Unless there's a good reason to use stainless (eg corrosive environment) why would you consider it? Galvanized steel and stainless steel are similar strength and galvanized is cheaper. Also easier to work, wrt welding, thread spalling etc.

Nononononononono! Don't weld galvanised steel! The fumes are highly toxic!

Cold-dip galvanise after welding and clean-up? No problem.

OK, I always thought the zinc burnt off and you could weld as normal, but I'm no expert on welding.

I. CHEMICAL AGENTS

ZINC

Zinc is used in large quantities in the manufacture of brass, galvanized metals, and various other alloys. Inhalation of zinc oxide fumes can occur when welding or cutting on zinc-coated metals. Exposure to these fumes is known to cause metal fume fever. Symptoms of metal fume fever are very similar to those of common influenza. They include fever (rarely exceeding 102o F), chills, nausea, dryness of the throat, cough, fatigue, and general weakness and aching of the head and body. The victim may sweat profusely for a few hours, after which the body temperature begins to return to normal. The symptoms of metal fume fever have rarely, if ever, lasted beyond 24 hours. The subject can then appear to be more susceptible to the onset of this condition on Mondays or on weekdays following a holiday than they are on other days.

Thanks, the implication of that is the welding still works OK. It wouldn't surprise me if welding of galv steel goes on. If it's outdoors (structural steel likely to be) keep upwind of the workpiece. If indoors, use an ordinary fan to disperse fumes. Keep other workers out of the way, of course.
