SPNG Group manufactures its own billets in-house through continuous casting — ensuring complete purity control from raw scrap to finished billet. This vertical integration is what gives Indostar TMT its superior quality.
"Purity That Shapes Strength" — our billets are produced using green steel manufacturing from ferrous scrap, reducing CO₂ emissions by 58% compared to virgin extraction.
The Indostar Lab is a NABL-accredited testing laboratory (ISO/IEC 17025:2017) — one of the most rigorous quality assurance facilities in the Indian steel industry. Every batch is tested before it leaves our facility.
From raw scrap to finished TMT bar — every step of the Indostar manufacturing process is automated and controlled in-house.
