Steel Section Database (IPE)
Free IPE steel beam properties table (EN 10365): dimensions, area, moment of inertia, section modulus, radius of gyration and mass. Filter by depth and find the lightest section.
What is this steel section database?
This is a quick reference for the geometric properties of European IPE hot-rolled steel I-beams, as standardised in EN 10365. For every size it lists the nominal dimensions (depth, width, web and flange thickness), the cross-sectional area, the second moments of area about both axes (Iₓ strong, I_y weak), the elastic section moduli (Wₓ, W_y), the radii of gyration (rₓ, r_y) and the mass per metre. The section moduli, radii of gyration and mass are derived exactly from the catalog area and moments, so the values agree with published tables to within rounding. Use it to pick a beam: filter by the depth you can fit, or enter the section modulus your bending check requires and the table highlights the lightest section that satisfies it.
How to use it
- Browse the table — every IPE size from IPE 80 to IPE 600 with its key properties.
- Set a maximum depth to keep only sections that fit your structure.
- Enter the required section modulus Wₓ (from your bending stress check) to highlight the lightest adequate beam.
- Click any row to see the full property card and the section diagram.
Properties listed
- Mass — Weight per metre (kg/m) — proportional to cost.
- h, b — Overall depth and flange width.
- A — Cross-sectional area.
- Iₓ, I_y — Second moments of area about the strong (x) and weak (y) axes.
- Wₓ, W_y — Elastic section moduli, I / extreme-fibre distance — used for bending stress.
- rₓ, r_y — Radii of gyration, √(I/A) — used for column buckling.
Data follows EN 10365 (IPE series). Section moduli, radii of gyration and mass (steel density 7850 kg/m³) are derived from the catalog area and second moments. This is a reference aid, not a substitute for a verified design code check.
