EN 1090-1 sets out requirements for conformity assessment of performance characteristics for structural steel and aluminium components as well as for kits placed on the market as construction products. The conformity assessment covers the manufacturing characteristics, and where appropriate the structural design characteristics. EN 1090-1 also covers the conformity assessment of steel components used in composite steel and concrete structures. The components can be used directly or in construction works or as structural components in the form of kits.
EN 1090-1 applies to series and non-series structural components including kits. The components can be made of hot-rolled or cold-formed constituent products or constituent products produced with other technologies. They may be produced of sections or profiles with various shapes, flat products (plates, sheet, strip), bars, castings, forgings made of steel and aluminium materials, unprotected or protected against corrosion by coating or other surface treatment (anodising of aluminium).
EN 1090-1 covers structural cold-formed members and sheeting. The standard does not cover conformity assessment of components for suspended ceilings, rails or sleepers for use in railway systems. This standard is part of the EN 1090 series and it supersedes EN 1090-1:2009.
