EN 10080 specifies general requirements for ribbed weldable reinforcing steel used for the reinforcement of concrete structures.
The standard applies to steel delivered in bars, coils (bar, wire) and uncoiled products. The standard contains detailed definitions, test methods, evaluation and determination of manufacturer and technical grade compliance, provisions for three steel grades, all yield strength characteristics of 500 MPa, but different ductility properties.
Steel products according to this standard have ribbed, recessed or smooth surfaces.
The standard applies only to weldable reinforcing steel and cannot be applied to:
● Non-welded reinforcing steel;
● Zinc-plated reinforcing steel;
● Epoxy-coated reinforcing steel;
● Corrosion-resistant reinforcing steel;
● Prestressed mild steel; notched strip;
Further processing such as cutting or cutting and bending.
Ribbed and recessed steel products within the scope of this European standard are characterised by their surface geometry, which ensures adhesion to the concrete. The bonding requirements for ribbed and concave reinforcing steels will be based on the surface geometry.
Alternatively, the adhesion requirements for ribbed and recessed reinforcing steels can be determined by means of appropriate adhesion tests. The evaluation criteria for these tests must comply with the relevant product specifications or design standard. In this case provisions will also be made for the establishment of factory production control requirements for surface geometry based on the results of the adhesion tests.
