Profile overview for RHS 250x150/8

The RHS 250x150/8 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a hot finished section, it complies with EN 10210-2 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 rectangular/square hollow section is defined by a depth of 250 mm, a width of 150 mm, and a uniform wall thickness of 8 mm. With a cross-sectional area of 6075.327412 mm² and a linear mass of 47.69132019 kg/m, the RHS 250x150/8 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 51110000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 500600 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 22980000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the RHS 250x150/8 provides a y-axis shear area (at strong bending axis) of 2278.24778 mm² for web shear verification and a torsion constant of 50210000 mm⁴ for calculating rotational twist under eccentric loading.
