Galvanized Angle and Stainless Steel Anchors
Galvanized Angle and Stainless Steel Anchors
(OP)
I have a condition where I need to bolt a steel angle to concrete. This angle will hole up a floor. It is a location on the inside of a cut off wall (fresh water). The wall will leak a little, but for design I am assuming it will be wet for long periods of time. I don't like epoxy for sustained tension loads so I am looking at expansion bolts.
The angle will be galvanized. The cracked concrete approved anchors available appear to be stainless. The is a galvanic corrosion condition with this condition, but most of what I can find indicates it is not a concern except in some marine conditions. While I don't think this qualifies as marine, I do think it is worse than your average exterior application.
What do you all think about the corrosion potential for this?

1) A galvanized substrate is ok with any kind of fastener.
2) A stainless steel fastener is okay with any kind of substrate.
This is from the perspective of fastener corrosion only. I believe that the substrate is assumed to be ok by virtue of the ratio of anode to cathode argument.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
