Purpose and objectives

The standard EN 1090-2+A1:2024 outlines the technical requirements for the execution of steel structures across Europe. It aims to ensure that these structures are manufactured, assembled, and maintained to a consistent quality that meets safety regulations and performance criteria. By setting a clear framework for compliance, the standard helps organizations manage risks associated with structural integrity and longevity, thereby enhancing public safety and confidence in construction practices.

Scope: who must comply

EN 1090-2+A1:2024 is applicable to a wide range of industries involved in the construction and engineering of steel and aluminum structures, including:

• Manufacturers of structural steel components
• Construction companies that assemble or install these components
• Designers and engineers responsible for structural integrity

Typical company profiles include small to large-scale construction firms, metal fabricators, and engineering consultancies operating within the Construction Materials & Buildings context. Compliance is essential for companies seeking to operate within the European Union (EU) and the European Free Trade Association (EFTA).

How SN EN 1090-2+A1:2024 relates to other standards

EN 1090-2+A1:2024 is part of a broader suite of standards concerning construction and manufacturing, including:

• EN 1090-1: This standard addresses the assessment of conformity for structural components, serving as a foundational document for EN 1090-2+A1:2024.
• ISO 3834: Focuses on quality requirements for fusion welding of metallic materials, offering complementary guidelines that enhance welding practices within the scope of EN 1090-2+A1:2024.
• SIA 263.052+A1: A Swiss standard that provides additional regulations and guidelines for the execution of steel structures, aligning with the principles set forth in EN 1090-2+A1:2024.

Revision history and current status

The standard EN 1090-2+A1:2024 is published by CEN-CENELEC and is the most recent revision, incorporating essential updates to enhance compliance clarity and execution standards. Key changes in this revision include more detailed guidelines on corrosion protection measures, geometric tolerances, and the introduction of new execution classes that reflect the evolving industry practices. This ongoing revision process demonstrates the commitment to maintaining high safety and quality benchmarks in the construction sector.
