Corrugated Galvanized Steel Roofing
The corrugated galvanized steel roofing has a double-sided coating weight of 20-275 g/m2 according to ASTM test. The most commonly used corrugated galvanized steel sheets for building applications are Z275 and Z450, and the galvanizing amount is 275 g/m2 (the minimum thickness of the single-sided coated of the steel sheet is 19 μm) and 450g/m2.
Corrugated galvanized steel is one of the strongest, most durable roofing materials, since it lasts longer, is more resistant to wind, and absorbs less heat than asphalt shingles.
Does galvanized roofing sheet rust?
So does galvanized steel rust? The answer is yes, but very slowly. In fact, slow enough that it's usually not a problem.
This is why galvanized steel has been in use for the last 2,000 years, and why it's probably going to be okay in your application
