HLZ 1100D

The HLZ 1100D 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 1087.4 mm and a flange width (b) of 460 mm, supported by a 22 mm thick web and 37 mm thick flanges. With a cross-sectional area of 57750 mm² and a linear mass of 453 kg/m, the HLZ 1100D 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 11563000000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 24050000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 601500000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HLZ 1100D provides a y-axis shear area (at strong bending axis) of 34040 mm² for web shear verification and a torsion constant of 21310000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 165560000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
