Cold rolled steel coils in grades DC01 and SPCC-SD (or customized) engineered for precision stamping, structural forming, and high-end fabrication. Available in Full Hard for high yield strength or Black Annealed for superior ductility and formability with a clean dark matte finish. Supplied with full batch traceability and MTC (EN 10204 3.1).
Cold Rolled Steel Coil (CRC / SPCC-SD / DC01)
Authentic Steel supplies high-precision Cold Rolled Steel Coils (CRC) engineered through advanced cold-reduction processing, delivering superior surface smoothness, exceptionally tight dimensional tolerances, and consistent mechanical properties. Produced from pickled hot-rolled coils passed through modern cold-tandem rolling mills and precision tension levelers, our cold rolled steel coils serve as an essential raw material for demanding high-precision stamping, deep drawing, roll forming, and decorative surface-finishing applications.
Available in primary international commercial and deep-drawing grades—including SPCC-SD, DC01, ST12, and ASTM A1008—our CRC materials feature low surface roughness variation, excellent flatness, and uncompromised formability. Whether supplied in Full Hard (CRFH) condition for structural rigidity or fully annealed and skin-passed condition for complex deep-drawing parts, our coils guarantee reliable processing performance across automated high-speed production lines.
Exceptional Dimensional Accuracy & Tight Gauge Control: Advanced digital automatic gauge control (AGC) systems ensure ultra-tight thickness tolerances across the entire length and width of the coil.
Flawless Surface Finish & Superior Paintability: Clean, uniform surface texture (dull/matte finish or bright finish) provides an ideal substrate for electroplating, powder coating, zinc galvanizing, and painting.
Controlled Tempers & Mechanical Ductility: Customized annealing and skin-passing processes allow precise control over yield strength, tensile strength, and elongation to prevent stretcher strain marks during stamping.
Versatile Value-Added Processing: In-house coil processing capabilities include high-precision longitudinal slitting into narrow strips, tension-leveled flat sheet cutting, and customized edge trimming.
Full International Compliance: Manufactured in full accordance with ASTM, EN, JIS, and DIN standards, accompanied by official EN 10204 3.1 Mill Test Certificates (MTC) for total batch traceability.
Annealed & Skin-Passed (SPCC-SD / DC01): Re-crystallization annealed and lightly skin-passed to eliminate yield point elongation. Offers optimal ductility, flat surface contour, and excellent workability for deep drawing, bending, and precision forming.
Full Hard (CRFH): Direct cold-rolled material supplied without box annealing. Exhibits high tensile strength and hardness (HRB ≥ 85), making it ideal for flat uncoiling, light roll forming, direct galvanizing feedstock, or structural applications where stiffness is required.
Black Annealed: Controlled protective-atmosphere annealing creates a uniform dark, matte oxide film. Provides enhanced flexibility and ductility specifically suited for wire drawing, light section bending, hardware fittings, and furniture tubing.
Thanks to superior surface aesthetics, consistent temper properties, and tight gauge tolerances, our cold rolled steel coils serve critical manufacturing sectors worldwide:
Automotive Industry & Hardware Components: Precision auto body panel reinforcements, internal structural brackets, door hinges, seat slides, oil pans, and heavy-duty hardware fittings.
Home Appliances & Electrical Enclosures: Exterior cabinet panels for refrigerators and washing machines, computer server chassis, electrical junction boxes, cable trays, and steel office furniture.
Precision Tubing & Cold Roll Forming: Feedstock for high-frequency ERW welded mechanical tubes, light-gauge section steel, door frame profiles, and custom cold-formed structural channels.
Substrate Material for Metallic Coating: Serving as the premium base stock for electro-galvanizing (EG), continuous hot-dip galvanizing (GI), and tinplate (ETP) manufacturing lines.
To ensure uncompromised quality in every shipment, every production heat undergoes rigorous quality inspection protocols:
Digital Continuous Thickness Monitoring: Real-time laser gauge tracking ensures zero out-of-tolerance variation throughout the coil roll.
Mechanical & Chemical Property Testing: Destructive tensile, yield, elongation, and Rockwell hardness (HRB/HV) evaluations conducted per heat number.
Surface Roughness & Metallographic Analysis: Microstructure and surface Ra roughness verification to match customer painting or stamping specs.
Full Traceability & Certification: Issued with official EN 10204 3.1 Mill Test Certificates (MTC), certifying complete chemical composition and mechanical compliance.
To prevent corrosion, moisture ingress, or handling damage during ocean transit, Authentic Steel enforces multi-layer export packaging standards:
Anti-Rust Protection: Lightly oiled coating combined with volatile corrosion inhibitor (VCI) anti-rust paper and high-density waterproof PE film.
Reinforced Steel Armor: Heavy-duty inner/outer steel corner protectors, metal side cover discs, and radial/circumferential high-tensile steel straps on wooden pallets.
Tianjin Port Logistics Synergy: Located adjacent to Tianjin Port, China, we offer expedited vessel berth loading, container stuffing with anti-moisture desiccant bags, and competitive direct factory pricing for global buyers.
