STEEL UNEQUAL ANGLES DIMENSIONS AND PROPERTIES (METRIC)
Metric steel unequal angles dimensions and section properties are given
in the following chart per EN 100561:2006 "Structural steel equal and unequal leg angles  Part 1: Dimensions" and Steel Designers' Manual.
EN 100561 standard defines requirements for nominal dimensions of metric hotrolled 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 crosssection 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.
