NOTE 1   The execution of structural components is referred to as manufacturing, in accordance with EN 1090-1.
This document specifies requirements independent of the type and shape of the aluminium structure, and this document is applicable to structures under predominantly static loads as well as structures subject to fatigue. It specifies requirements related to the execution classes that are linked with consequence classes.
NOTE 2   Consequence classes are defined in EN 1990.
NOTE 3   Recommendations for selection of execution class in relation to consequence class are given in EN 1999-1-1.
This document covers components made of constituent products with thickness not less than 0,6 mm for welded components not less than 1,5 mm.
For components made from cold formed profiled sheeting that are within the scope of EN 1090-5, the requirements of EN 1090-5 take precedence over corresponding requirements in this document.
This document applies to structures designed according to the relevant parts of EN 1999.

Overview - EN 1090-3:2019 (Execution of aluminium structures)

EN 1090-3:2019 specifies the technical requirements for execution of aluminium structural components and complete aluminium structures. It applies to structures and components manufactured from rolled sheet, strip and plate; extrusions; cold drawn rod, bar and tube; forgings; and castings. The standard covers both predominantly static and fatigue-loaded structures, including temporary aluminium structures. Thickness limits in the scope: constituent products from 0.6 mm and welded components not less than 1.5 mm.

This part of EN 1090 is focused on execution (manufacturing, preparation, assembly, erection, surface treatment) and is intended to be used with structure design rules given in EN 1999 (Eurocode 9). It also links execution classes to consequence classes (EN 1990) and provides options to match project-specific requirements.

Key technical topics and requirements

• Execution specification and documentation: required execution classes, tolerance types, quality documentation, and execution documentation (including quality plans and welding plans).
• Constituent products and traceability: identification, inspection documents, parent material requirements, welding consumables, mechanical fasteners and adhesives.
• Preparation: handling, storage, cutting, forming, drilling/holing, full-contact bearing surfaces, heat treatment and straightening.
• Welding: welding plans, specified processes (including friction stir welding), qualification of welding procedures and personnel, preheat/interpass, acceptance criteria and post-weld heat treatment.
• Mechanical fastening & adhesive bonding: bolting assemblies (preloaded and non-preloaded), rivets, screws, fit-up, slip-resistant joint preparation and tightening requirements.
• Erection: site conditions, erection method statements, supports, alignment and grouting, site surveys and protection/cleaning after erection.
• Surface treatment: surface preparation for protective finishes and guidance for application (informative annex).
• Testing, inspection and acceptance: acceptance criteria for welds and assemblies, marking and traceability throughout manufacturing and erection.

Practical applications - who uses this standard

• Aluminium fabricators and manufacturers seeking compliant production and CE marking support.
• Structural engineers and designers using EN 1999 who need execution guidance tied to design consequence classes.
• Contractors and erectors responsible for site erection, alignment and protection of aluminium structures.
• Quality managers and inspectors performing welding qualification, material traceability and acceptance testing.
• Specifiers and clients defining project-specific execution classes, tolerances and surface treatment requirements.

Related standards

• EN 1999 (Eurocode 9) - design of aluminium structures
• EN 1990 - basis of structural design (consequence classes)
• EN 1090-1 - execution requirements and CE marking for steel and aluminium structures
• EN 1090-5 - cold-formed profiled sheeting (takes precedence where applicable)

This document specifies requirements independent of the type and shape of the aluminium structure,
and this document is applicable to structures under predominantly static loads as well as structures
subject to fatigue. It specifies requirements related to the execution classes that are linked with
consequence classes.
NOTE 2 Consequence classes are defined in EN 1990.
NOTE 3 Recommendations for selection of execution class in relation to consequence class are given in
EN 1999-1-1.
This document covers components made of constituent products with thickness not less than 0,6 mm
for welded components not less than 1,5 mm.
For components made from cold formed profiled sheeting that are within the scope of EN 1090-5, the
requirements of EN 1090-5 take precedence over corresponding requirements in this document.
This document applies to structures designed according to the relevant parts of EN 1999. If this
document is used for structures designed according to other design rules or used for other alloys and
tempers not covered by EN 1999, a judgement of the reliability elements in these design rules is
intended to be made.
This document specifies requirements for surface preparation prior to application of a protective
treatment, and gives guidelines for application for such treatment in an informative annex.
This document gives options for specifying requirements to match project specific requirements.
This document is also applicable to temporary aluminium structures.
