Spain’s Structural Code (Código Estructural), approved by Royal Decree 470/2021, replaced the earlier concrete and steel codes (EHE-08 and EAE). It allows only weldable reinforcing bars and coils that conform to UNE-EN 10080, in grades B 400 S, B 500 S, B 400 SD and B 500 SD.
Construction products covered by a harmonised European standard are CE marked once the manufacturer has drawn up a declaration of performance. The EU’s Construction Products Regulation (EU) 2024/3110 has applied since 8 January 2026, replacing Regulation (EU) No 305/2011.
