**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Unequal leg hot-rolled angles to EN 10056-1: L 100x50x8 has legs of the sizes shown and a thickness t in mm. Each size has a root radius r1 and a toe radius r2 (about r1/2) printed in the standard's table.
- r1 and r2 are from Roymech's reproduction of the EN 10056-1 table (checked against British Steel's datasheet for 120 to 200 mm); the standard itself is paywalled. r2 is drawn on the inner corner at the end of each leg only; the drawn area matches the published area within 2 % on every drawn size, which confirms that placement.
- Files are 100 mm long extrusions along X with the heel at the origin: leg a along +y, leg b along +z.
- 17 of the 46 sizes have files; all sizes are in the table.
