IPE 100 vs IPN 100
- IPE 100 is 2 % lighter than IPN 100 (8.1 vs 8.3 kg/m).
- IPN 100 has 0 % higher strong-axis stiffness Iy.
- IPE 100 has 30 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- IPN 100 has 1 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, both are similarly efficient in bending (Iy/G ≈ 21 cm⁴ per kg/m).
