All our steels for reinforced concrete are in Class C

C for Construction in safety

Class C is the name given by the design Eurocodes to so-called high-ductility steels for use in seismic areas.


High Ductility is expressed by defining two essential performance characteristics:

  • Rm/Re ratio (maximum tensile strength/yield stress) ≥1.15 as a guarantee of high plastic reserve;
  • Elongation at maximum load Agt≥7.5 as high capacity of deformation, and hence ductility.


Our production choice is characterized by ensuring the performance of the C-Class on all our products, even when this is not an express normative requirement.

For Alfa Acciai Class C means capability and continuous commitment to product and process innovation and optimisation, giving high-ductility steels with characteristics that remain constant through time. These characteristics are fundamental as they allow our customers, especially at the conversion stage to optimise their process parameters and achieve a high standard of production.
