How did you solder it and with what? Does soldering not remove the galvanized coating?
Use a tinners iron - I have an electric one - the original "tinner's
iron" was heated with a blowtorch. Flux the galvanized and solder it
together - the zinc stays on the steel.

DON"T try soldering it with a torch. You WILL burn off the zinc, and
it will rust bedause you will overheat the joint.
