Steel - Cold Rolled Coil

Emission intensity of steel - cold rolled coil. worldsteel 2023 study. Obtained by a further thickness reduction of a pickled hot rolled coil. This step is achieved at low temperature in a cold-reduction mill. It can be found on the market in coil but requires a further heating process before being manufactured into finished products. The various types of cold rolled steel are used as primary material for finished cold rolled coils & coated coils. Typical thickness between 0.15 - 3 mm. Typical width between 600 - 2100 mm. System expansion was used on the steel e.g. for blast furnace slag and other co-products. The influence of system expansion to the GWP for steel products is 3 to 7% lower GWP.

This gives a net life cycle inc Mod D of 1.27 kg CO2e per kg. The source does not clarify if the kgCO2e value is calculated using the IPCC Fourth Assessment Report (AR4) or IPCC Fifth Assessment Report (AR5) or IPCC Sixth Assessment Report (AR6) methodologies.
