W8×67 vs W16×67
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W8×67 and W16×67 both weigh 67 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W16×67 is the deeper section at a nominal 16 in., versus 8 in.
W16×67 has the greater bending strength: section modulus Sx of 117 in³ versus 60.4, about 94% more.
