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

There’s also hot-dip galvanized and stainless steel rebar.

... with stainless being a much better (but much more expensive) choice.

HD Galvanized is a coating whereas stainless steel is a different material - it is stainless all the way through ...

It's a coating, but my understanding is that it basically creates a battery that keeps the nearby iron from deteriorating. Small gaps in the coating therefore don't really matter as long as there is still some zinc nearby.

Yep, I believe that's the same mode of operation. The definition of galvanic is, "relating to or involving electric currents produced by chemical action."
