I am in charge of a project to restore a 75-year old awning at a
Federal Building in Washington, DC. The awning has a copper sheet roof,
which runs across 2"x1/4" galvanized steel flats placed on edge, (i.e. with
the 1/4" surface at top and bottom) at a slope, average 14" apart, in contact with the copper sheeting which wraps over on either side, so that between these
flats, the copper sheeting is at about the same level as the bottom of the
steel flats. It is proposed to replace the corroded steel frame and flats
with new galvanized steel material. The copper is found to be in good
condition.
Could you please suggest a suitable and lasting product to be used as an
interface membrane between the galvanized steel and copper, to be wrapped or
coated over the galvanized steel, so as to prevent electrolytic corrosion?
Thank you.

I would suggest contacting the Copper Development Association for their input but right off hand I would suggest a quality rubber membrane of some sort.
You could also conside stainless steel rather than galvanized anmd that might help.
