W30×211 vs W30×235
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W30×235 is the heavier section at 235 lb per foot, versus 211 for W30×211 (24 lb/ft more).
Both are nominally 30 in. deep.
W30×235 has the greater bending strength: section modulus Sx of 748 in³ versus 665, about 12% more.
