W24×94 vs W27×94
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W24×94 and W27×94 both weigh 94 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W27×94 is the deeper section at a nominal 27 in., versus 24 in.
W27×94 has the greater bending strength: section modulus Sx of 243 in³ versus 222, about 9% more.
