Profile overview for HL 920x390

The HL 920x390 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 936 mm and a flange width (b) of 420 mm, supported by a 21.3 mm thick web and 36.6 mm thick flanges. With a cross-sectional area of 49430 mm² and a linear mass of 390 kg/m, the HL 920x390 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 7458100000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 18010000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 452700000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HL 920x390 provides a y-axis shear area (at strong bending axis) of 30744 mm² for web shear verification and a torsion constant of 17410000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 91390000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
