"Do you mean MC3x7.1 (tw=0.312", bf=1.938") and MC4x13.8 (tw=0.500", bf=2.500")? They're in my Ryerson catalog, but it doesn't list the flange thickness. My AISC 7th edition gives 3/8" for the average flange thickness of the MC3x7.1"
Yes those are the shapes I am referring too. Ryerson...
Would any of you have reference to the cross-sectional dimensions of these 2 channels, MC-3 and MC-4.
Ryerson still supplies these 2 sizes but does not give the dimensions. I am drawing them in Solidworks but need the angle of the legs.
THANKS.
