Introduction
In recent years, the Iranian steel market has witnessed significant fluctuations in price, supply, and logistics. The need for reliable suppliers of high-quality steel billets and sponge iron has therefore become essential for foundries, rolling mills, and steel manufacturing plants. With over two decades of experience, Sepahan Industrial Supplies Company has established itself as a trusted supplier, providing direct and certified access to the country’s leading steel producers. As an approved vendor for major oil, gas, and petrochemical projects, the company ensures the continuous, cost-effective, and high-quality supply of steel billets and sponge iron (DRI) for domestic and export markets.
🔹 Direct Supply of Steel Billets
What Is a Steel Billet?
A steel billet is a semi-finished product used to produce long steel sections such as rebar, angle bars, and structural beams. The billet’s composition and uniformity directly affect the mechanical and chemical properties of the final product.
Key Advantages of Buying Steel Billets from Sepahan Industrial Supplies
- Direct supply from top-tier Iranian producers — including Khouzestan Steel, Kaveh South Kish, Esfahan Steel, Arfa, and Jahan Foolad Sirjan.
- Factory test certificates and chemical analysis reports provided with each shipment.
- Flexible delivery options — ex-works, CIF, or delivered to customer’s site.
- Competitive pricing through direct sourcing — no intermediaries involved.
- Support for both domestic consumption and export orders.

| Grade | C (%) | Mn (%) | Si (%) | P (%) | S (%) | Typical Application |
|---|---|---|---|---|---|---|
| 3SP | 0.14–0.22 | 0.40–0.65 | 0.15–0.30 | ≤0.040 | ≤0.040 | General rebar & wire rod |
| 5SP | 0.28–0.37 | 0.50–0.80 | 0.17–0.37 | ≤0.035 | ≤0.035 | High-strength rebar |
| St37 | 0.17–0.20 | 0.35–0.65 | 0.15–0.30 | ≤0.045 | ≤0.045 | Structural steel |
| St52 | 0.20–0.22 | 1.50–1.60 | 0.55–0.60 | ≤0.040 | ≤0.040 | Heavy-duty and mechanical uses |
🔹 Direct Supply of Sponge Iron (DRI)
What Is Sponge Iron?
Sponge Iron (Direct Reduced Iron – DRI) is produced by reducing iron ore without melting it. It’s the key feed material for electric arc furnaces (EAFs) and induction furnaces, offering a clean, energy-efficient raw material for steelmaking.
Benefits of Purchasing DRI from Sepahan Industrial Supplies
- Guaranteed high metallic Fe content (≥ 90%)
- Low sulfur, phosphorus, and gangue content
- Sourced from leading Iranian DRI plants — such as Mobarakeh, Khorasan, and Chadormalu.
- Available in lumps, pellets, and fines.
- Fast and reliable logistics service to any destination in Iran or abroad.
📊 Table 2 – Typical Chemical Composition of Sponge Iron
| Parameter | Range | Unit |
|---|---|---|
| Total Fe | 88–93 | % |
| Metallization | 88–92 | % |
| FeO | 7–10 | % |
| SiO₂ | 3.0–4.5 | % |
| Al₂O₃ | 1.0–1.8 | % |
| P | ≤0.05 | % |
| S | ≤0.02 | % |
| Size | 3–18 mm | mm |
