W30×132 vs W30×148
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W30×148 is the heavier section at 148 lb per foot, versus 132 for W30×132 (16 lb/ft more).
Both are nominally 30 in. deep.
W30×148 has the greater bending strength: section modulus Sx of 436 in³ versus 380, about 15% more.
