Rust & corrosion can seriously reduce the strenghth of metal if left untreated. The best protection for metal is to maintain the bare metal with a primer and topcoat, thus avoiding or at the least, slowing down any corrosion. If the rust had started to form already, due to lack of maintenance, the rust would need to be treated with a rust treatment. Then a primer could be applied to protect.

There is a few extremes depending how you look at it - A car rusting will fail a road safety examination (MOT Test in the UK), but a bridge failing due to rust would be a disaster. There is some examples of bridge failures on wiki.

Hope this helps.
