Sponge Iron
As one of the established sponge iron manufacturers in West Bengal, Adukia Industries operates a fully integrated sponge iron plant in West Bengal, producing sponge iron pellets and sponge iron fines that meet the raw material requirements of steel and TMT bar producers across the country. Every batch produced at our sponge iron factory undergoes strict quality checks before entering our integrated production chain. Along with our own pellets and in-house ferro alloys, sponge iron forms the raw material base for our billets, which are further rolled into TMT bars, wire rods, and HB wires, while the same backward-integrated process also supports our ERW pipes production.
Ferro Alloys
Ferro alloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese, aluminum, or silicon. They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production. Ferro alloys produced by us are used as raw materials for the manufacture of stainless steel products. We also sell specialised ferro alloys – low and medium carbon – for special steel applications. We sell ferroalloys of various grades, a finished product, to steel companies primarily in the states of Odisha, Jharkhand, Karnataka, Uttar Pradesh, Haryana and Rajasthan.
Pellets
Pellets are a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of sponge iron and in blast furnaces for the production of hot metal. The iron pellets are produced with cold crushing strength (CCS) of 210+ and porosity of 24+” which helps to maintain grade in DRI fem – 80+ and our product mean particle size (MPS) is ~9.5-10 which assists in reducing oxygen in kiln and maintain consistency in grade. Iron Pellets are used as raw material for sponge iron and blast furnaces.
AIC can produce various grades/quality of pellets because of having a rotary kiln where the pellets are heated and fired uniformly. The process can use multiple ores simultaneously by applying the art of raw material blending. Pellet process helps save energy i.e. power because of excellent heat recuperation and lower drop in pressure of gases.
Wire Rods
Adukia Industries is a leading wire rod manufacturer and a trusted name among advanced iron and steel producers, committed to providing innovative solutions for the wire drawing industry. We produce top-quality stainless wire rods for wire drawing mills across the globe. Our expertise in heat treatment and hot rolling billets on continuous rolling mills enables us to manufacture wire rods with the desired chemistry and mechanical properties. These semi-finished products feature a round cross-section and are wound up into wire rod coils for easy handling and transportation.
Why Adukia Industries Is Among the Top Wire Rod Manufacturers in India
As one of the established steel wire rod manufacturers in India, Adukia Industries operates a fully integrated production chain — from in-house sponge iron and billets to continuous rolling — giving us complete control over chemistry and consistency in every batch. This integration is what makes us one of the most reliable wire rod manufacturers in India for wire drawing units, fastener makers, and welding electrode producers. Every batch leaving our wire rod factory is tested against strict quality parameters, which is why dealers and industrial buyers continue to choose us as their preferred wire rod supplier for long-term requirements.

We offer customised billets for both domestic and international markets, catering to the demands of customers in Chhattisgarh, Uttar Pradesh, Punjab, Rajasthan, Maharashtra, Nepal, and Bangladesh, making us a reliable billet exporter to neighbouring countries as well.
Billets are sections of metal used for rolling into bars, rods, and sections. They are typically cast into rectangular or cross-sectional shapes, making them compatible with secondary processing. Billets are produced through continuous casting, extrusion, or indirect heat treatment, followed by hot rolling of an ingot or bloom. They serve as raw materials for manufacturing TMT bars and structural products used in construction. Given how much this stage shapes the strength and safety of every downstream product, you can read more about the importance of billet manufacturing in determining final steel quality.
Why Choose Adukia Industries for Billets
As one of the established steel billets manufacturers in India, Adukia Industries operates a fully backward-integrated production chain — from in-house sponge iron and pellets to ferro alloys — ensuring consistent chemistry and dimensional accuracy in every batch. This integrated control is what leading TMT and structural steel producers across the country rely on when choosing their preferred billet supplier. Backed by stringent testing and IS-compliant grades, we continue to be recognised among the leading billet manufacturers in India for both domestic and export requirements.
HR Coils
As one of the leading HR coils manufacturers in India, Adukia Industries produces high-tensile strength, high-carbon steel coils with a martensite grain structure. Our coils are created by passing them through a lengthy continuous heating furnace and then quenching them in oil, ensuring consistent strength and performance in every batch. Our hot rolled coils form the backbone of Adukia Industries' integrated production chain. The same HR coils are further processed into ERW pipes for plumbing, construction, and oil & gas applications, and re-rolled into TMT bars, wire rods, HB wires, and billets used across the construction and infrastructure sectors.
