Structural steel equal and unequal leg angles - Part 1: Dimensions

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.

Gleichschenklige und ungleichschenklige Winkel aus Stahl - Teil 1: Maße

Diese Europäische Norm legt die Anforderungen an die Nennmaße von warmgewalzten gleichschenkligen und ungleichschenkligen Winkeln fest. Diese Europäische Norm gilt nicht für scharfkantige Winkel. Diese Europäische Norm gilt nicht für gewalzte gleichschenklige und ungleichschenklige Winkel aus nichtrostendem Stahl.

Cornières à ailes égales et inégales en acier de construction - Partie 1: Dimensions

La présente norme européenne spécifie les exigences relatives aux dimensions nominales des cornières laminées à chaud à ailes égales et à ailes inégales. La présente norme européenne ne s'applique pas aux cornières présentant un raccordement des ailes à angle vif. Ces prescriptions ne s'appliquent pas aux cornières à ailes égales et à ailes inégales laminées en acier inoxydable.

Kotni (L) jekleni profili z enakimi in različnimi kraki - 1. del: Mere

Ta evropski standard določa zahteve za nazivne mere vroče valjanih kotnih profilov z enakimi in različnimi kraki. Ta evropski standard se ne uporablja za kotne profile s kvadratnimi koreni. Te zahteve se ne uporabljajo za enake in različne krake valjanih kotnih profilov iz nerjavnega jekla.

Overview

EN 10056-1:2017 is a CEN European Standard that defines the nominal dimensions of hot-rolled structural steel angles - both equal leg angles and unequal leg angles. It establishes preferred sizes, designation rules and general dimensional guidance for hot-rolled angles used in structural steelwork. The standard specifically excludes angles with square roots and does not apply to angles rolled from stainless steel.

Keywords: EN 10056-1:2017, structural steel angles, equal leg angles, unequal leg angles, hot-rolled angles, CEN standard, dimensions

Key Topics

• Scope and exclusions
  • Applies to hot-rolled equal and unequal leg angles for structural use.
  • Does not cover angles with square roots or stainless-steel angles.
• Designation rules
  • The designation comprises: standard number, letter L (for angles), leg lengths (a and b), thickness (t), reference to the material standard and steel grade (or steel number).
  • Example: EN 10056-1 - L 70 × 70 × 7 – EN 10025-2 - S235JR
• Preferred dimensions and sectional properties
  • Tables (Table 1 and Table 2) list preferred nominal dimensions and sectional properties (mass, sectional area, centre of gravity, moments of inertia, section modulus).
  • These published figures are nominal; actual production dimensions may vary slightly within permissible tolerances.
• Tolerances and shape
  • Tolerances on shape and dimensions are not given here but are specified in EN 10056-2 (Part 2).
• Material guidance
  • Angles are preferably made from steel grades referenced in EN 10025‑2 to EN 10025‑5. Other steel grades (EN 10273, EN 10225, EN 10028‑2) may be used when specified.

Applications

EN 10056-1:2017 is practical for:

• Structural design and detailing of frames, trusses, bracing and connections where standard hot‑rolled angles are used.
• Fabrication shops and steel producers for specifying nominal sizes and ordering.
• Procurement teams and project specifications to unambiguously identify angle sections and material standards.
• Inspectors and quality assurance to verify that delivered angles match ordered designation and nominal dimensions.

Who should use it

• Structural engineers and detailers
• Steel fabricators and roll-forming mills
• Spec writers, procurement officers and project managers
• CE/national standards bodies and conformity assessors

Related Standards

• EN 10056-2 - Tolerances on shape and dimensions (companion document)
• EN 10025‑2 to EN 10025‑5 - Technical delivery conditions for structural steels
• EN 10079 - Definition of steel products
• EN 10273, EN 10225, EN 10028‑2 - Other steels referenced for specific applications
• EN 1993‑1‑1 - Eurocode 3 (symbols comparison provided in Annex A)

Use EN 10056-1:2017 when you need consistent, CEN-approved nominal dimensions and designation rules for hot-rolled structural steel angles used in building and civil engineering projects.
