origin of old large tapered flange beam?
(OP)
I am interested in finding out the likely origin of a large taper flange I beam (as a born and bred Brit I would normally call it a RSJ). Overall depth 910mm (35.8"), width 420mm (16.5"), web thickness 20mm ((0.79"), flange 28 to 37 mm (1.1 to 1.5").
I am only asking out of plain curiosity (we already know the steel strength and have calculated the section properties); I have never come across such a section before. (And "before" covers a fairly long span
).
None of my references show RSJs (would these be called S beams in the USA?) anywhere as large as these, which have been procured by an Aus contractor, who intends to use them for some temporary work.

I looked and cannot find your beam exactly. However, there are beams listed which have properties that are very close. Considering rolling tolerances your beam is probably listed.

You may well have got it. I hadn't realised that a UK UB might have a tapered flange.
Is that the meaning of the # and + signs in the section name for the largest UBs when I read the BS Section Properties at http://www.corusconstruction.com/indexes/idxpr003.htm ?
RE: origin of old large tapered flange beam?
The # sign indicates a British standard section which is not rolled very often and availability may be difficult.
