At Shreeyam Power and Steel Industries Limited (SPSIL), we don’t just manufacture steel-we build the foundation for dreams. As a leading primary steel manufacturer and exporter, we are driven by the vision of shaping a stronger, more resilient future. Every beam of Sponge Iron, every Steel Billet, and every TMT Reinforcement Bar we produce is crafted with precision and care, designed to transform aspirations into reality. Our signature TMT bars, marketed under the trusted “National" brand, stand tall in projects that dream big—projects that push the boundaries of engineering and infrastructure.
For us, quality is a journey not a destination.
Our integrated steel plant, covering over 200 acres, features world-class production facilities and a 60 MW captive power plant. This infrastructure ensures we uphold strict quality and sustainability standards throughout manufacturing. With an annual production capacity of over 500,000 MT of long steel products, we proudly serve clients across India.
The process begins with iron ore, which is the primary raw material used in the production of TMT bars.
In the Direct Reduced Iron (D.R.I.) plant, iron ore is converted into sponge iron through a reduction process. This sponge iron is a precursor to steel.
The sponge iron produced in the D.R.I. plant is used as a feedstock for the steel melting process. It is highly porous and contains iron in a reduced state.
Sponge iron is melted in a steel melting shop (SMS), typically using Electric Induction Furnaces (EIF), to produce molten steel.
The molten steel from the steel melting process is then transferred to the Ladle Refining Furnace (L.R.F). In this stage, the steel is refined to achieve the desired chemical composition and temperature.
The refined molten steel is cast into billets using a Concasting Machine. This machine continues casting (Concast) the steel into solid shapes, which are then cut into billets.
The produced billet/bloom is an intermediate product. It is square in cross-section.
The billets are reheated in a Reheating Furnace to make them malleable for further processing. The heating process ensures that the billets reach the required temperature for rolling.
Finally, direct hot-cast or reheated billets are rolled into TMT bars using a series of vertical and horizontal continuous rolling mills. The bars are then subjected to a thermo-mechanical treatment (TMT) process, which involves rapid cooling to enhance their strength, flexibility, and durability.
Our Block Mill Technology shapes heated billets with exceptional precision, ensuring TMT bars have consistent strength, precise profiles, and minimal dimensional variations. Key features like automated sizing, efficient cooling, and reduced wear boost production speed, surface quality, and energy efficiency, making it ideal for high-load construction.
