Calculated properties
Flanges and web calculated using centroidal rectangle properties- This simplified model treats the flanges as equal and aligned. It is not an accurate general channel or offset Z-section solver.
Length inputs are converted to millimetres for calculations. Review the assumptions before using results in engineering work.
About this calculation
Enter the required dimensions and select the appropriate length unit. The calculator displays results based on the selected calculation and its stated assumptions.
Moment of inertia and related section properties depend on the geometry, reference axes, units, and assumptions used. Review the displayed formula and assumptions before using any result.
These tools are intended for educational and preliminary engineering calculations. Independently verify critical results before using them in engineering design or safety-related work.
