W12×152 vs W33×152
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W12×152 and W33×152 both weigh 152 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W33×152 is the deeper section at a nominal 33 in., versus 12 in.
W33×152 has the greater bending strength: section modulus Sx of 487 in³ versus 209, about 133% more.
