7 Steel Reinforcing Steel (Rebar)
Hot-rolled ribbed steel reinforcing bar (rebar) for reinforced concrete. Made in Cardiff from 100% recycled scrap in an electric-arc furnace. The EPD declares 330 kgCO2e/tonne at A1-A3, for a declared unit produced with a 100% renewable electricity mix with guarantee of origin. Reinforcement is a core structural material; the EPD covers A1–A3 + end-of-life + recycling benefit (module D).

Comparison Status
The record contains the basic metadata required for a controlled comparison. Products must still perform the same function and use compatible units, PCRs and lifecycle scope.
Design & Specification Notes
Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.
