It seems the material is big enough to make my 70"x7" ac drain plan
I think we have a set of sheet metal rollers. You should be able to flatten it pretty reliably by running it through the rowers once or twice on opposite sides.
I need to check. I may have a roll of continuous gutter material, which should be the same width as that stuff flattened out. If I still have it the stuff I have is painted brown on one side bare aluminum on the other.
Why? Like seriously just buy a flat sheet from metals4u and bend one up

I have a coil of brown polymer coated 24 inch wide material. I’ll sell you seven or 8 feet for $15.
