I left galvanized sheets together in the rain, now they are black. Is there any way to return them to normal?

This is typical of galvanized steel, as it will often become discolored after left to the elements. The black or brown color you describe is purely aesthetic and does not affect the stability of the steel at all. If you don't like the color, you can paint over it.
