I'm building a cedar picket fence attached to 2 3/8" chain link fence style galvanized steel posts using galvanized post brackets like these. I know that there are a lot of material incompatibility potentials here, so I want to make sure I get it right.
I know that galvanized fasteners corrode in cedar and cause ugly stains, but will it be a problem to have galvanized brackets simply touching the cedar rails on the surface? Should I "downgrade" to spruce/fir/pine rails in order to reduce corrosion of the galvanized hardware that will be touching them, or physically isolate them from each other with something?
If I use stainless steel screws to affix the rails to the galvanized brackets, will that create a galvanic corrosion potential? (the galvanized brackets will be the anode)
