Does anyone know of a source or sources for custom louvers? I am looking for someone to form 2, 6" long louvers in a piece of 18-gauge steel sheet (8.5" x 7"). I need 2 sheets like this. Louver spacing between the 2 is open but I would like them as close as possible to one another as long as louver forming is not hampered.

I just realized that the material I need may be 16 gauge versus 18 so I'll need to measure to e sure.
