Help Identify this unusual steel joist
(OP)
See attached photo.
constructed in 1962 in Norwich, CT
2.5" seat
spans about 20'-8"
joists spaced at 48"
12" depth
top and bottom chord are 5.25" wide, 1.25" tall, and 1/8" thick
somehow I doubt this is from an SJI member.
see attached photo.
thanks for any insight.

You can get it from SJI as well. I use their forms when verifying existing joists and they are always helpful.

I have not heard of any recent issues with the joists fabricated with hat channels, but whenever I see a roof with similar construction that story always tends to creep into the back of my mind.
Personally, I have not come across too many structures with the SJ type of joists, and the ones I have seen did not express any significant deterioration.
The company I used to work for in NY used to use an ultrasonic thickness gauge to test for deterioration in these types of members.
