HEA 500 vs HEB 500
- HEA 500 is 17 % lighter than HEB 500 (155.1 vs 187.3 kg/m).
- HEB 500 has 23 % higher strong-axis stiffness Iy.
- HEB 500 has 22 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEB 500 has 22 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, both are similarly efficient in bending (Iy/G ≈ 567 cm⁴ per kg/m).
