Unequal angles (EN 10056-1): L 100x50x8, L 150x100x10, L 30x20x3 to L 200x150x15 dimensions + STEP/STL — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/en-10056-unequal-angles/ (sheet CC BY 4.0) Basis: EN 10056-1 table values (r1, r2, t, area) as reproduced by Roymech and British Steel Catalog version: 2026-10-20 Overall (mm): length 100.0 - 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. size (mm) mass (kg/m) leg a (mm) leg b (mm) t (mm) r1 (mm) r2 (mm) area (cm2) 200x150x15 39.6 200.0 150.0 15.0 15.0 7.5 50.5 200x150x12 32.0 200.0 150.0 12.0 15.0 7.5 40.8 200x100x15 33.7 200.0 100.0 15.0 15.0 7.5 43.0 200x100x12 27.3 200.0 100.0 12.0 15.0 7.5 34.8 200x100x10 23.0 200.0 100.0 10.0 15.0 7.5 29.2 150x100x12 22.5 150.0 100.0 12.0 12.0 6.0 28.7 150x100x10 19.0 150.0 100.0 10.0 12.0 6.0 24.2 150x90x15 26.6 150.0 90.0 15.0 12.0 6.0 33.9 150x90x12 21.6 150.0 90.0 12.0 12.0 6.0 27.5 150x90x10 18.2 150.0 90.0 10.0 12.0 6.0 23.2 150x75x15 24.8 150.0 75.0 15.0 11.0 5.5 31.6 150x75x12 20.2 150.0 75.0 12.0 11.0 5.5 25.7 150x75x10 17.0 150.0 75.0 10.0 11.0 5.5 21.6 150x75x9 15.4 150.0 75.0 9.0 12.0 6.0 19.6 135x65x10 15.0 135.0 65.0 10.0 11.0 5.5 19.1 135x65x8 12.2 135.0 65.0 8.0 11.0 5.5 15.5 125x75x12 17.8 125.0 75.0 12.0 11.0 5.5 22.7 125x75x10 15.0 125.0 75.0 10.0 11.0 5.5 19.1 125x75x8 12.2 125.0 75.0 8.0 11.0 5.5 15.5 120x80x12 17.8 120.0 80.0 12.0 11.0 5.5 22.7 120x80x10 15.0 120.0 80.0 10.0 11.0 5.5 19.1 120x80x8 12.2 120.0 80.0 8.0 11.0 5.5 15.5 100x75x12 15.4 100.0 75.0 12.0 10.0 5.0 19.7 100x75x10 13.0 100.0 75.0 10.0 10.0 5.0 16.6 100x75x8 10.6 100.0 75.0 8.0 10.0 5.0 13.5 100x65x10 12.3 100.0 65.0 10.0 10.0 5.0 15.6 100x65x8 9.94 100.0 65.0 8.0 10.0 5.0 12.7 100x65x7 8.77 100.0 65.0 7.0 10.0 5.0 11.2 100x50x8 8.97 100.0 50.0 8.0 8.0 4.0 11.4 100x50x6 6.84 100.0 50.0 6.0 8.0 4.0 8.71 80x60x7 7.36 80.0 60.0 7.0 8.0 4.0 9.38 80x40x8 7.07 80.0 40.0 8.0 7.0 3.5 9.01 80x40x6 5.41 80.0 40.0 6.0 7.0 3.5 6.89 75x50x8 7.39 75.0 50.0 8.0 7.0 3.5 9.41 75x50x6 5.65 75.0 50.0 6.0 7.0 3.5 7.19 70x50x6 5.41 70.0 50.0 6.0 7.0 3.5 6.89 65x50x5 4.35 65.0 50.0 5.0 6.0 3.0 5.54 60x40x6 4.46 60.0 40.0 6.0 6.0 3.0 5.68 60x40x5 3.76 60.0 40.0 5.0 6.0 3.0 4.79 60x30x5 3.37 60.0 30.0 5.0 6.0 3.0 4.29 50x30x5 2.96 50.0 30.0 5.0 5.0 2.5 3.78 45x30x4 2.25 45.0 30.0 4.0 4.5 2.25 2.86 40x25x4 1.93 40.0 25.0 4.0 4.0 2.0 2.46 40x20x4 1.77 40.0 20.0 4.0 4.0 2.0 2.26 30x20x4 1.46 30.0 20.0 4.0 4.0 2.0 1.86 30x20x3 1.12 30.0 20.0 3.0 4.0 2.0 1.43 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Roymech: Unequal leg angles to EN 10056-1: size, r1, r2, mass, area — web — Publisher's page; dimensions are facts — https://roymech.org/Useful_Tables/Sections/U_AngleA_dim_prop.html Free files (CC BY 4.0, Xem Studio; STEP + STL, 17 parts): https://xemstudio.com/files/hardware/en-10056-unequal-angles/index.json API: https://xemstudio.com/api/geometry?object=en-10056-unequal-angles
