In practical terms, zinc is joined by mechanical rolling and crimping,
rather than by soldering. It can be soldered (and for French cafe
tables, it was) but it's a bugger of a process, particularly when
outdoors.

I made a new zinc tray for the top of a bay window which has a recessed
flat roof ages ago and don't remember having problems soldering the seams
to make it watertight. I used a Camping Gaz blowlamp which has a solder
bit attachment rather than direct heat. Ordinary engineer's solder and
Bakers fluid. Don't remember it being any more difficult than soldering
other large sheet materials like tinplate.
