Even with a little nasty surface crud and corrosion, aluminum rails are still plenty strong enough to be run out of town on. But if you want to preserve them right, get them anodized (blue would be nice), or do the alkali soap, acid wash primer, zinc chromate, and acrylic lacquer topcoat thing. Then they'll outlast the piano to about the same degree as if you hadn't treated them with anything more than a few small rodent droppings - unless someone cross threads flange screws and strips them out.
