Historic shapes pre-1930's
Historic shapes pre-1930's
(OP)
I am evaluating an existing building in Canada and I encountered steel shapes that I could not find in any available references. not even in 1934 AISC, old CISC handbook etc.
the beam shapes are mostly 27I160, 27I145, 27I101, etc. (note that I/S shapes commonly comes up to 24" only, even in older AISC databases). I have also smaller sized I shape beams, 18, 12, etc. but does not nearly match in any shapes database. Columns are problems too, 12H75, 12H40, 12H100, 12H130.
field measurements can be a bit difficult, over 80 years the steel beams and columns had been coated several times with thick coating to prevent very high corrosive attack from sulphuric acid (a 99% pure H2SO4 plant).
could anyone have these kind of I and H shapes database? or at least what steel mills these shapes came from?

"AISC Rehabilitation & Retrofit Guide, A Reference for Historic Shapes & Specifications"; Steel Design Guide Series 15.
The "H" sections are there. They are listed as Carnegie Beams (CB). There are no 27-inch "I" beams but there are 27-inch Carnegie Beams and wide-flanges with the same weight.
