Metric Steel Equal Angle Section Properties (EN 10056-1)

Calculator for geometric section properties of hot-rolled metric steel equal leg angles according to EN 10056-1. Suitable for structural engineers, designers and students.

This calculator provides the following section properties:

  • Mass per unit length
  • Cross-sectional area
  • Leg length, thickness and root radius
  • Area moments of inertia about principal axes
  • Elastic section moduli
  • Radii of gyration

Dimensions and property values are based on EN 10056-1:2006 – Structural Steel Equal and Unequal Leg Angles – Part 1: Dimensions. The standard does not apply to angles rolled from stainless steel.

Input parameters

1. Select angle size and thickness   →   2. Click Calculate
Standard equal angle designations (leg × leg) in millimetres.
Available thickness values for the selected leg length.

Note: Use a dot “.” as decimal separator.
