Aluminum casting into hot dip galvanised tube -outdoor use

I am engineering an outdoor application - seating structure

I have an aluminum casting which spigots into the top of a mild steel tube, the plan was to hot dip galvanise the tube first , then press fit the aluminum casting into the top of it

I am concerned that galvanic corrosion will occur leaving nasty corrosion marks

does anyone have any suggestions to alternative coatings on the steel tube so it's not zinc next to aluminum

thanks,

A. Black epoxy CED ⇦ huh? coat always looks good on seating systems and will not cause Aluminium to oxidise.
