freeze into a lump in the bottom of the locker.

We had ours re-coated with Armor Galvanize in West Michigan near Holland. 4 years in Great Lakes and three in the Caribbean.
We have greatly reduced zinc loss by making sure the chain is electrically isolated from the boat. Consider that the thin zinc on your chain should not be the sacrificial anode protecting the boat. For us, that means windlass breaker open and a big switch to open the neutral wire.
Rocky bottom is death to a chain. If you hear it dragging around, MOVE!

Testing has proven that a lot of China chain is actually higher grade than spec, so likely better than US, OZ or EU chain
China steel, made from high quality Oz red dirt and black dirt
Quote:
A total of 13 chain samples was tested destructively using a 50 ton Denison tensile tester. The samples included several made in Europe but the majority were from Chinese factories. Four were Grade 40, nine were Grade 30. Every sample achieved the required strength for its grade but it was noticeable that every Chinese Grade 30 chain, with one exception, delivered the strength of a Grade 40. The result suggests that steels used for Grade 40, typical of constructional steels, are more readily obtainable in China than the lower carbon steel used for Grade 30

I think the problem has been more to do with the original galvanizing failing within the first year

Indeed! In the yachting usage, chain failure (ie breaking) is extremely rare. Rapid galvo failure is unfortunately fairly common... and in chain from various origins.
