Sheet Metal Fire Rating

Does anyone know if there’s a CA code approved fire rating for certain gauge sheet metal?

I know there are tons of products out there, and I’ve already chosen the product for this specific job, but it’s another question that I’ve always wondered about.

Any ideas?

Re: Sheet Metal Fire Rating

Fire ratings are based on an assembly. One sheet of 5/8" Type X sheetrock has no fire rating. But when it is used (one) on each side of a properly framed wall, it can become a fire rated wall.

I am not aware of a fire rated wall assembly using sheet metal. Sheet metal penetrations are used in rated assemblies, and when correctly fire-caulked become part of that assembly.

Rated floors often use sheet metal pan decking, most often with a pour of light weight or standard concrete on top.

If there is it will be something with a high carbon content.
