Looks like the beam may be an American Standard shape (as opposed to WF, Junior beam, etc.) There is a 24x7 @ 100 plf which has a flange width of 7.247", flange thickness of 7/8", and depth of 24.00". There is also a 24x7 7/8 @ 105.9 plf which has a flange width of 7.875", flange thickness of 1 1/8", and a depth of 24.00". I would probably opt for the first one. As for the column, all the 8" x 8" WF sections appear to have a thicker flange than what you measured. I found a "light column" shape which has a flange thickness of 7/16". I will fax the applicable pages to you at the number given in your original e-mail. Hope that helped, Mike Ritter, PE
