Attaching aluminium roof sheeting with galvanized screws

I have a doubt, If we using galvanised self tapping screw for fixing the aluminium roof sheet is it acceptable ? If there is any corrosion issue ? Please answer.

With no other information, my guess is that it is not a good idea. Steel beam, Aluminum roofing and galvanized fasteners.
Without looking it up, I think that the galvanize will go first.

No, do not use them. Galvanized fasteners are not compatible with aluminum. You will create a galvanic reaction
