STEEL UNEQUAL ANGLES DIMENSIONS AND PROPERTIES (METRIC)

Metric steel unequal angles dimensions and section properties are given in the following chart per EN 10056-1:2006 "Structural steel equal and unequal leg angles - Part 1: Dimensions" and Steel Designers' Manual.

EN 10056-1 standard defines requirements for nominal dimensions of metric hot-rolled equal and unequal leg angles. This standard does not apply unequal angles rolled from stainless steel.

Dimensions, second moment of area, elastic section modulus and radius of gyration values are given by the following calculator for the selected steel unequal angle size.

Definitions:

Second Moment of Area: The capacity of a cross-section to resist bending.

Radius of Gyration (Area): The distance from an axis at which the area of a body may be assumed to be concentrated and the second moment area of this configuration equal to the second moment area of the actual body about the same axis.
