In short, No - in the UK "Class 1" is a form of performance that indicates how easily something burns ('Class 4" being the worst). Fire resistance on the other hand is a term that relates to a construction's ability to resist the passage of fire (e.g. a wall, floor, door etc). The fact that a material is "Class 1" doesn't necessarily have any bearing on its fire resistance performance. For example, PVC cladding can be obtained to a 'Class 1' rating, but it wouldn't contribute much to the wall's fire resistance performance at all.

Sheet metal typically has a fire rating of Class A, which means it is highly resistant to fire and will not contribute to the spread of flames. However, the specific fire rating can vary depending on the thickness of the sheet metal and any fire-resistant coatings that may have been applied.
