Angles · Size & tolerance table

Equal and unequal angles (EN 10056-1, formerly DIN 1028 and DIN 1029)

Standard: EN 10056-1 (dimensions) · EN 10056-2 (tolerances) formerly DIN 1028 (equal angles), DIN 1029 (unequal angles), BS 4848-4

Angles are designated leg × leg × thickness in millimetres — L 50 × 50 × 5, or L 120 × 80 × 8 for an unequal angle with the long leg first. EN 10056-1 lists the sizes and EN 10056-2 the tolerances; it replaced the German DIN 1028 and DIN 1029 and the British BS 4848-4.

An angle bends about its own principal axes u-u and v-v, which are inclined to the legs; the v-v axis is the weakest and governs a single angle used as a strut. The small equal angles up to 90 × 90 are the sizes of the former DIN 1028; a few of them (55 × 55, 70 × 70 × 6, 30 × 30 × 5) were non-preferred there and are less often rolled.

Equal angle cross-section with leg a, thickness s (t), radii r1 and r2, centroid distance e and the principal axes u (ξ) and v (η)

Equal angles — 20 × 20 to 200 × 200
