EN 1090-3 : Execution of steel structures and aluminium structures - Part 3: Technical requirements for aluminium structures.

This document specifies the execution requirements for aluminium structures and structural components manufactured from rolled, extruded, cold-drawn, forged, or cast products. It applies to structures of any shape subjected primarily to static or fatigue loading, in accordance with execution classes linked to consequence classes. It covers components with a minimum thickness of 0.6 mm, or 1.5 mm when welded. For cold-formed ribbed sheets falling within the scope of FprEN 1090-5, the latter takes precedence. The document concerns structures designed in accordance with EN 1999 and provides for a reliability assessment when other rules or alloys are used. It also addresses surface preparation prior to protection, offers project-appropriate options, and applies to temporary aluminium structures.
