Frequent Rio Problem- corroded metal


These "big ears", as the telephone booths are known, came crashing to the ground one night after the corroded pole that was holding them up finally gave way. I see sights like this all the time in Rio. The most conspicuous to me are the numerous pull up bars that are always falling down. Maybe an engineering friend could tell me if it's the climate, just old metal, or another reason. I'd like to know.

Metal to close to the ocean becomes corroded very fast. An alternative would be to use anti corrosion iron but that is way too expensive.

The ideal solution is to use regular steal (or other metals) and simply replace them faster before corrosion completely destroys things.
