W10×100 vs W10×112
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×112 is the heavier section at 112 lb per foot, versus 100 for W10×100 (12 lb/ft more).
Both are nominally 10 in. deep.
W10×112 has the greater bending strength: section modulus Sx of 126 in³ versus 112, about 13% more.
