IPE 140 vs IPN 140
- IPE 140 is 10 % lighter than IPN 140 (12.9 vs 14.3 kg/m).
- IPN 140 has 6 % higher strong-axis stiffness Iy.
- IPE 140 has 28 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- IPN 140 has 8 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, IPE 140 is the more efficient bending section (Iy/G: 42 vs 40 cm⁴ per kg/m).
