One of the A.I.S.C. manual of steel construction, A.S.D. (Allowable Stress Design, or the Load & Resistance Factor Design L.R.F.D. might help you after you determine the shape, the letter designates the shape say like a "W" then the web is next say 12, then the last number designates the weight per foot, so a W12 x 26 is a W shape, has a 12" web and weighs 26 lbs. per foot.

I have not looked at any of these in a few years, since I left the hustle and bustle of the high rise building cosntruction industry, but they are good reference books, when you need to know something about steel construction.

If you intend to span something with this beam, and it has to carry a load, I have always been of the opinion that an engineer should look at the details one proposes, to insure that it's ok for the loads imposed on it. It's safe practice and they range from $50 to $100 an hour around here, should not take long to analyze a straight forward detail if all the components are give.

I should refrain from lecturing or pontificating here, but it's important to know for safety reasons, I spent good part of my career, fixing details that did not work in the field, using my knowledge and reference materials, to revise things per field conditions or suggest details for things overlooked in design, that arise in the field during construction, mostly connections and fasteners but also some significant spans, in some instances, all of which were always approved, signed and stamped by a qualified licensed professional engineer after analysis.

You might find an edition of those manuals in the local library and it may shed some light on what you are dealing with, am curious what you are building as well. I see editions on e-bay quite often, older ones are affordable, newer ones are $200 or more.
