Profile overview for HEC 300

The HEC 300 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 320 mm and a flange width (b) of 305 mm, supported by a 16 mm thick web and 29 mm thick flanges. With a cross-sectional area of 22510 mm² and a linear mass of 177 kg/m, the HEC 300 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 409500000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 2926000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 137300000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HEC 300 provides a y-axis shear area (at strong bending axis) of 17690 mm² for web shear verification and a torsion constant of 6040000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 2903000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
