13" 52.5# Car Builders Channel - Dimensions Quest

13" 52.5# Car Builders Channel - Dimensions Quest

(OP)
Hello:
I am looking for the dimensions of an old steel shape commonly used during the early part of the 20th century, the 13" 52.5# Car Builders Channel.  I have looked in the Bethlehem and Carnegie books, but the furthest back I have date in the thirties and do not list this size.  I suspect its use did not continue after about 1920.  I especially need the web thickness, but could use all of the general dimensions if anyone has them.  Thank you in advance.

In my Cambria book, I have 13x50 and 13x55, but no 52.5.  tw for the 50 is 0.79" and for the 55 is 0.94", for what it's worth.

Before this thread drops to the second page, I couldn't find anything in my material...

From other info I have it appears that a tw of 15/16 would be correct.  Thanks for looking into this - I am actually surprised that I can not find the info anywhere as it appears that it was a fairly heavily used size at one time.

Nick,

I'm sorry but I can't find that shape. It's not in the AISC historic database. I also looked in several steel manuals from early 20th Century with no luck.
