Yup - when tin work was popular it was very common for it to be soldered. I know tin isn’t exactly steel, but it has similar properties. I’ve soldered galvanized sheet metal, but I can’t remember what for. Used a torch, lost of plumbing flux and heavy solder.
Yep and the answer to that one is in the composition of the galvanizing material.
