IPE 240 vs IPN 240
- IPE 240 is 15 % lighter than IPN 240 (30.7 vs 36.2 kg/m).
- IPN 240 has 9 % higher strong-axis stiffness Iy.
- IPE 240 has 28 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- IPN 240 has 12 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, IPE 240 is the more efficient bending section (Iy/G: 127 vs 117 cm⁴ per kg/m).
