Using this section record

Read the axis labels before using inertia or modulus: the major and minor axes are not interchangeable. Dimensions are in millimetres; area is in cm², second moments in cm⁴, moduli in cm³ and radii in cm. Convert powers of length consistently when transferring values to a calculation.

A Source line covers only its listed verified fields. Other fields remain subject to verification. A dash is unavailable, never zero. Withheld values must not be inferred from the remaining dimensions. Nominal mass and dimensions are reference values rather than measured tolerances or procurement guarantees. Confirm the exact product, manufacturing route, grade and thickness with the manufacturer. Section properties alone do not establish member resistance: stability, effective length, connections and project design requirements need separate assessment.
