Values are calculated with the Section Properties Calculator. They usually differ from published catalog values by about 0.5%, and by up to 1% in rare cases, mostly for small sections. See how the values are calculated.

About IPE beams

IPE is the standard European I-section with parallel flanges, rolled to EN 10365. The flanges are narrow relative to the depth, so the section performs best in strong-axis bending: floor beams, purlins and secondary members. The number in the designation is the nominal depth in millimetres — IPE 200 is 200 mm deep. For columns and heavily loaded beams, see the wider-flange HEA, HEB and HEM sections.

T-sections (½IPE) are IPE beams split along the web at mid-depth: each half keeps the full flange and has half the depth.

Notations

Symbols used in the IPE beam and T-section tables. Units are shown in the table headings.

Geometry and mass

Section: Profile designation from the catalog.
h: Overall section depth.
b: Flange width.
t_w: Web thickness.
t_f: Flange thickness.
r₁: Root radius at the web-to-flange junction.
A: Cross-sectional area.
P: Perimeter of the section's outer contour.
Mass: Calculated mass per metre, using a steel density of 7,850 kg/m³.
C_x, C_y: Centroid coordinates measured from the lower-left reference corner of the section outline; shown for T-sections.

Bending properties

I_x, I_y: Second moments of area about the centroidal x–x and y–y axes.
I_p: Polar second moment of area about the centroid, equal to I_x + I_y.
W_x: Elastic section modulus about the x–x axis. For T-sections, W_x(t) and W_x(b) refer to the top and bottom extreme fibres.
W_y: Elastic section modulus about the y–y axis.
i_x, i_y: Radii of gyration about the x–x and y–y axes, respectively: i = √(I/A).
S_x, S_y: First moments of one half of the section area about the centroidal x–x and y–y axes.

Plastic properties

W_pl,x, W_pl,y: Plastic section moduli about the plastic neutral axes for bending about x–x and y–y.
e_pl,x: Offset of the plastic neutral axis from the centroidal x–x axis; shown for T-sections.

In the mm view, table headings scale fourth-power properties by 10⁶ and cubic properties by 10³. The displayed multiplier applies to the values in that column.
