UPN 160 vs UPE 160
- UPE 160 is 10 % lighter than UPN 160 (17.0 vs 18.8 kg/m).
- UPN 160 has 2 % higher strong-axis stiffness Iy.
- UPE 160 has 25 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- UPN 160 has 5 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, UPE 160 is the more efficient bending section (Iy/G: 54 vs 49 cm⁴ per kg/m).
