Aluminum chainplates

[Brian Duff]

I think that overall aluminum is a better choice than stainless steel for any structure to be used in the marine enviroment. It doesn't suffer from as serious, and hidden, corrosion problems as stainless steel does. Aluminum shows its corrosion quite clearly, where stainless can dissolve deep while still appearing to only have 'surface corrosion'.

Reproduction of these chainplates should be an easy job for any machine shop.

The comments about the seperate deck plate have merit due to the serviceablility of this type of installation - a leak can be addressed without removing the entire chainplate. Thats a plus.

Using plastics to isolate the aluminum from the stainless steel where possible is always a worthwhile effort.

Good Luck.
