EN 1090 Certification for Structural Steel and Aluminium | PRVÁ ZVÁRAČSKÁ, a. s.
Introduction
In modern construction, structural steel and aluminium components must meet strict safety, performance, and regulatory requirements. From buildings to bridges, the reliability of load-bearing elements depends on controlled fabrication and verified quality systems.
The EN 1090 standard establishes the requirements for manufacturing structural components and enables CE marking within the European Economic Area.
With the expertise of PRVÁ ZVÁRAČSKÁ, a. s., manufacturers can achieve certification and meet European construction compliance requirements.
What is EN 1090?
EN 1090 is a European standard that governs the fabrication and conformity of structural steel and aluminium components. It ensures that construction products meet essential safety and performance criteria before being placed on the market.
The standard applies to:
- Steel structures
- Aluminium structures
- Load-bearing components used in construction
It is mandatory for CE marking of structural components within the EU.
Structure of EN 1090
The EN 1090 series is divided into key parts:
- EN 1090-1 – Requirements for conformity assessment and CE marking
- EN 1090-2 – Technical requirements for steel structures
- EN 1090-3 – Technical requirements for aluminium structures
These parts define the framework for production, testing, and compliance.
Execution Classes (EXC)
EN 1090 defines execution classes based on risk, complexity, and consequences of failure:
- EXC1 – Low-risk structures
- EXC2 – Standard structures
- EXC3 – High-risk structures
- EXC4 – Critical structures
Higher execution classes require stricter control, inspection, and documentation.
Typical Applications
EN 1090 applies to:
- Commercial and industrial buildings
- Bridges and infrastructure projects
- Towers and masts
- Stadiums and complex architectural structures
- Offshore and energy-related structures
It is essential for manufacturers supplying structural components in Europe.
Core Technical Requirements
To comply with EN 1090, manufacturers must implement a robust quality system:
1. Factory Production Control (FPC)
- Documented production system
- Process control and monitoring
- Defined responsibilities and procedures
- Continuous internal audits
2. Welding Quality Requirements
- Compliance with EN ISO 3834
- Approved Welding Procedure Specifications (WPS)
- Qualified Welding Procedure Qualification Records (WPQR)
- Certified welders
3. Personnel Qualification
- Competent welding coordinators (IWE/IWT/IWS)
- Skilled operators and inspectors
- Defined roles and responsibilities
4. Inspection and Testing
- Visual inspection (VT)
- Non-destructive testing (UT, RT, MT, PT)
- Inspection plans and acceptance criteria
- Documentation of results
5. Material Traceability
- Identification of materials
- Certification in accordance with standards such as EN 10204
- Traceability throughout production
6. Documentation and Records
- Technical documentation
- Production records
- Inspection reports
- Declaration of Performance (DoP)
CE Marking under EN 1090
To place structural components on the European market, CE marking is required under EN 1090:
- Implementation of Factory Production Control
- Initial inspection by a Notified Body
- Certification of conformity
- Preparation of Declaration of Performance (DoP)
- Affixing the CE mark
Certification bodies such as PRVÁ ZVÁRAČSKÁ, a. s. conduct audits and issue certification.
