Reach your sustainability targets
All SIJ Group steel is produced from recycled steel scrap in electric arc furnaces (EAF), without the use of iron ore. This results in a high recycled content and significantly lower CO₂ emissions compared to conventional blast furnace production routes.
By choosing SIJ steel, manufacturers can support their Scope 3 emissions reduction goals while maintaining the performance and quality.
Green² Steel
For customers with ambitious decarbonisation targets, Green² steel is produced using renewable electricity sources and delivers an additional 20–40% reduction in CO₂ emissions.
We are also developing an EPD library to provide verified sustainability data and support customer reporting requirements.
Supporting efficiency
As energy efficiency regulations become more demanding, material selection plays an increasingly important role in overall system performance.
SIWATT electrical steel helps manufacturers reduce energy losses and improve efficiency, contributing to lower operating costs and reduced environmental impact throughout the product lifecycle.
Technical expertise and application support
Selecting the right electrical steel impacts efficiency, performance and manufacturing success. Our specialists work closely with customers to support material selection, testing and application development.
