It does not make any sense that it would be done in galvanised unless it was done prior to the rest, which is strange.
I would use the brass fittings to make the transition, brass oxcidises slower than copper. Are you going to go all the way to where the galvanised starts? or are you just going to branch off under the sink... i mean if the rest of the house in in copper, where does the galvanised meet the copper?
