W10×49 vs W10×54
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×54 is the heavier section at 54 lb per foot, versus 49 for W10×49 (5 lb/ft more).
Both are nominally 10 in. deep.
W10×54 has the greater bending strength: section modulus Sx of 60 in³ versus 54.6, about 10% more.
