Re: Chain galvanizing

While it can be fun to blame "all the liberal tree huggers" when I called around I found that the galvanizers had enough business already and did not want to mess with small amounts of labor intensive chain.

Re: Chain galvanizing

You might both be saying the same thing. Environmental restrictions may have put the small shops out of business. I'm good with not putting toxic chemicals in the earth or air, but wouldn't be surprised that smaller shop couldn't afford to upgrade to the safety standards. They are often draconian and based upon zero tolerance, not smart science.

I'm not sure if re-galvanizing anchor chain is the way to go. Used chain loses some of it's strength, just by using it. If the galvanizing has come off, perhaps it's lost a bit more, due to corrosion. Unfortunately, chain is a wear item and needs to be replace after a while. I think rinsing the locker down with fresh water helps significantly extend chain life. Eventually, you have to bite the bullet.

Re: Chain galvanizing

I read Fatty Goodlander's book on anchoring recently. He calls it creative anchoring. He has a cycle where his 300' or so of anchor chain is regalvavized. He keeps on using it. He also anchors in the worst conditions that demand a lot from his gear. From his experience I would and plan to have my chain regalvanized. However that will likely not be done in the US.

Re: Chain galvanizing

The river that is our anchorage had a battery factory on it. (Exide. You've probably heard of them. Not a mom & pop operation.) They apparently didn't pay much attention to the environment and closed the factory- without having followed the law too carefully. Swans eating from the sediment developed lead poisoning and died. Cygnets had birth defects and died. Geese, ducks, egrets and other shorebirds suffered as well. Shellfish and crabs were unsafe to eat. Sailors were advised not to even swim in the harbor. Signs posted midchannel by the Board of Health discouraged canoes and kayaks from paddling up river. Dredging up the sediment and removing the lead has made it possible to now eat the crabs and shellfish, and birds are born without birth defects. The chrome-plating company across the river from the battery plant has been in operation since 1946. It does not seem to have had runoff and other environmental problems, despite the toxic nature of their materials. Environmental cleanup is expensive, and there are reasons for having laws that keep pollution from happening. Having clean air and water means fewer illnesses and lower medical bills for everyone. If it makes small-scale galvanizing less profitable perhaps the solution is to consolidate chain from several boats and have it all done at once. There's more than one way to skin a cat. (Don't tell PETA I said that.)

Re: Chain galvanizing

I live in Philadelphia and looked around pretty hard a few years ago. Long story short I could. It find any place to do it. I even carted the chain to a guy in Newark, NJ who has some new tangled process. After testing the chain and finding it good he let it set in his shop for a few weeks and then said he was not interested. I bought new chain.

BUT....there is a guy in Rio Dulce who does it. Great excuse to go there!

Re: Chain galvanizing

Baltimore Galvanizing and Southern Galvanizing, both in Baltimore, are still in business and both do hot dip galvanizing, which is the best. However, if your anchor chain is really rusty, it will have to first be sand blasted in order for them to galvanize the chain. The cost of both the cleaning and galvanizing may be cost prohibitive, making it less expensive to purchase a new chain from a reliable, and inexpensive source.
