Steel Bar Joists Tag Identification (photo included)
(OP)
There is a warehouse who's roof is significantly deflected (due to large amounts of snow) and I'd like to not go back inside to identify the steel roof joists. The building is currently evacuated due to the roof deflection.
Here is a photo of a tag from the bar joists:

As best as I can read it says:
MACONDER-ALLSPAN
C 28423 RED
826A 40 4 A
Anyone have any idea what brand or any information that would be helpful? The building is built around the 1950s. Thanks!

Time to do some digging. The tag doesn't seem to match up with the 1970s manuals. But, I have a great start! Thanks again.
