There are about 4 sections listed in the AISC "Iron and Steel Beams, 1873 to
1953" that could be considered B20 X 59. All of them have about the same
properties and were manufactured between 1907 and 1921.
A 17.15 to 17.36 sq. in
Depth: 20.000 in.
I: 1169.7 to 1176.3 in^4
S: 117.0 to 117.6 in^3
Hope this helps.

Does any one knows what it is equivalent to a shape
in green book. Where can I find the properties of
this on the internet. Any and all help will be really
appreciated. Thanx a million in advance.<<
