HEA 1000 vs HEB 1000
- HEA 1000 is 13 % lighter than HEB 1000 (272.3 vs 314.0 kg/m).
- HEB 1000 has 16 % higher strong-axis stiffness Iy.
- HEB 1000 has 16 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEB 1000 has 16 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, both are similarly efficient in bending (Iy/G ≈ 2 043 cm⁴ per kg/m).
