Macomber Steel Joists 1963-1964

[jim57]

Need to determine what size my bar joist is. i have the Macomber Steel Joists 1968 manual with the cross sections. This is different from what I have. Does anyone have a catalog for 1963-64 ?

Thanks

Contacted the SJI and they identified it as Macomber. The web is 0.87"t diameter bar. No uprights in web except at end of span.
