It is used for other things besides bridges and that might be a bad use. Corten was used for very tall light standards in the Fort Worth Water Gardens with the clear understanding that it was to be kept dry. As time passed and personnel changed, somebody decided the round base with bolts sticking up was ugly and put dirt and plantings in the basin in the concrete holding the poles. The watering of the plants kept the rust going through the steel and one pole eventually fell, killing two people. The other light poles were removed.
Do you mean galvanized steel?
