TGC Iran – Premium Semi-Finished Steel Billets for Industrial & Construction Applications
Steel billet (or steel ingot / semi-finished billet) is a core intermediate product in the steelmaking and metal-working value chain. After raw materials such as iron ore, concentrate, sponge iron or scrap are melted in a furnace, the molten steel is cast or rolled into billets — solid bars with uniform cross-section (typically square or rectangular) and standardized dimensions — ready to be processed into finished steel products.

At TGC Iran, we supply high-quality steel billets with controlled chemical composition and physical properties, tailored to meet the demanding requirements of downstream steel mills, rolling mills and forging operations.
After mining and beneficiation of raw iron ore (or concentrate), the fine iron-bearing powder is mixed with binding agents such as bentonite, limestone or dolomite, moisture, and other additives. Through a sequence of agglomeration — in pelletizing drums or discs — the mixture forms spherical pellets. These “green pellets” are then dried, hardened (indurated) in kilns at high temperature (usually 1200–1300 °C), cooled down, and screened for uniform size. The result: dense, hard, spherical pellets with controlled porosity and excellent metallurgical properties.
Pellets are sized typically between about 6 and 16 mm in diameter. Their iron content typically ranges from around 63 % up to 70 % (often ≈ 65 %) after proper processing — depending on the raw material and beneficiation process.
Key Quality Parameters of Pellets
When evaluating the quality of iron ore pellets, the following parameters are critical:
Iron (Fe) content: High Fe grade reduces the amount of gangue and slag, improving furnace yield and efficiency.
Impurities (SiO₂, Al₂O₃, P, S, etc.): Lower impurity content leads to higher quality steel and reduces furnace issues.
Mechanical strength (compressive strength, abrasion resistance): Ensures pellets survive handling, transport, and loading without excessive breakdown.
Porosity and structure: Proper porosity allows efficient gas-solid interactions inside furnaces, which improves reduction reactions and energy efficiency. Wikipedia+1
Size uniformity: Uniform pellet size ensures even burden distribution in the furnace, stable airflow, predictable reduction behavior
Typical Sizes, Grades and Specifications
Depending on the producer and intended use, steel billets can vary in:
Cross-section: commonly square or rectangular (e.g. 100×100 mm, 125×125 mm, 130×130 mm, 150×150 mm)
Length: often 6 meters or 12 meters for standard billets Parsin Steel+1
Steel Grade / Chemical Composition: different grades (e.g. low-carbon mild steel, carbon steel) are produced depending on desired properties (flexibility, strength, machinability).
Physical & Mechanical Properties: uniform internal structure without defects (e.g. cracks, pores), consistent grain structure, good workability under hot/cold processing. SteelScope+2Green Gubre Group+2
TGC Iran ensures that each billet batch meets stringent quality control standards: chemical analysis, physical integrity, consistent dimensions, and suitability for further rolling or forging.
Why Steel Billets Are Essential in Steel Supply Chain
Using billets offers several advantages:
Versatility: Billets can be transformed into a wide variety of steel products — rebars, rods, wire, structural profiles, beams, and more. Green Gubre Group+1
Efficiency & Cost-Effectiveness: As a semi-finished standardized input, billets simplify production logistics, reduce waste, and enable streamlined rolling or forging operations. SteelScope+1
Quality & Consistency: Uniform composition and structure help ensure predictable mechanical properties and better control over final product quality. Wermac+2Montriam+2
Broad Industry Applications: From construction (rebars, structural steel) to manufacturing (machinery parts, wire, rods) and heavy industry — billets provide foundational feedstock for nearly all downstream steel products. Sree Metaliks+1
Steel billets supplied by TGC Iran are suitable for production of
Reinforcing bars (rebars) for concrete structures
Structural steel profiles, beams, angles, channels
Wire rods, round bars, rods for industrial use
Forged or drawn steel components — shafts, machine parts, fasteners
Pipes, tubes, hollow sections (after suitable processing)
Whether for construction, infrastructure, automotive, manufacturing or heavy machinery — billets act as the reliable base material to build almost any steel-based product.
