Engineered to meet the exact mechanical and structural needs of metropolitan construction and manufacturing pipelines.
Mumbai, as the financial heart of India, has evolved into a massive epicentre for mega-infrastructure schemes, advanced automotive manufacturing corridors, and complex engineering works. The ongoing scale-up of projects such as the Navi Mumbai International Airport, the Mumbai Trans Harbour Link (MTHL), and the massive network expansions of the Mumbai Metro have created a highly specific and critical demand for high-strength Cold Rolled (CR) steel coils, sheets, and plates.
Unlike standard hot rolled metals, Cold Rolled steel undergo processing below its recrystallization temperature. This precision manufacturing yields superior dimensional accuracy, clean surface profiles, and refined structural grain structures. Consequently, for industries positioned throughout Maharashtra's automotive hubs (Pune-Chakan corridor) and structural metal fabrication units in Kalamboli, importing high-performance CR steel from advanced factories in China is essential to sustaining competitive quality and pricing benchmarks.
Strategically positioned to deliver high-capacity industrial metals under strict global quality frameworks.
Hansheng Technology (Hebei) Co., Ltd. is strategically situated in Tangshan City, Hebei Province—the heart of China’s steel industry. With a prime location just 150 kilometers from the Tianjin seaport and 150 kilometers from the capital, Beijing, we benefit from an exceptional logistics network that ensures efficient global shipping to Mumbai and major international ports. Since our inception in 2006, we have evolved into a comprehensive, export-oriented enterprise specializing in the manufacturing of premium-quality steel products.
We operate 8 high-efficiency production lines with a total annual production capacity reaching up to 650,000 metric tons. Our extensive product portfolio includes Galvanized Steel Wire, Hot/Cold Rolled Steel Coils and Sheets, GI/PPGI, GL/PPGL, and various Section Steels, all meticulously manufactured to adhere to rigorous international standards such as GB, JIS, ASTM, DIN, EN, and AS/NZS.
Utilizing high-end cold rolling mills and heat treatment processing to guarantee precise thickness control, high surface uniformity, and optimal mechanical ductility across all sheets and coils.
Every single batch is subjected to strict pre-shipment inspection processes in our ISO9001:2000 and ISO14001 certified mills, verifying compliance with ASTM, JIS, DIN, and GB specifications.
Our proximity to Tianjin Port ensures that custom CR steel shipments are processed and shipped rapidly, minimizing transit timelines to Mumbai’s Nhava Sheva (JNPT) port terminal.
A comparative analytical guide for procurement departments evaluating cold-rolled properties for heavy-duty systems.
In structural and manufacturing environments, selecting the appropriate cold-rolled grade directly determines the load-bearing integrity and operational longevity of final assemblies. Cold rolled steel exhibits yield strengths and tensile properties up to 20% higher than equivalent hot rolled steel. Additionally, its tight dimensional tolerance (typically +/- 0.05mm or less) ensures seamless processing in automated punching, laser cutting, and bending machinery.
| Steel Grade Category | JIS Standard | ASTM Standard | EN Standard | Key Applications in Mumbai Industry |
|---|---|---|---|---|
| Commercial Quality (CQ) | SPCC | ASTM A1008 CS | DC01 (EN 10130) | Electrical enclosures, steel furniture, ductwork & structural panels. |
| Drawing Quality (DQ) | SPCD | ASTM A1008 DS | DC03 (EN 10130) | Automotive press parts, machinery casings, complex bracket pressings. |
| Deep Drawing Quality (DDQ) | SPCE | ASTM A1008 DDS | DC04 (EN 10130) | Deep-drawn automotive components, filters, lighting reflectors. |
| Structural High-Strength | SPFC 340-590 | ASTM A1008 SS | HC260-HC420 | Elevated load brackets, chassis components, custom scaffolding joints. |
Due to the aggressive coastal climate of Mumbai, raw CR steel is frequently coated or treated to resist high-salinity corrosion. Our factories specialize in supplying high-ductility CR coils that undergo rapid zinc-coating (galvanizing) or conversion into Zinc-Aluminum-Magnesium (ZAM) structural systems, which deliver up to 5 times the corrosion resistance of standard galvanized steel in maritime climates.

Hot Rolled (HR) steel typically has larger dimensional tolerances (ranging from +/-0.15mm to +/-0.25mm) and a rougher surface finish due to the scaling that occurs during cooling. Cold Rolled (CR) steel is processed through additional finishing mills where tolerances are kept tight—often within +/-0.03mm to +/-0.05mm. This high accuracy is critical for high-end stamping, deep-drawing, and automated tooling used in Mumbai automotive and enclosure plants.
Cold rolled steel is highly sensitive to moisture and rust during sea shipping. To prevent corrosion, Hansheng Technology implements comprehensive protective packaging: applying anti-rust oil, wrapping the coils in VCI (Volatile Corrosion Inhibitor) paper, surrounding the batch with a high-strength steel outer shell, and adding heavy-duty structural steel bands. We also place silica desiccant bags within the core to absorb ambient moisture throughout the ocean voyage to Jawaharlal Nehru Port Trust (JNPT) in Mumbai.
Indian engineering groups commonly specify BIS standards (like IS 513 for cold-reduced carbon steel sheets). In global projects, standard equivalents such as ASTM A1008 (US), JIS G3141 (Japan), and EN 10130 (Europe) are widely used. Hansheng Technology fully complies with all these classifications, and we supply comprehensive Mill Test Certificates (MTC) indicating chemical analysis (C, Mn, P, S) and mechanical performance parameters.
Transit times from Tianjin Port (nearest to our Tangshan mill) to JNPT (Mumbai) vary depending on shipping line selections. On average, direct routes take 18 to 22 days. Transshipment routing through intermediate hubs can take between 25 and 30 days. We arrange direct sailings where possible to keep inventory pipelines tight and projects running on time.
Yes, our processing lines feature advanced slitting and shearing machinery. We supply CR coils in standard widths (such as 1000mm, 1219mm, and 1250mm) or slit them down to precise custom strip widths based on client specifications. We also offer both mill-edge and slit-edge options depending on the final stamping and roll-forming processes planned for the material.
