HDG fasteners on bare steel - Buffer?
HDG fasteners on bare steel - Buffer?
(OP)
Due to galvanic corrosion I'm aware that HDG bolts attaching bare metal beams-to-columns is a no-no. I have primed beams/columns fastened with black bolts. Obviously the bolts tend to start rusting/streaking prior to the primed material in an exterior environment. Are there reasonable "buffers" out there that would allow me to use a HDG fastener with a primed steel plate connections? Even if there is a buffer, what about where the bolt/plate bearing occurs? I'm just trying to learn what others have done in similar situations. HDG'ing the beams and columns isn't an option unfortunately. Would it make sense to prime what is exposed of the completed connection?
Thanks.
Thanks.

It for sure wouldn't be worse than black bolts.
