Fire ratings are generally based upon testing of a structural sample. A galvanized sheet, by itself, would not have a fire rating. If combined with gypsum or other materials in an assembly, it could be subjected to the standard tests and rated for use in that configuration.
That said, 1.5mm sheet steel can be used in assemblies rated 1 to 4 hours.
