137 AISC v16.0 records
AISC Single-angle (L) shapes.
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.
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.

How to read the L records
An angle designation carries two leg sizes and thickness. In the single-angle database convention b is the longer leg and d the shorter leg; equal-leg records have matching values.
Identify the connected leg and heel orientation before using centroid or principal-axis values. Ix, Iy and Iz are distinct reference fields; swapping legs in a model does not relabel the source record automatically.
This dataset contains 137 L records, with nominal weights from 1.65 to 105 lb/ft and listed shorter leg d values from 1.5 to 12 in. These ranges describe the published records, not current supplier inventory or a selection recommendation.
Start with the exact designation, open its full record, then compare only the dimensions and properties relevant to your task. For example, L4X4X1/2 lists 12.8 lb/ft, 3.75 in² area, Ix = 5.52 in⁴ and Iy = 5.52 in⁴. The x and y labels retain the database axes; their values do not establish allowable loads.
The AISC v16.0 workbook Readme defines the variables and shape figures. This directory uses the US customary record; the comparison tool converts displayed units. Check the required edition and product specification before transferring data.
Worked quantity example
Nominal weight for L4X4X1/2
Assume 3 pieces, each 20 ft (6.096 m) long. This is a hypothetical quantity example, not a stock-length or lifting recommendation.
| Quantity | Calculation | Nominal pounds | Kilogram equivalent |
|---|---|---|---|
| One 20 ft piece | 20 ft × 12.8 lb/ft | 256 lb | 116.12 kg |
| 3 pieces | 3 × 256 lb | 768 lb | 348.359 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.
