< back to Construction Products Regulation


From 1st July 2014, CE Marking of structural steel and aluminium work for use in construction, as specified in EN 1090, will become mandatory under the Construction Products Regulation.

The scope of EN 1090 is very broad, it includes:

  • Structural steel and aluminium components
  • Fabrications and kits of parts manufactured from steel and aluminium
  • Steel components used in composite steel and concrete structures

These are all intended for permanent use in buildings, bridges, highways and other civil engineering structures.

These components or structures can be made from hot rolled or cold formed materials or steel/alloy products produced with other technologies. They may be sections or profiles with various shapes, flat products (plates, sheet, strip), bars, castings, and forgings made of steel and aluminium materials. They may be unprotected or protected against corrosion by coating or other surface treatment, e.g. anodising of aluminium or galvanising of steels.

It does not cover components for suspended ceilings and rails or sleepers for use in railway systems.

EN 1090 consists of the following three sections:

  • Part 1: Requirements for conformity assessment of structural components. Details of all the individual requirements which must be achieved in order to CE mark. Different levels of stringency are given depending on the execution class.
  • Part 2: Technical requirements for steel structures
  • Part 3: Technical requirements for aluminium structures

Parts 2 and 3 support the application of Part 1 by providing the technical requirements relevant to the manufacture of steel and aluminium components respectively.

In relation to CE Marking, the relevant clauses of the standard are:

  • Scope
  • Normative references
  • Terms and definitions
  • Specifications and documentation
  • Constituent products
  • Preparation and assembly
  • Welding
    Mechanical fastening
  • Erection
  • Surface treatment
  • Geometrical tolerances
  • Inspection, testing and correction.

If all you do is to make components following your customers’ specification, you are not required to demonstrate that the design of the component is adequate, merely that you can reliably manufacture the item as specified. For more details please see the following section “Component Specification”.
