Very good point, Bob, thanks for refreshing my memory. I have had contractors, who do there own bar bending, request more smaller diameter bars in lieu of less larger bars. Most portable benders will not bend anything bigger than a # 5, so if a bar is going to be shop bent, it would not make much difference if it was grade 40 or 60 from a bendability standpoint. Most stirrups are always bent in the shop and so the grade availability is usually not an issue. Like you said, when a contractor says grade 40 is not available, that probably means from the supplier *he* has an account with or that there is a 3 day lead time from some other source.
