I assume you're referring to fire ratings.
UL Fire ratings are assigned to individual products on the basis of testing.
Under the ICC, though, I believe that all steel roofs receive a Class A rating.
Some products may require a certain fire resistant underlayment to achieve Class A but most metal roof systems will be listed for Class A.
