Profile overview for W 610x325x551

The W 610x325x551 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 711 mm and a flange width (b) of 347 mm, supported by a 38.6 mm thick web and 69.1 mm thick flanges. With a cross-sectional area of 70200 mm² and a linear mass of 551 kg/m, the W 610x325x551 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 5590700000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 18650000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 484100000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the W 610x325x551 provides a y-axis shear area (at strong bending axis) of 47955.4 mm² for web shear verification and a torsion constant of 85770000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 49560000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
