No mention of epoxy coatings for steel rebar? Look for green-coated rebar as you pass highway construction sites.

That certainly helps, but in some cases such as when the rebar is under tension the epoxy coating can result in unexpected failure if there is any damage to it. The small areas lacking coating are corroded more aggressively, resulting in deep pitting which can weaken the bar to the point of failure.
