European Union
steel standards

In the European Union structural steelwork is designed to the Eurocodes and executed to EN 1090-2, with CE marking under the harmonised standard and a declaration of performance from the fabricator. Material grades come from the EN 10025 and EN 10210/10219 families and welding quality is demonstrated through EN ISO 3834.
