Regulatory Compliance and Standards for Aluminium Extruded Sections

Aluminium extruded sections are widely used in construction, automotive, and other industries due to their strength, durability, and aesthetic appeal. To ensure the quality and safety of these products, comprehensive regulatory compliance and standards have been established.

International Standards

ISO 9001:2015 is the global standard for quality management systems. It provides a framework for organizations to establish and maintain a quality management system that meets customer and regulatory requirements. Aluminium extruded section manufacturers must adhere to ISO 9001 to demonstrate their commitment to quality and continuous improvement.

EN 12020-2 is a European standard that specifies the requirements for aluminium extruded sections used in curtain walling applications. It includes provisions for dimensional tolerances, material properties, and performance requirements. Compliance with EN 12020-2 ensures that extruded sections meet the safety and quality standards required for curtain walling systems.

Regional and National Regulations

In addition to international standards, there are also regional and national regulations that apply to aluminium extruded sections. For example:

ASTM B221 is an American standard that establishes the specifications for aluminium and aluminium-alloy extruded bars, rods, shapes, and tubes. It includes provisions for chemical composition, mechanical properties, and dimensional tolerances.

BS EN 12020-2:2008 is the British standard that corresponds to EN 12020-2. It provides the same requirements for aluminium extruded sections used in curtain walling applications in the United Kingdom.

JIS H 4040 is the Japanese standard that specifies the requirements for aluminium extruded sections used in construction. It includes provisions for material properties, dimensional tolerances, and performance requirements.

Material Properties

Regulatory compliance and standards also address the material properties of aluminium extruded sections. Common properties include:

Tensile strength: The ability of the material to resist being stretched or pulled.

Yield strength: The point at which the material begins to deform plastically.

Elongation: The percentage of stretch before the material breaks.

Corrosion resistance: The ability of the material to withstand chemical reactions that can cause degradation.

Performance Requirements

In addition to material properties, performance requirements also play a role in regulatory compliance. These requirements typically include:

Structural integrity: The ability of the extruded section to withstand applied loads and forces.

Fire resistance: The ability of the extruded section to resist fire and prevent the spread of flames.

Weather resistance: The ability of the extruded section to withstand exposure to environmental conditions such as rain, UV radiation, and extreme temperatures.


Regulatory compliance and standards for aluminium extruded sections provide a framework for ensuring the quality, safety, and performance of these products. By adhering to these standards, manufacturers can demonstrate their commitment to meeting industry requirements and delivering products that meet the needs of customers. Architects, engineers, and other users can rely on these standards to specify and use aluminium extruded sections with confidence in their reliability and durability.
