Early Steel Bar Joists
Early Steel Bar Joists
(OP)
I've got a building built circa 1938, and has SJ81's for floor joists. Anyone know what the seat height may be on those? And what the top and bottom chords are? The chords look like rectangular steel bars on the flat from the 1 picture I have.

I got this from the SJI publication "Steel Joist Institute 60-year Manual"
