Profile overview for UC 203x203x100

The UC 203x203x100 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 229 mm and a flange width (b) of 210 mm, supported by a 14.5 mm thick web and 23.7 mm thick flanges. With a cross-sectional area of 12670 mm² and a linear mass of 100 kg/m, the UC 203x203x100 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 113200000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 1148000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 36630000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UC 203x203x100 provides a y-axis shear area (at strong bending axis) of 9954 mm² for web shear verification and a torsion constant of 2089000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 385400000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
