# STEEL ANGLES WITH EQUAL LEGS ("L" SHAPES)

"Steel Angles with Equal Legs Calculator" has been developed to show basic dimensions and section properties of steel angles with equal legs.

The designation of the steel angles (also known as L Shapes) gives information about the width of each leg and thickness. For example L 3 × 3 × 1⁄4 means a 3 × 3-inch angle of 1⁄4-inch thickness. Angles are often used as tension members of trusses and towers, framing members for machine structures, brackets.

The following dimensional and property information for steel angles with equal legs is given in Steel Construction Manual for the angles covered in ASTM A 6/A 6M standard.  Section properties data are given for the X axis and Y axis. Additional data are given for the Z axis, which is defined as the axis having the smallest value of radius of gyration. The column tends to buckle about the Z-axis.

### 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.

Workable Gages: The transverse center-to-center spacing of fasteners. Use g value for one fastener and g1 and g2 for 2 fasteners.
