DIN EN 1090
Definition
DIN EN 1090 is a European standard that sets requirements for the manufacturing of load-bearing steel and aluminum structures. It governs conformity assessment, factory production control, manufacturer certification, and CE marking for load-bearing components made of steel and aluminum that are marketed as construction products.
Execution Classes
DIN EN 1090 defines four execution classes (EXC) for components:
- EXC1: Simple components such as stairs, railings, or conservatories on residential buildings
- EXC2: Components that do not fall into EXC1, EXC3, or EXC4
- EXC3: More complex structures such as bridges, towers, masts, crane tracks, and stadium roofs
- EXC4: Structures with high risk to people and the environment in case of failure
Materials
The standard mainly applies to:
- Steel
- Aluminum
- Alloyed and unalloyed steels
Applications
DIN EN 1090 is used in various sectors:
- Construction
- Bridge building
- Industrial facilities
- Stadium structures
- Towers and masts
- General steel and metal construction
Standards and Certifications
DIN EN 1090 consists of several parts:
- DIN EN 1090-1: Governs the conformity assessment procedure
- DIN EN 1090-2: Specifies technical requirements for steel structures
- DIN EN 1090-3: Defines requirements for aluminum structures
- CE Marking: Mandatory since July 1, 2014 for load-bearing steel and aluminum components in the EU
- Certification of factory production control (FPC) by an independent body
