Profile overview for PFC 180x75x20

The PFC 180x75x20 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 180 mm and a flange width (b) of 75 mm, supported by a 6 mm thick web and 10.5 mm thick flanges. With a cross-sectional area of 2590 mm² and a linear mass of 20.3 kg/m, the PFC 180x75x20 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 13700000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 176200 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 1464000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the PFC 180x75x20 provides a y-axis shear area (at strong bending axis) of 1575 mm² for web shear verification and a torsion constant of 73400 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 6920000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
