The only question is what material to use from the Home Depot metal bin?

Aluminum step flashing is sometimes pretty stout. Aluminum siding parts,
perhaps.

They do have a metal bin that might have stainless sheet metal.

They have sheetrock mud pans and putty knives that are cheap enough to chop
up, and some of the mud pans and perhaps putty knives are stainless.

I would not think you would want galvanized, but if you did, there is more
of that stuff than you can swing a cat and miss.
