EN 1090-3

This guide focuses on choosing the publication and connecting it to a useful supplier evidence package, particularly where extrusions, welded assemblies and site installation come from different parties.

Published edition and revision status

The edition checked on 7 October 2026 is EN 1090-3:2019. Genorma lists it as published and records a “standard to be revised” stage. DIN Media lists DIN EN 1090-3:2019-07, the German adoption of that European edition, as current. A planned revision is not the same as withdrawal. Genorma record; DIN Media catalogue.

For a long project, give someone responsibility for checking later publications. Record the contract edition, the purchased document and the date of the status check. If a revision appears during procurement, ask the specifier how it affects the agreed work instead of automatically changing the order.

Check the aluminium scope before choosing a part

The published scope covers structural aluminium produced from several forms, including rolled products, extrusions, drawn products, forgings and castings. It addresses structures under static or fatigue loading and includes temporary aluminium structures. It points to relevant EN 1999 design parts and gives priority to EN 1090-5 where cold-formed profiled sheeting falls within that part’s scope. Source: Genorma scope.

The BSI series catalogue identifies the related parts. Use the EN 1090 family guide to organise the wider document set. Avoid assuming that the same part covers every metal item in a quotation.

What should be in an aluminium purchasing brief?

Start with the design and fabrication information the supplier will actually receive. Aluminium grade alone is a poor description of an order. The buyer should help the project team make its assumptions visible before manufacturing begins.

• Material identity: record the specified alloy, temper and product form, together with the drawing or specification that controls them. Ask who approves a substitution.
• Connection and assembly plan: distinguish factory-welded assemblies, mechanical connections, site work and supplied subassemblies. State which party is responsible for each interface.
• Project execution information: obtain the specified execution class and other project choices from the responsible designer or specifier. Do not derive them from the fact that a structure is aluminium or temporary.
• Surface and exposure assumptions: record the intended finish and service setting, and ask who coordinates these with other materials and treatments in the package.
• Delivery and evidence: agree component identification, drawing revisions, inspection records and the handover sequence before the goods arrive.

The DIN Media overview identifies manufacturing, joining, assembly, surface treatment, traceability and inspection among the standard’s subject areas. The list above is an original procurement aid; it does not prescribe the standard’s technical limits or acceptance criteria.

For repeat orders, compare the new brief with the previously approved one. A supplier may offer a different extrusion, alter a joint or move production to another location while retaining the same commercial product name. Ask the project’s responsible reviewer to decide whether those changes affect the agreed evidence. Keep that decision linked to the order.

A fictional example: a temporary event structure

An event contractor buys an aluminium truss assembly and cold-formed roof components from one supplier. The quotation refers to Part 3 and assumes that “temporary” makes the package straightforward.

The buyer asks for a component schedule rather than accepting one description for the whole package. The project team checks Part 3 for the truss and the Part 5 boundary for the roof components. The designer confirms the intended configuration and execution information; the supplier explains factory work, site assembly responsibilities and the evidence to accompany each delivery.

The purchasing decision is to obtain the documents needed for those separate reviews and revise the order description. No conformity conclusion follows from the catalogue titles alone. This is a fictional example, not a completed engineering or supplier assessment.

Keep execution, design and market access separate

Part 3 is not a replacement for the structural design. Nor does buying it produce a supplier certificate or automatically settle a CE-marking question. Construction-product obligations depend on the product and applicable route. The Commission’s CPR revision guidance describes transition by product family; check the relevant position for the actual order.

In practice, keep three fields in the procurement record: design basis, execution basis and conformity-assessment basis. Leaving one blank reveals an unresolved question that a generic “EN 1090” statement can hide.

Buy the publication the team needs

Match the edition, language and format to the project. A national adoption may have its own prefix and publication date; compare the stated European edition. If several people need access, confirm the licence with the seller under Genorma’s document-use terms.

The merchant confirms available options and the final checkout price.

Frequently asked questions

Is EN 1090-3:2019 withdrawn because a revision is planned?

Not according to the records checked for this guide. Genorma lists the document as published; DIN Media lists its adoption as current. Recheck status when placing the order.

Can I use the steel part for aluminium fabrication?

Do not treat Part 2 as an interchangeable aluminium execution document. Identify the material and applicable scope, then select the relevant parts for the package.

Does Part 3 cover every aluminium item?

No. Its scope is structural execution, with boundaries and related documents to check. Material alone does not establish that a decorative item, roof product or other component falls within it.

Is temporary aluminium construction outside the standard?

The public scope explicitly includes temporary aluminium structures. The actual project still needs its design conditions and execution information resolved.
