Basic Grade Pig Iron (BG Grade) is produced by smelting selected iron ore with coke and fluxes such as limestone in high-efficiency blast furnaces. During this controlled process, the molten iron is refined to maintain low silicon content and a balanced chemical composition, making it ideal for steelmaking applications. The molten metal is cast into solid pig iron blocks, ensuring uniform quality, structural stability, and consistent performance.
BG Grade Pig Iron is primarily used in the manufacture of mild steel and various steel products through basic oxygen furnaces and electric arc furnaces. It serves as a reliable raw material for producing structural steel, construction materials, engineering components, and industrial equipment. Its controlled composition and metallurgical stability make it highly valued by steel plants and heavy industries worldwide.

Foundry Grade Pig Iron (FG Grade) is a high-purity iron produced through the smelting of carefully selected iron ore, coke, and limestone in modern blast furnaces. During this controlled metallurgical process, impurities are removed and the chemical composition is precisely maintained to achieve optimal carbon and silicon content required for casting applications. The molten iron is then cast into solid blocks, ensuring uniform structure, consistency, and dependable performance.
FG Grade Pig Iron is widely used in the manufacturing of grey iron castings, automotive components, engine blocks, pipes, machinery parts, and heavy engineering products. Its superior fluidity, strength, and casting properties make it an essential raw material for foundries and industrial manufacturers worldwide.

Steel Making Grade Pig Iron (SG Grade) is manufactured by smelting high-quality iron ore with coke and limestone in advanced blast furnaces under strictly controlled conditions. During this process, impurities are carefully reduced and the chemical composition is precisely regulated to achieve low phosphorus, controlled silicon, and optimal carbon levels required for efficient steel production. The refined molten iron is then cast into solid blocks, ensuring uniformity, purity, and consistent metallurgical performance.
SG Grade Pig Iron is primarily used as a key raw material in steel manufacturing through electric arc furnaces and induction furnaces. It enhances charge mix quality, improves melting efficiency, and contributes to the production of high-strength structural steel, engineering-grade steel, automotive components, construction materials, and industrial machinery.

High Silicon Grade Pig Iron is produced by smelting selected iron ore with coke and limestone in controlled blast furnace operations, where the silicon content is intentionally maintained at a higher level to meet specialized casting requirements. Through precise control of raw materials and furnace parameters, the molten iron achieves enhanced fluidity and improved metallurgical characteristics. The refined metal is then cast into solid pig iron blocks, ensuring uniform composition and consistent performance.
This grade is primarily used in foundries for the production of high-quality grey iron castings, automotive components, engine blocks, pipes, and intricate machinery parts. Its elevated silicon content improves castability, reduces shrinkage defects, enhances graphite formation, and ensures superior surface finish in finished castings.
