History of galvanized sheet metal.

Zinc coated steel is protected from aggressive external influences but be aware that the surface layer is also subject to corrosion only to a lesser extent.

The mint was thereby fireproofed with a 20gauge galvanized corrugated iron roof on iron trusses. When exposed to the atmosphere the pure zinc zn reacts with oxygen o 2 to form zinc oxide which further reacts with carbon dioxide co 2. Galvanized steel is suitable for high temperature applications of up to 392 f 200 c. Use at temperatures above this level will result in peeling of the zinc at the intermetallic layer.
