EN 10080

The European standard EN 10080 is a crucial guideline established by the European Union (EU) that outlines the general requirements for ribbed, weldable reinforcing steel used in concrete structures. This standard applies to steel provided in various forms, including bars, coils (rods, wires), and decoiled products. It offers comprehensive details on definitions, testing methods, conformity assessments, and the identification of both the manufacturer and the technical class. Key Points of EN 10080:

• Steel Grades: EN 10080 specifies three grades of reinforcing steel, all with a characteristic yield strength of 500 MPa but varying in ductility. These grades are labeled as B500A, B500B, and B500C, where the letter “B” indicates reinforcing steel, and the letters “A,” “B,” and “C” denote increasing levels of ductility, with “C” having the highest.
• Surface Characteristics: The standard covers steel products that may have ribbed, indented, or smooth surfaces, specifically focusing on weldable reinforcing steel.

Limitations of EN 10080: This standard does not apply to:

1. Non-weldable reinforcing steel.
2. Galvanized or epoxy-coated reinforcing steel.
3. Corrosion-resistant reinforcing steel.
4. Prestressing steels or indented strips.
5. Processes such as cutting or bending.

EN 10080 is applicable across all European Union (EU) member states, providing a unified framework for steel production. For detailed specifications, manufacturers and stakeholders can consult the relevant documentation.

British Standard BS 4449: Reinforcing Steel for Concrete

The British Standard BS 4449 complements EN 10080 by specifying the requirements for ribbed, weldable reinforcing steel used in concrete structures. Similar to EN 10080,BS 4449 applies to steel in bars, coils, and decoiled forms and categorizes steel into grades B500A, B500B, and B500C, each with 500 MPa yield strength but differing ductility levels. Weldability Requirements: BS 4449 emphasizes the importance of chemical composition, particularly the carbon equivalent value, to ensure weldability. However, this standard excludes steel bars produced by re-rolling finished products or material with an incomplete or unknown metallurgical history.

Certification Services by ATC INTL for EN 10080 and BS 4449

ATC INTL is a leading certification body offering comprehensive services for organizations seeking certification under EN 10080 and BS 4449. Our services include:

• Documentation Review: We begin by meticulously reviewing your organization’s documentation to ensure it meets the specifications of BS 4449 and EN 10080, including chemical compositions and mechanical properties.
• On-Site Assessment: Certified auditors from ATC INTL conduct on-site evaluations to verify the implementation of welding processes and compliance with the standards, specifically for ribbed reinforcing steel in bars, coils, and decoiled products.
• Weldability Compliance: We ensure that your steel products meet the weldability requirements for various grades, focusing on chemical composition and carbon equivalent value.
