IPE 500 vs HEA 500
- IPE 500 is 42 % lighter than HEA 500 (90.7 vs 155.1 kg/m).
- HEA 500 has 80 % higher strong-axis stiffness Iy.
- HEA 500 has 4.8× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEA 500 has 80 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, HEA 500 is the more efficient bending section (Iy/G: 561 vs 531 cm⁴ per kg/m).
