From designation to geometry

Reading the L6X6X5/16 record

This equal-leg angle has a longer leg b = 6 in, shorter leg d = 6 in and thickness t = 0.313 in in the database convention. Match the leg orientation to the source figure before locating a connection.

The centroid distances are x = 1.6 in and y = 1.6 in. The listed z-axis inertia Iz = 5.2 in⁴ is separate from Ix and Iy; an angle's principal axes should not be inferred from the edges of its outline.

Ix = 13 in⁴ and Iy = 13 in⁴ refer to the database x- and y-axes. The two listed values are equal. Axis letters are labels, not a guarantee that x is always the larger axis. These are geometric properties, not allowable loads or complete member capacities.

Match the axis and dimension conventions to the figures in the AISC v16.0 workbook Readme. The profile above simplifies manufacturing geometry; its outline is not used to recalculate the published properties.

Worked quantity example

Nominal weight for L6X6X5/16

Assume 3 pieces, each 20 ft (6.096 m) long. This is a hypothetical quantity example, not a stock-length or lifting recommendation.

Using the published 12.4 lb/ft weight
Quantity	Calculation	Nominal pounds	Kilogram equivalent
One 20 ft piece	20 ft × 12.4 lb/ft	248 lb	112.491 kg
3 pieces	3 × 248 lb	744 lb	337.473 kg

Conversion: 1 lb = 0.45359237 kg; displayed results are rounded. This multiplication excludes connection plates, bolts, weld metal, coatings, cutting allowances and actual material variation. Use the material takeoff for your own lengths and quantities.

Shape family context

What is a single angle?

An L-shape is a hot-rolled angle with two perpendicular legs, which may be equal or unequal. Its unsymmetric geometry makes orientation and principal-axis behavior important in both design and detailing.

Common context

Common project roles include bracing, lintels, shelf angles, edge framing, connection material, truss components, and miscellaneous support framing.

Detailing watch

Confirm which leg is outstanding, the heel and toe orientation, gage lines, eccentricity, leg clearance, fillet geometry, and whether the long or short leg connects.

Compare published reference values

L6X6X5/16 alongside nearby L records

These records share the same nominal series, outside envelope or leg arrangement, depending on the family. Peers are ordered by absolute weight difference, then listed depth and designation. The table does not rank structural performance or approve a substitution.

US customary values from the same AISC v16.0 dataset
Record	Weight (lb/ft)	Shorter leg d (in)	Area (in²)	Ix (in⁴)	Iy (in⁴)
L6X6X5/16 (this record)	12.4	6	3.67	13	13
L6X6X3/8	14.9	6	4.38	15.4	15.4
L6X6X7/16	17.2	6	5.08	17.6	17.6

Relative to L6X6X5/16, L6X6X3/8 changes nominal weight by +2.5 lb/ft, listed shorter leg d by 0 in, and area by +0.71 in². At the same hypothetical 20 ft length, the nominal weight difference is +50 lb.

Reference use only.

Data is derived from the AISC Shapes Database v16.0, consistent with the AISC Steel Construction Manual, 16th Edition, 1st Printing. AISC advises professional verification before use in a specific application. The downloadable DXF is a nominal reference profile and may simplify rolled fillets, flange tapers, angle radii, HSS corner radii, and other manufacturing geometry. Verify all dimensions and suitability before design, detailing, ordering, or fabrication.
