W24×94 vs W24×103
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W24×103 is the heavier section at 103 lb per foot, versus 94 for W24×94 (9 lb/ft more).
Both are nominally 24 in. deep.
W24×103 has the greater bending strength: section modulus Sx of 245 in³ versus 222, about 10% more.
