European foreword

This document (EN 10056-1:2017) has been prepared by Technical Committee ECISS/TC 103

“Structural steels other than reinforcements”, the secretariat of which is held by DIN.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2017, and conflicting national standards shall be withdrawn at the latest by July 2017.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 10056-1:1998.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

1 Scope

This European Standard 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.

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 10025-2, Hot rolled products of structural steels - Part 2: Technical delivery conditions for non-alloy structural steels

EN 10025-3, Hot rolled products of structural steels - Part 3: Technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels

EN 10025-4, Hot rolled products of structural steels - Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels

EN 10025-5, Hot rolled products of structural steels - Part 5: Technical delivery conditions for structural steels with improved atmospheric corrosion resistance

EN 10056-2, Structural steel equal and unequal leg angles - Part 2: Tolerances on shape and dimensions EN 10079, Definition of steel products

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 or b (in mm);

5) the leg thickness t (in mm);

6) reference to the material standard;

7) steel name or steel number.

5 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 × 70 × 7 – EN 10025-2 — S235JR or

EN 10056-1 — L 70 × 70 × 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 × 30 × 5 – EN 10025-2 — S235JR or

EN 10056-1 — L 50 × 30 × 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.
