Can aluminum extrusion framed wall system be used in a galvanizing plant?

A. Galvanizing plants have large tanks of acid, often open topped to atmosphere inside the plant.
Typically in Europe hydrochloric acid, and often in the Americans sulfuric.
Perhaps ironically, corrosion of the building is a big issue in galvanizing plants (which of course are set up to corrosion protect steel).
I would not advise any exposed aluminium anywhere inside a galv plant.

A. What you should be concerned about is the fumes from the pickle tank. Sulfuric Acid doesn't fume anywhere near as much as Hydrochloric Acid (Muriatic Acid). You could take a look at their existing installation to see what problems they have encountered in the recent past. Now, let me step up on my soapbox (thank you for the opportunity) and say a few words. Zinc platers and galvanizers are in business primarily to put zinc on steel to prevent it from rusting. And yet, when you go into almost all platers and almost all galvanizers, you see exposed steel - rusting, and in many cases (due to hydrochloric acid fumes and condensation) rusting badly. I never thought this made any sense at all.
