Profile overview for HD 260x225

The HD 260x225 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 309 mm and a flange width (b) of 271 mm, supported by a 24 mm thick web and 42 mm thick flanges. With a cross-sectional area of 28660 mm² and a linear mass of 225 kg/m, the HD 260x225 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 437500000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 3395000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 139700000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HD 260x225 provides a y-axis shear area (at strong bending axis) of 22764 mm² for web shear verification and a torsion constant of 15330000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 2482000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
