W10×15 vs W10×17
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×17 is the heavier section at 17 lb per foot, versus 15 for W10×15 (2 lb/ft more).
Both are nominally 10 in. deep.
W10×17 has the greater bending strength: section modulus Sx of 16.2 in³ versus 13.8, about 17% more.
