If you can post the span and spacing, I can look and see what the ratings were. I believe that BAretired has another catalog too...

They'll poke through the catalogs and tell you what you have.

I am in Virginia and have dealt with the Reidsville, NC Butler office a few times.
RE: Help ID this roof steel joist
You may have to measure it up and analyze. You would also need to know material strength.
Call Butler if you suspect it was theirs. SJI can also help.

Anyway, thanks SteveG!
I now think this is a Butler truss purlins, with lips on the flanges and double diagonal webs toward the end/seat, identical to what SteveG posted.
I just contacted Butler.
Thank you everyone for all the help!
RE: Help ID this roof steel joist
Yes, this is a Butler truss purlin. He communicated directly with me and now has the design data information for the joist in question.

I wish every PEMB mfr. is as responsive as Butler.
RE: Help ID this roof steel joist
Butler has just introduced the Truss Purlin XT. This is an update to the existing truss purlins which uses a bolted joint rather than a welded joint between the web and chord elements. Members depths are 30", 34", or 40". Spans to 60'. These are designed per order for the specified design loads.
