EN 10056-1-2017 pdf download.Structural steel equal and unequal leg angles – Part 1 Dimensions.
This EN 10056-1 specifies requirements for the nominal dimensions of hot-rolled equal and unequal leg angles. This European Standard does not apply to angles with square roots. These requirements do not apply to equal and unequal leg angles rolled from stainless steel.

3 Terms and definitions
For the purposes of this document, the definitions given in EN 10079 apply.
4 Designation
The designation of the hot-rolled equal and unequal leg angles shall comprise:
1) the number of this European Standard;
2) the letter L for angles;
3) the leg length a (in mm);
4) the leg length a orb (in mm);
Example of designation for an equal angle with leg length of a = 70 mm and leg thickness of 7 mm made from steel of grade S235JR (material number 1.0038) as specified in EN 10025-2:
EN 10056-1 — L 70 x 70 x 7 – EN 10025-2 — S235jR
or
EN 10056-1 — L 70 x 70 x 7— EN 10025-2 — 1.0038
Example of designation for an unequal angle with leg length of a = 50 mm and leg length b = 30 and leg thickness of 5 mm made from steel of grade S235JR (material number 1.0038) as specified In EN 10025-2:
EN 10056-1 — L 50 x 30 x 5— EN 10025-2 — S235JR
or
EN 10056-1 — L 50 x 30 x 5— EN 10025-2 — 1.0038
5 Dimensions
Dimensions of hot-rolled equal and unequal leg angles given in Table 1 and Table 2 and illustrated in Figure 1 and Figure 2 within this European standard are preferred dimensions. Other sizes may be ordered according to this standard, the corresponding dimensions shall be provided at the time of the order.
In the production of structural shapes, the dimensions and weights may vary slightly from the published nominal figures. However, they remain within the permissible tolerance.
Roll wear may also slightly affect the radii of fillets and rounded edges.
6 Tolerances on shape and dimensions
Tolerances on shape and dimensions shall be as given in EN 10056-2.
7 Material
Angles covered by this standard shall preferably be made of one of the steel grades specified in EN 10025-2 to EN 10025-5. Other steel grades as given in EN 10273, EN 10225 and EN 10028-2 may also be used for specific applications. The desired steel grade shall be specified at the time of ordering.EN 10056-1-2017 pdf download.
