Profile overview for HD 400x1299

The HD 400x1299 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 600 mm and a flange width (b) of 476 mm, supported by a 100 mm thick web and 140 mm thick flanges. With a cross-sectional area of 165470 mm² and a linear mass of 1299 kg/m, the HD 400x1299 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 7549500000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 33260000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 2544100000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HD 400x1299 provides a y-axis shear area (at strong bending axis) of 133280 mm² for web shear verification and a torsion constant of 955200000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 133120000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
