All I've found there was rolls of 24-inch-wide flashing, in the roofing section.
It could be used on 'curves', with formers, stringers, and hat-section bonded or riveted to the inside surface, otherwise, it would be way too flimsy.
We have a few metal recycling centers which still allow salvage.
Retired, commercial, aluminum signs sometimes show up, and the material is thick enough to span 24" between supports. The diffuser on the truck is a single piece, with t-section pop-riveted on the backside.
