W30×124 vs W30×132
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W30×132 is the heavier section at 132 lb per foot, versus 124 for W30×124 (8 lb/ft more).
Both are nominally 30 in. deep.
W30×132 has the greater bending strength: section modulus Sx of 380 in³ versus 355, about 7% more.
