CEN/TC 135 Execution of steel structures and aluminium structures

European Norm

91.080.13   Steel structures | 91.080.17   Aluminium structures


This document specifies the product characteristics and performance criteria for steel components and aluminium components manufactured from steel or aluminium constituent products to be used for structural purposes in buildings and civil engineering works where their characteristic affects the mechanical resistance and stability of these construction works or parts thereof. This document only applies for components manufactured according to EN 1090-2:2018, FprEN 1090-3:2018, EN 1090-4:2018 and EN 1090-5:2017.
This document also gives methods for assessing the performance and specifies requirements for the assessment and verification of constancy of performance for these components.
This document covers series and non-series produced structural components including kits as well as steel parts of composite components.
This document does not cover (components for)
- Aluminium structural composite components,
- Amusement rides and devices which are machines or not permanently installed,
- Anchor channels for use in concrete,
- Balustrades unless fulfilling the function of a barrier,
- Blind rivets,
- Cabinets for cables and power supply installations,
- Cables, ropes and wires,
- Castings,
- Circulation fixtures except sign gantry and cantilevers,
- Components for suspended ceilings,
- Fasteners glued to timber structures,
- Fasteners for use in timber,
- Fasteners and anchors for use in concrete and masonry,
- Fastening plates and other cast into concrete fastenings,
- Flagpoles,
- Forgings,
- Foundation bolts, column shoes and pile joints cast into concrete,
- Joining devices for rail track isolation systems,
- Non-structural fences and railings,
- Ornamentations,
- Piles if non-fabricated,
- Pipelines and pipes,
- Playground equipment,
- Powder actuated fasteners,
- Prefabricated steel and stainless steel wire rope systems with end connectors,
- Prefabricated tension rod systems with end connectors,
- Racking and shelving systems, if not integral part of the load bearing structure of the construction works,
- Rails or sleepers for railway systems,
- Raised floors,
- Rebar connections,
- Reinforcing steel for concrete or masonry,
- Roof safety products incl. roof ladders and walkways,
- Scaffoldings,
- Sculptures (Metal Art),

- Steel and aluminium components and elements produced on site,
- Steel and aluminium stairs, walkways and fences forming integral part of a machine, silo, tank, etc.,
- Steel spring elements,
- Structural components for offshore structures,
- Structural double skin metal faced sandwich panels,
- Temporary structures (e.g. tents, fairground and amusement park machinery and structures)
- Traditional craft type and non-structural components (e.g. weather cocks, letter boxes, bicycle racks, fences),
- Tuned mass damper systems,
- Wind turbine towers.
