The galvanizing process explained?

I am currently writing a play that involves the discussion of the galvanizing process for nails.

How many people are going to want to watch a play about nails, you ask? Well, for a short time in the late 70's I worked as a galvanizer at the Independent Nail Corporation in Bridgewater, MA. I am using the process as a second story line in my play and I am interested in getting information about the actual step by step process of the procedure.

While I remember having to slowly(!) dip the nails into a big cauldron of bubbling zinc and then wash them off after they came out, I am unsure of the process before they arrived at my station. I DO remember that they had a terrible acid-like smell. Any help that you could give me in this search would be greatly appreciated. Thank you for your time.

Sincerely,
Jack

Hi, Jack. The nails would be cleaned in a caustic cleaner, pickled in hydrochloric acid (which is the acid-like smell you speak of), dipped in a flux sort of like what is used for soldering, and then go to your work station for dipping in the molten zinc. After that, on to rinsing, probably with a dilute chromic acid.

Break a leg, and let us know when it gets to Broadway!
