What is the fire rating for the 8 ft. Corrugated Galvanized Steel Utility-Gauge Roof Panel?

Here is some information about fire rating.

Metal Roofing Fire Resistance Ratings Gibraltar's metal roofing panels have been analyzed for fire resistance ratings according to test criteria set forth by Underwriters Laboratories “Standard Fire Tests of Building Construction and Materials” (ANSI/UL 263) and ASTM E119 and NFPA 251. The fire resistance rating is for the total assembly and not just the external metal roofing panels. In general, the test criteria is to evaluate the assemblies ability to continue to support the imposed loads and to resist the passage of flame, high temperature, or hot gasses which will ignite combustible sub-assembly, framing, or decking materials from an exterior source. For detailed information on specific assembly ratings see the UL Fire Resistance Directory.
