The structure underneath does not have to be aluminium. A concrete road bridge, an ageing steel footbridge, a quay wall or an external stair — the existing deck stays, the railing is replaced.
Galvanised and painted systems fail first at the fixings, where de-icing salt collects and the coating is thinnest. Aluminium removes that failure path entirely: the system is anchored to the structure in place, with no welding on site, and the anodised or powder-coated finish is not renewed across the service life. For a maintenance authority that converts a recurring annual line into a single capital item.
Standards
Every market names the same product differently and tests it against a different document. This is the first thing a tender committee checks.
Pedestrian parapets to BS 7818 classes P1–P6; pedestrian guardrail to highway authority specification.
Terms used: bridge parapet · pedestrian guardrailGeländer to the RiZ-ING standard drawings and ZTV-ING practice, in the type required by the owner.
Terms used: Brückengeländer · GeländerGC-räcke (SE) and GS-rekkverk (NO) for pedestrian and cycle routes; sillankaide (FI).
Terms used: bröracke · brurekkverk · sillankaideA vehicle parapet is a different product: it is crash-tested and classified by containment level and working width under EN 1317, not by horizontal load alone. If your scheme requires an N or H class, state it in the enquiry — we confirm in writing what we can supply before you build us into the specification.
Justification des matériaux
For a railing on an existing structure the comparison is not strength — both carry the load. It is what each one costs the owner after handover.
Less dead load added to a deck that was designed decades ago for something else.
Galvanising and paint systems have a finite life and must be renewed. Anodised aluminium does not.
Bolted installation: no welding permit, no fire watch, shorter closures over live traffic or track.
Over 95% of aluminium used in construction is recycled at end of life.
Pour les traversées financées par les municipalités, les gouvernements fédéraux et l'UE, la certification fait partie de la décision d'achat. Chaque devis est accompagné du dossier de conformité complet : calculs, déclarations de performance, modèles BIM et certificats de conformité.
