Steel Section Database

Free steel section tables: IPE, HEA, HEB (EN 10365) and AISC W-shapes — dimensions, moment of inertia, section modulus, radius of gyration, weight.

Look up steel I-beam section properties: European IPE, HEA and HEB (EN 10365, metric) and American W-shapes (AISC v15, imperial) — dimensions, area, moments of inertia, section moduli, radii of gyration and weight. Filter by maximum depth, or enter a required section modulus to find the lightest adequate beam. Click any row for the full property card and section diagram.

What is this steel section database?

This is a quick reference for the geometric properties of hot-rolled steel I-beams: the European IPE, HEA and HEB series (EN 10365, metric units) and the American W-shape series (AISC Shapes Database v15.0, imperial units). 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

  1. Browse the table — every IPE size from IPE 80 to IPE 600 with its key properties.
  2. Set a maximum depth to keep only sections that fit your structure.
  3. Enter the required section modulus Wₓ (from your bending stress check) to highlight the lightest adequate beam.
  4. 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/HEA/HEB) and the AISC Shapes Database v15.0 (W-shapes). Section moduli, radii of gyration and mass (steel density 7850 kg/m³ / 490 lb/ft³) are derived from the catalog area and second moments. This is a reference aid, not a substitute for a verified design code check.

Frequently Asked Questions

IPE is the European series of hot-rolled I-beams (I-Profil Européen) with parallel flanges, standardised in EN 10365. Sizes are named by their nominal depth in millimetres — IPE 300 is 300 mm deep.

From your bending check you need a section modulus W ≥ M / σ_allow. Enter that required Wₓ and the table highlights the lightest IPE that meets it — the lightest section is usually the cheapest. Also check deflection (using Iₓ) and any depth limit.

Yes. The dimensions, area and moments of inertia follow EN 10365; the section moduli, radii of gyration and mass are derived exactly from them and match published property tables to rounding.

Yes — click a section and use its Iₓ (also shown in mm⁴) in the Beam Analysis calculator to get deflections, or compare with a custom shape in the Cross-Section Properties calculator.

This first release covers the full IPE series (IPE 80–600). HEA/HEB and American W-shapes are planned next.
