UPN 100 vs UPE 100
- UPE 100 is 8 % lighter than UPN 100 (9.8 vs 10.6 kg/m).
- UPE 100 has 0 % higher strong-axis stiffness Iy.
- UPE 100 has 31 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- UPN 100 has 2 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, UPE 100 is the more efficient bending section (Iy/G: 21 vs 19 cm⁴ per kg/m).
