BS EN 1090-1 specifies 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.
BS EN 1090-1 covers also 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. BS 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/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, e.g. anodising of aluminium.
BS EN 1090-1 covers structural cold-formed members and sheeting as defined in EN 1993-1-3 and EN 1999-1-4. BS EN 1090-1 does not cover conformity assessment of components for suspended ceilings, rails or sleepers for use in railway systems.
NOTE: For certain steel and aluminium components, particular specifications for performance and other requirements have been developed. The particular specifications may be issued as an EN or as Clauses within an EN. An example is given in EN 13084-7 for single-wall steel chimneys and steel liners. Such particular specifications will take precedence in case of non-compliance with the requirements of BS EN 1090-1.
BS EN 1090-1 on steel structures and aluminium structures is relevant to:
A steel structure is a metal structure that is made of structural steel. Structural steel is very stiff in respect to its cross-sectional area and thus can support a high load without excessive sagging. Ease of extrusion makes aluminium a versatile structural material allowing the production of complex cross-sectional shapes, suitable for structures that cannot be developed from more conventional structural materials.
BS EN 1090-1 provides you with the best guidance on requirements that should be taken into account for the execution of structural steelwork and aluminium work. BS EN 1090-1 provide guidance on tolerances on dimensions and shape, structural characteristics, structural design, manufacturing characteristics, component specification. As a user of BS EN 1090-1, you can be ensured of performance characteristics for structural steel and aluminium components. With obedience and compliance to BS EN 1090-1, you can efficiently manufacture high-quality structural components. With BS EN 1090-1 you can be ensured that the products consistently meet and exceed quality assurance targets. BS EN 1090-1 provides you with comprehensive information useful throughout the process of production.
