Old concrete non-deformed rebar
Old concrete non-deformed rebar
(OP)
At my father-in-law's house, we stumbled across an old concrete foundation with exposed, non-deformed rebar. Any idea approximately when the transformation to deformed from plain rebar was made? (1920s?) This is in southeastern USA.

I also have an 18" piece of the #14 bar for one of the roof ribs of the Kingdome taken at a cadweld joint. Has to weigh at least 40#.
It's amazing what we save as memories. And we wonder why we have too much stuff...
Can't help as to when the change was made though. Others can though.
