Profile overview for HE 800x444

The HE 800x444 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 842 mm and a flange width (b) of 313 mm, supported by a 30 mm thick web and 54 mm thick flanges. With a cross-sectional area of 56600 mm² and a linear mass of 444 kg/m, the HE 800x444 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 (I_y) of 6344700000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 17630000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 278000000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HE 800x444 provides a y-axis shear area (at strong bending axis) of 33804 mm² for web shear verification and a torsion constant of 41540000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 42840000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
