It can be pretty HAZARDOUS to your health for long term exposures.

Super bad. Every place I've been at where they were welding galvanised metal the welder wore a helmet with fresh air being pumped into it.

Dangerous because of the Zinc used in galvanising

try this link:
http://en.allexperts.com/q/Occupational-OSHA-Environmental-1417/galvanized-steel-fumes.htm
here is an excerpt:
"When zinc vapor mixes with the oxygen in the air, it reacts instantly to become zinc oxide. This is the same white powder that you see on some noses at the beach and the slopes. Zinc oxide is non-toxic and non carcinogenic. Extensive research into the effects of zinc oxide fumes has been done, and although breathing those fumes will cause welders to think that they have the flu in a bad way, there are no long-term health effects."
hope that helps

bad enough to insure you have adequate ventilation as you should for all welding jobs. all welding fumes are dangerous. do some arc welding for an hour in an enclosed space and see the crap you cough up from your lungs. if in doubt about your safety dont do it unless your 100 percent sure yourself,

There is a clue here.
Fabricate then galvanise?
The process is achieved by making one the anode and the other the cathode.
So what is the coating ???

The fumes can cause irritation to the eye, nose and throat. The inhalation of excessive zinc fumes can place you over the permissible exposure limit and cause metal fume fever. Ozone can also be emitted and prolonged exposure to ozone can cause lung damage.

Dangerous enough to kill you, given time. Grind off the galv before starting the job, then replace the galv protection with 'Galvafroid' spray, or something similar. Visit the web site of the Health and Safety Exec and ask your question there. If your employer insists on this method, report them to the Exec and they will do something about it.

my hubbies a welder, he says they're VERY BAD, they will give you flu like symptoms & head ache, can even make you vomit. In worse cases you could pass out!
ALWAYS wear a mask, or better still get a qualified welder to do the job for you.
If you have breathed the fumes seek medical advise A.S.A.P
hope this helps.
