About EN1090
As well as offering certification to EN ISO 3834:2021 the international Standard defining Quality Requirements for Fusion Welding of Metallic Materials, OMNi audit and providing certification to EN 1090.
OMNi are a registered Notified Body (NB:2819) and are listed on the NANDO website as a provider of certification for EN1090 within the EU 27. OMNi is also accredited by INAB for ISO 17065:2012.
So, what is EN 1090
EN 1090 is a mandatory European Standard for the fabrication and assembly of steel and aluminium structures, requiring manufacturers to implement Factory Production Control (FPC) and affix a CE Mark (or UKCA mark in the UK) to prove their products meet strict quality, safety, and performance criteria for installation in the EU and UK.
It ensures structural integrity for components like building frames, bridges, and stadium roofs, categorizing them into Execution Classes (EXC1-EXC4) based on risk, from simple farm buildings to high-risk structures.
Under the amended Construction Product Regulations 305/2011 and now the revised CPR 2024/3110, it is a legal requirement for all construction products to be CE marked, hence this is a legal requirement for structural steel and aluminium.
Who Is This For?
Manufacturers, importers, and distributors of steel and aluminium components used in construction — including structural steel buildings, bridges, supports, roofing, gates, doors, windows, tanks, and reservoirs.
If your organisation fabricates or supplies structural steel or aluminium products for the EU or UK market, EN 1090 certification is a legal requirement under the Construction Product Regulations.

Key Aspects of EN 1090 - Structural Steel CE Marking
Legal Requirement
A legal necessity under the Construction Product Regulations (CPR) for selling structural steel and aluminium in Europe.
Parts of the Standard
EN 1090-1 covers conformity assessment (CE marking rules). EN 1090-2 covers technical requirements for steel. EN 1090-3 covers aluminium structures.
Execution Classes
Determines the level of control needed, from basic (EXC1 for farm buildings) to high-risk (EXC4 for stadiums, power stations).
Factory Production Control
A system to ensure consistent product quality, similar to ISO 9001, requiring regular surveillance.
CE Marking
Marks the product as compliant, allowing it onto the market, and requires a Declaration of Performance (DoP).
