Conclusions
When Frank Lloyd Wright designed Fallingwater, he must not have specified a steel grade or condition that varied from common production available. Yet, it is notable that the Bessemer steel reinforcing bar had not deteriorated during service in the concrete terrace. Also, the open-hearth hatch steel performed well, as severe corrosion occurred only at the concrete-bar interface while the remainder of the flat bar, also exposed above the Bear Run stream for 68 years, showed only pitting corrosion. Fallingwater has timeless interest as an architectural achievement, and some of the steel used to produce this landmark was made using techniques whose time has passed.
