Profile overview for W 360x200x72

The W 360x200x72 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a hot rolled section, it complies with ASTM A 6/A 6M 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 350 mm and a flange width (b) of 204 mm, supported by a 8.6 mm thick web and 15.1 mm thick flanges. With a cross-sectional area of 9100 mm² and a linear mass of 72 kg/m, the W 360x200x72 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 201000000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 1281000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 21390000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the W 360x200x72 provides a y-axis shear area (at strong bending axis) of 6160.8 mm² for web shear verification and a torsion constant of 600900 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 599000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
