IPE 300 vs IPN 300
- IPE 300 is 22 % lighter than IPN 300 (42.2 vs 54.2 kg/m).
- IPN 300 has 17 % higher strong-axis stiffness Iy.
- IPE 300 has 34 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- IPN 300 has 21 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, IPE 300 is the more efficient bending section (Iy/G: 198 vs 181 cm⁴ per kg/m).
