W14×43 vs W14×48
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W14×48 is the heavier section at 48 lb per foot, versus 43 for W14×43 (5 lb/ft more).
Both are nominally 14 in. deep.
W14×48 has the greater bending strength: section modulus Sx of 70.2 in³ versus 62.6, about 12% more.
