Steel to Aluminum Connection
Steel to Aluminum Connection
(OP)
This may not be the best forum but one thing I know - you guys have seen it all and respond quickly.
I have a primed steel to aluminum connection on interior of building. So it will always be dry. I have no trouble with the connection design - but now the owner is worried about corrosion or galvanic action or whatever.
I don't believe this to be a problem - at least for the next 100 years or so. Your thoughts please.

RE: Steel to Aluminum Connection
Galvanic action of dissimilar metals, it is; and if you eliminate the electrolyte (water) you probably do eliminate most of the problem, but not the potential (that's not a pun). I think we used some thick bodied paints, or some such, which acted as a separating layer in the joint, between the two different metals, if the joint design will allow this. But, then you still have the bolt issue, stainless? Maybe ...Connecteng... will chime in here, he will have seen this problem more recently than I have.
RE: Steel to Aluminum Connection
Once the first passivation layer of the aluminum develops, you have an inherent moisture absorptive layer that will allow the galvanic process to continue.
Isolate them as best you can.
