I'd wonder if the test certificate was not available for the batch. Given that you find chain that is strong enough I'd then look at galvanising thickness, as thickness largely determines how long it the galvanising and hence chain will last. Practical Sailor has an article on galvanising of chain and how to easily measure it in their January issue. The Practical Sailor article concludes that the best chain, price, galvanising, strength, is from America having looked at American, Maggi , Oz and Chinese supply and G There is an earlier PS article on chain strength.

Peerless, one of the biggest traditional manufacturers have just introduced a metric range of chain but only in G40 and G70 quality not G American chain tends to show less, actually no, flaking of the gal than Chinese or Italian chain. Noelex might have said, if you look at his chain size vs vessel size, that he is using G70 chain and I believed downsized from 12mm to 10mm.

The electronic Jan issue also has a nice Blog as intro to the Fortress Chesapeake tests to be published for their Feb issue. J Neeves said:. OR That's a decent certificate just get one for the batch you buy.

I might still check on the galvanising. Differences in quality of gal can be a factor of 2 and 2 times as much gal means the gal will last much longer, though maybe not 2 times as long. Gal can vary within a manufacturer and from batch to batch. I'd also guess they are keen to make some sales progress as the range was only introduced a couple of months back - maybe they will be really price competitive. Again if you have difficulty at Peerless send me a PM and I'll dig out a contact for you.

Last edited: 16 Jan They'll provide you with bona fide certificates which, I'd rather suspect, would be more difficult for Jimmy Green to access. Wm Hackett, in Cradeley Heath are still making chain. The 7mm chain bought the year before, in Spain, has had about immersions and is showing signs of wear. Customs and Excise have few limits on their powers and if you've ever been "turned over" by them you'd be unlikely to invite their inspection.

William Hackett now own Bradney Chain. Both import smaller sizes, including 10 mm, from China. They carry out a certain amount of batch QA testing and may possibly carry out proof testing if asked but it will cost. Jimmy Green import from Maggi in Italy, certificated and with proof testing I believe, plus it is possible to buy direct from Maggi.

I don't know about Griff as they have declined to send me samples for testing, which makes me suspicious. You also have the option to opt-out of these cookies.
