Profile overview for HEAA 300

The HEAA 300 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a hot rolled section, it complies with EN 10365 dimensional standards, ensuring predictability in detailing and fabrication.Access to its exact geometric and statical properties is essential for 3D modeling and structural verification.

Geometry: This open profile features a total depth (h) of 283 mm and a flange width (b) of 300 mm, supported by a 7.5 mm thick web and 10.5 mm thick flanges. With a cross-sectional area of 8890 mm² and a linear mass of 69.8 kg/m, the HEAA 300 offers a distinct stiffness-to-weight ratio for both column (axial) and beam applications.

Section properties: For design of bending, the major and minor axis properties dictate the member's structural capacity. The strong-axis moment of inertia (Iy) of 138000000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 1065000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 47330000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HEAA 300 provides a y-axis shear area (at strong bending axis) of 6300 mm² for web shear verification and a torsion constant of 478000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 877100000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
