DREAMS
Introduction of TATA STEELIUM 
In 2018, Tata Steelium completed a successful 15 years in its ongoing journey of excellence.
The brand was launched in 2003 at a time when the market for cold rolled steel was extremely 
fragmented and served by a host of undifferentiated products. This marked a milestone in the 
steel industry as Tata Steelium was the first branded Cold Rolled Steel in India, and perhaps in 
the world, offering a range of superior and consistent product benefits, authenticity and backed 
by unmatched service standards.
Tata Steelium serves a wide spectrum of customers which includes the auto ancillaries sector, 
the panel industry for electrical and telecom applications, the furniture industry and the 
packaging industry.
