IPE 200 vs IPN 200
- IPE 200 is 15 % lighter than IPN 200 (22.4 vs 26.2 kg/m).
- IPN 200 has 10 % higher strong-axis stiffness Iy.
- IPE 200 has 22 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- IPN 200 has 13 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, IPE 200 is the more efficient bending section (Iy/G: 87 vs 82 cm⁴ per kg/m).
