Attaching Treated Plywood to an Aluminum Frame

I am helping someone attach 3/4" treated plywood to an aluminum frame for flooring on a boat. Knowing there are corrosion issues with treated plywood and different types of metal on metal contact I am concerned with which type of screws would work for this. Would galvanized screws work with both the plywood and aluminum?

If the plywood has been treated with copper compounds (most likely) I'd use stainless steel screws, however if the plywood stays wet, expect some corrosion problems with aluminum. Reinforced plastic grating would be a better solution.
