In terms of unit material spent my impression is that an I beam uses it most efficiently at least for non-torsional loads? i.e. putting most material far from the axis into the flanges giving higher moments.
If so, what are situations when an angle or channel cross sections are preferred in structural work? Per unit mass is the rolling mill cost of an I beam higher?
For beams & columns would an I section always be preferred? Or not?
