UPN 200 vs UPE 200
- UPE 200 is 10 % lighter than UPN 200 (22.8 vs 25.3 kg/m).
- UPN 200 has 0 % higher strong-axis stiffness Iy.
- UPE 200 has 27 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- UPN 200 has 4 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, UPE 200 is the more efficient bending section (Iy/G: 84 vs 75 cm⁴ per kg/m).
