You wouldn't want to put those against your galvanised trailer chassis

Lol stainless and galv. No no no


Galvanised steel is simply mild steel which has been dipped in zinc. Which again forms a protective non porrous barier to oxygen.
If the galvanised layer is broken or damaged corrosion will occur at a faster rate than normal due to galvanic action between the zinc and the mild steel in contact with oxygen.
Placing stainless steel in contact with galvanised steel will cause increased corrosion in the metal which is higher on the noble table of metals. The higher a metal is the more it will corrode in contact with a lower metal.

I think you are a bit confused

"Galvanizing is the process of applying a protective ZINC coating to steel".

Also the corrosion you are referring to is in fact due to "crevice corrosion".

*Shrugs* we can buy them easily here in the USA. West Marine stock them a couple of miles away from me. I usually buy from Amazon for half the price.
