W10×26 vs W10×30
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×30 is the heavier section at 30 lb per foot, versus 26 for W10×26 (4 lb/ft more).
Both are nominally 10 in. deep.
W10×30 has the greater bending strength: section modulus Sx of 32.4 in³ versus 27.9, about 16% more.
