W12×53 vs W12×58
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W12×58 is the heavier section at 58 lb per foot, versus 53 for W12×53 (5 lb/ft more).
Both are nominally 12 in. deep.
W12×58 has the greater bending strength: section modulus Sx of 78 in³ versus 70.6, about 10% more.
