Profile overview for HD 260x142

The HD 260x142 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 278 mm and a flange width (b) of 265 mm, supported by a 15.5 mm thick web and 26.5 mm thick flanges. With a cross-sectional area of 18030 mm² and a linear mass of 142 kg/m, the HD 260x142 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 243300000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 2015000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 82350000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HD 260x142 provides a y-axis shear area (at strong bending axis) of 14045 mm² for web shear verification and a torsion constant of 4073000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 1299000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
