UPN 240 vs UPE 240
- UPE 240 is 9 % lighter than UPN 240 (30.2 vs 33.2 kg/m).
- UPN 240 has 0 % higher strong-axis stiffness Iy.
- UPE 240 has 25 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- UPN 240 has 3 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, UPE 240 is the more efficient bending section (Iy/G: 119 vs 108 cm⁴ per kg/m).
