(OP)
A project specifies galvanized ASTM A53 grade B pipe for handrail. Must this handrail be welded with GMAW (mig) or can SMAW (stick) be used?

It depends on if you are talking about shop or field work. I agree with david's post above for shop work, however if you install a galvanized handrail in the field SMAW would be better.
Be sure to protect your welders from zinc fumes either way. A proper respirator should be worn during welding. Zinc sickness/poisoning is pretty nasty.

DVWE - Thank you; this will be field welded - so SMAW would be better?
RE: Welding galv. ASTM A53 gr. B handrail?
Ideally Fabricate from bare steel, Hot dip Galvanize after, mask off areas to be field welded.

You are judged not by what you know, but by what you can do.

Even with grinding, protect the grinder/welder from breathing the grinding dust.
Yes, SMAW will be best in the field.
