If this is from the same family and era, I would be a bit suspicious. The
standard beam series only goes up to a maximum flange width of 6.25". The
flange width of 6.75" indicates this to be a Bethlehem Beam B series. The
closest fit would be with a B15x36.0 with a web thickness of 0.280" and a
flange thickness of 0.355". This can be confirmed if you measure the flange
thickness at the flange gage line at 0.50".
Ix = 410.9 in4
Sx = 55.12 in3
Iy = 21.7 in4
Sy = 6.45 in3
How sure are you of the measurements? It is best to scrape the steel as
clean as possible removing paint and mill scale in spots and measure with a
caliper at multiple points along the length of the beam. I would measure
the flange thickness at the edge, the flange thickness at the gage line,
depth, and the web thickness in a few spots. The web thickness is a bit of
a challenge to measure with accuracy. I would venture that it is likely
that the web thickness measurements have a good probability of being
Sounds like a B15x36.0, with a fairly high carbon equivalent, local
crystalline lenses through the cross section, cast in Pittsburgh,
Pennsylvania, 1933, probably the last Wednesday in October, north side of
the mill, with a shift supervisor named Raul (married with 3 children).
Sorry.... I just got a little carried away. Ignore this last paragraph.
