EN 1090 – Structural Steel & Aluminum defines the requirements for execution of steel and aluminum structures, ensuring safety, quality, and regulatory compliance across EU and global markets.
What Is EN 1090?
EN 1090 is the European harmonized standard regulating the manufacturing, assembly and conformity of structural steel and aluminium components and constructions. It ensures that structural elements meet strict safety, performance and CE-marking criteria.
- Standardized structural performance and safety
- CE-marking compliance for steel and aluminum structures
- Harmonized harmonics across EU markets
- Improved reliability, traceability, and market acceptance
When and Why EN 1090 Matters
For any company involved in fabricating or supplying structural steel or aluminum parts – beams, columns, frames, façade elements, load-bearing structures – EN 1090 ensures compliance with EU regulations and market requirements. Without EN 1090 compliance and certification, structural components risk being rejected, legal penalties may apply, and liability increases.
Key Requirements of EN 1090
Complying with EN 1090 typically involves:
- Factory Production Control (FPC): documented production processes, quality control, traceability.
- Material traceability: monitoring steel/aluminum origins, certificates, quality records.
- Welding and assembly standards: certified welders, defined welding procedures, non-destructive testing when required.
- Quality documentation & CE marking: issuing Declarations of Performance (DoP), CE certificates, conformity records.
- Ongoing audits and re-certification: to ensure continuous compliance over time.
Who Needs EN 1090?
EN 1090 is mandatory for businesses in sectors such as:
- Structural steel fabrication & construction
- Metal frame construction (residential, commercial, industrial)
- Steel/aluminum façade and curtain wall manufacturing
- Bridge and infrastructure steel works
- Metal components suppliers and subcontractors
How to Comply with EN 1090
- Acquire the official EN 1090 standard documentation
- Set up a Factory Production Control (FPC) system
- Ensure materials traceability and certified welding procedures
- Document processes, inspections and quality checks
- Issue Declarations of Performance (DoP) and CE marking where required
- Pass external audits and maintain ongoing quality control

FAQ: EN 1090 – Structural Steel & Aluminum
Is EN 1090 mandatory?
Yes — for structural steel and aluminium components marketed under CE-marking in the EU, compliance with EN 1090 (or equivalent harmonized standard) is mandatory.
What happens if I don’t comply with EN 1090?
Products may be blocked from EU markets, CE marking is invalid, liability risks increase, and regulatory authorities may impose fines or sanctions.
Can small workshops follow EN 1090?
Yes, but they must implement proper Factory Production Control, maintain traceability, and ensure welding and material standards — even small producers can comply if procedures are followed.
Do I need official standard documents?
Yes. Only official EN 1090 documents guarantee compliance and are legally valid for audits or CE marking certification.
