IPE 160 vs IPN 160
- IPE 160 is 12 % lighter than IPN 160 (15.8 vs 17.9 kg/m).
- IPN 160 has 8 % higher strong-axis stiffness Iy.
- IPE 160 has 25 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- IPN 160 has 10 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, IPE 160 is the more efficient bending section (Iy/G: 55 vs 52 cm⁴ per kg/m).
