W12×26 vs W12×30
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W12×30 is the heavier section at 30 lb per foot, versus 26 for W12×26 (4 lb/ft more).
Both are nominally 12 in. deep.
W12×30 has the greater bending strength: section modulus Sx of 38.6 in³ versus 33.4, about 16% more.
