Steel - hot-dip galvanized steel

Emission intensity of steel - hot-dip galvanized steel. worldsteel 2023 study. Obtained by passing cold rolled coil through a molten zinc bath in order to coat the steel with a thin layer of zinc to provide corrosion resistance. It can be found on the market in coil or in sheets and is further processed into finished products by the manufacturers. Hot Dip Galvanized Steel features excellent forming properties paintability weldability and is suitable for fabrication by forming pressing and bending. Applications include domestic applications building applications (e.g. wall elements roofing applications) automotive applications (e.g. body in white for vehicles underbody auto parts) lighting fixtures drums and various kinds of sections applications profiled sheets etc. Typical thickness between 0.3 - 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. Contact Worldsteel for more information. At an EOL recovery rate of 85%. Module D impact of -1.21 kg CO2e per kg ('-' magnitude is a benefit '+' magnitude a burden). This gives a net life cycle inc Mod D of 1.41 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.
