Section properties

Area, centroid, second moment of area, section modulus and radius of gyration for rectangles, circles, pipes, I-beams, tees and channels.

The I-beam starts as an IPE 300, so you can compare with the steel tables (A = 53.8 cm², Iy = 8356 cm⁴). Hollow sections and channels are modelled with sharp corners, so table values for rolled sections may differ slightly.
