Key Data Set Information
Location CN
Reference year 2006
Name
Hot rolled coil ; steel ; steel production
Use advice for data set When using this data set for Life Cycle Assessment, ensure to include the hot rolling phase as part of the gate-to-gate assessment. Consider the energy consumption and emissions during the heating and deformation process. If your assessment includes end-of-life modeling, account for the potential recyclability of the steel. Data users should also consider the regional differences in energy sources and technology levels which can affect the environmental impact of steel production.
Technical purpose of product or process The hot rolled coil is commonly used in the manufacturing of construction elements such as I-beams and rails, in automotive frames, and for producing pipes and tubing. It serves as a foundational material in heavy industry, specifically for large scale structural projects and manufacturing processes that require robust steel components.
