JSW, AMNS, TATA CR Slit Coil Supplier
Leading CR Slit Coil Supplier & Manufacturer
Mechanical & Structural Uniformity
Our cold rolled strips feature micro-structural homogeneity that helps prevent unexpected yield-point elongation during continuous stamping processes.
Controlled grain configurations optimize plastic deformation parameters ($r\text{-value}$ and $n\text{-value}$ indices) to minimize structural fracturing during extreme metal forming operations.
Sterling Steels Co. is a premier processor, stockholder, and supplier of high-quality Cold Rolled (CR) Slit Coils, strategically headquartered in the industrial zone of Taloja MIDC, Navi Mumbai. Operating a state-of-the-art steel service center, the company specializes in processing and distributing prime-grade cold rolled steel strips that cater to the stringent demands of modern manufacturing. As a trusted B2B partner, Sterling Steels Co. bridges the gap between major steel producers and downstream industries, ensuring a steady supply of precision-processed raw materials.
The company maintains strategic sourcing partnerships with India’s leading steel manufacturers, including Tata Steel, JSW Steel, and ArcelorMittal Nippon Steel (AM/NS India) . By processing certified prime materials directly from these tier-1 mills, Sterling Steels Co. guarantees consistent mechanical properties, superior surface finishes, and precise thickness uniformity. Their extensive inventory supports a diverse product portfolio, ranging from standard commercial grades to specialized deep-drawing (DDQ) and high-tensile structural steel grades.
Advanced Slitting Technology & Tooling Physics
Equipped with high-rigidity slitting heads and automated loop tension adjustments, we process primary wide master coils into narrow precision strips. To achieve clean, square-cut profiles, our operators use a specific horizontal and vertical knife clearance configuration based on the target material's ultimate tensile strength (UTS) and thickness profile ($t$).
Proper tool centering helps eliminate edge camber deformation and limits burr height to less than 10% of the material thickness. Additionally, advanced multi-mandrel recoiling units apply uniform rewind pressure across all slit strands. This helps prevent telescoping issues and maintains flat, stable inner-wrap dimensions ($508\text{ mm} / 610\text{ mm}$ IDs) for smooth payoff performance on automated uncoilers.
Our close thickness monitoring keeps gauge variations well within the restrictive parameters specified by **IS 513 (Part 1)** and **DIN EN 10131** standards. This protects multi-stage progressive stamping dies from damage caused by unexpected material over-thickness.
