EN 1090 or BS EN 1090
What is the standard for structural steel and aluminium?
The EN 1090 or BS EN 1090 standard establishes the essential characteristics that structural steel and aluminum components must meet to ensure their structural integrity, durability, and safety. It also sets out the requirements for assessing and verifying these characteristics through a conformity assessment process, including factory production control, welding qualifications, and ongoing surveillance.
The BS EN 1090 standard consists of multiple parts that address different aspects of the execution of steel and aluminum structures. These include the following:
- BS EN 1090-1: Execution of steel structures - Part 1: Requirements for conformity assessment of structural components: This part specifies the requirements for assessing and verifying structural components used in steel structures. It covers the manufacturer's quality management system, welding processes, inspection, and certifying procedures.
- BS EN 1090-2: Execution of steel structures - Part 2: Technical requirements for the execution of steel structures: This part provides technical requirements for the execution of steel structures. It includes criteria and procedures for welding, fabrication, and assembly of steel components and structures.
- BS EN 1090-3: Execution of steel and aluminum structures - Part 3: Technical requirements for aluminum structures: This part focuses on the technical specifications for the execution of aluminum structures. It covers welding, fabrication, and assembly processes specific to aluminum components and structures.
