W24×146 vs W27×146
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W24×146 and W27×146 both weigh 146 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W27×146 is the deeper section at a nominal 27 in., versus 24 in.
W27×146 has the greater bending strength: section modulus Sx of 414 in³ versus 371, about 12% more.
