[b]bold[/b]Old Steel Beam Specifications
(OP)
I need to find specifications (hopefully free on-line download) for old steel beams, girders, and columns- for example a 20B59. I have structural drawings from a 1920's building in Brooklyn, NYC but no details. [The building is the St. George Hotel- which some of you may have visited years ago for a wedding or other event]. Thanks

(Or, if you have only a few sections to find, I can fax some pages to you if you get me the information).

I know the Saint George. It used to be the dorm for the school I went to, Polytechnic Institute of New York (formerly Polytechnic Institute of Brooklyn; now Polytechnic University)
