EN 10080

EN 10080


The European standard EN 10080, established by the European Union (EU), delineates general requisites for ribbed weldable reinforcing steel utilized in reinforcing concrete structures. This standard encompasses steel supplied in the configurations of bars, coils (rods, wires), and decoiled products. It provides extensive information encompassing definitions, methodologies for testing, conformity assessment, as well as the identification of the manufacturer and the technical class. Furthermore, the standard incorporates specifications for three distinct steel grades, all possessing a characteristic yield strength of 500 MPa but exhibiting varying ductility characteristics. The three grades of reinforcing steel are denoted as B500A, B500B, and B500C, with the letter “B” signifying reinforcing steel. The letters A, B, or C elucidate the ductility levels of the steel, with class A indicating the lowest ductility and class C representing the highest

As per the provisions of EN 10080, steel products covered by this standard may exhibit a ribbed, indented or smooth surface. It is essential to note that this standard exclusively pertains to weldable reinforcing steel and does not extend its applicability to:

1.Non-weldable reinforcing steel,

2.Galvanized reinforcing steel,

3.Epoxy-coated reinforcing steel,

4.Corrosion-resistant reinforcing steel,

5.Prestressing steels, indented strip,

6.Further processing, such as cutting or cutting and bending.

It is noteworthy that the standard’s applicability extends to all European Union (EU) countries. For specific details and specifications regarding steel production in adherence to EN 10080, interested parties can refer to the relevant documentation outlining the specifications and guidelines provided by the standard.

The British Standard BS 4449, titled “Steel for the reinforcement of concrete. Weldable reinforcing steel; bar, coil and decoiled product.

This standard delineates the requirements for ribbed weldable reinforcing steel deployed in the reinforcement of concrete structures. Encompassing steel delivered in the form of bars, coils, and decoiled products, BS 4449 outlines specifications for three distinct steel grades, each characterized by 500 MPa yield strength but differing in ductility characteristics—designated as B500A, B500B, and B500C.

Weldability requirements for all steel grades are explicitly defined in terms of chemical composition, with a particular emphasis on the carbon equivalent value. It’s important to note that this standard does not cover steel bars produced by re-rolling finished products or rolling material with an incomplete or unknown metallurgical history.

BS 4449 primarily targets manufacturers, fabricators, and purchasers involved in ribbed reinforcing steel (bars, coils, and decoiled products) for concrete structure reinforcement. It offers designations based on steel grade, product form, and dimensions, serving as a comprehensive guide for specifying the technical requirements for reinforcing steels. This includes aspects such as chemical analysis, mechanical properties, rib geometry, and tolerances on dimensions
