If you leave the steel bars against the aluminum structure, corrosion will set in as soon as a little moisture condenses in between the two different metals. Basically, it's the same chemistry that is used in a battery, only slower.
Better to use aluminum to reinforce the rib and stop the reaction before it starts. Otherwise, use plenty of corrosion-resisting paint between the aluminum and the steel.
