W10×60 vs W18×60

A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.

W10×60 and W18×60 both weigh 60 lb per foot, so the choice comes down to depth and stiffness rather than weight.

W18×60 is the deeper section at a nominal 18 in., versus 10 in.

W18×60 has the greater bending strength: section modulus Sx of 108 in³ versus 66.7, about 62% more.
