About Equal Angles (EA)

Equal Angles (EAs) have two legs of equal length meeting at 90 degrees. They are used for bracing members, framing angles, lintels, and general fabrication. The principal axes of equal angles are at 45 degrees to the legs. Available from 20x20 to 250x250 in various thicknesses.

This page shows section properties for all 66 standard UK equal angles (ea) from the Tata Steel Blue Book (SCI P363). Properties include dimensions, cross-sectional area, second moment of area, elastic and plastic section modulus, radius of gyration, and torsional properties. All values are per BS 4-1:2005 / BS EN 10365.
