W12×50 vs W12×53
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W12×53 is the heavier section at 53 lb per foot, versus 50 for W12×50 (3 lb/ft more).
Both are nominally 12 in. deep.
W12×53 has the greater bending strength: section modulus Sx of 70.6 in³ versus 64.2, about 10% more.
