SPCC Cold Rolled Carbon Steel Coil 0.3-3.0mm JIS G3141 Bright Finish For Vietnam Manufacturing Industry

Our SPCC Cold Rolled Carbon Steel Coil manufactured to JIS G3141 specifications represents the premium choice for Vietnam's rapidly growing manufacturing sector. SPCC (Steel Plate Cold Commercial) grade delivers exceptional surface quality with bright annealed finish, tight thickness tolerances of ±0.03mm, and consistent flatness that meets the exacting requirements of automated stamping and press-forming operations. The cold rolling process imparts superior surface smoothness (Ra ≤0.8μm) and enhanced mechanical properties through work hardening, making it the material of choice for visible surface applications in consumer appliances and automotive body panels.

Manufactured using advanced production techniques and rigorous quality control processes, our carbon steel coils deliver exceptional performance across diverse industrial applications. With an annual production capacity exceeding 500,000 metric tons, we maintain a robust supply chain that guarantees consistent availability and competitive lead times for bulk procurement. Our mills utilize state-of-the-art continuous casting and controlled rolling technology to achieve precise dimensional tolerances and superior surface finishes. Each coil is subjected to comprehensive mechanical testing including tensile strength analysis, yield strength verification, elongation measurement, and dimensional inspection before shipment.

• JIS G3141 Precision Quality: Produced to exacting Japanese Industrial Standards with guaranteed chemical composition (C ≤0.15%, Mn ≤0.60%, P ≤0.100%, S ≤0.050%) and tightly controlled mechanical properties. Annealed condition offers tensile strength 270-410 MPa with elongation ≥28%.
• Bright Annealed Surface Excellence: Continuous bright annealing under protective atmosphere (HNX) produces a mirror-like surface finish free from oxidation and decarburization, eliminating the need for post-processing before painting, powder coating, or electroplating.
• Vietnam Manufacturing Ready: CO Form E preferential certificate of origin under ACFTA framework reduces import duties for Vietnamese buyers. Hai Phong and Ho Chi Minh City port delivery routes with 7-10 day transit time from major Chinese ports.
• Multiple Temper Options: Available in full hard, half hard, quarter hard, and fully annealed tempers to match specific forming requirements from simple blanking to complex deep drawing operations in progressive die setups.
• Consistent Dimensional Control: Advanced AGC (Automatic Gauge Control) and hydraulic AGC systems on 6-high reversing mills maintain thickness tolerance within ±0.03mm across the full coil length, ensuring consistent part quality in high-volume production.

SPCC cold rolled steel coils serve as the foundational material for Vietnam's manufacturing ecosystem spanning multiple high-growth sectors. In the home appliance industry, SPCC is used for washing machine cabinets, refrigerator outer panels, microwave oven cavities, water heater shells, and air conditioner chassis components requiring excellent surface appearance. The automotive sector utilizes SPCC for inner body panels, seat frame components, fuel tank brackets, and various stamped structural parts where deep drawability is critical. Electronics applications include computer chassis, server rack enclosures, electrical panel boxes, and LED lighting fixture housings. Additional markets encompass office furniture (filing cabinets, desk frames), metal door manufacturing, industrial shelving systems, and general sheet metal fabrication workshops throughout Vietnam's industrial zones in Bac Ninh, Binh Duong, and Dong Nai provinces.

These carbon steel coils are extensively utilized across heavy industry sectors where structural integrity and cost efficiency are paramount. The consistent mechanical properties across the entire coil length ensure reliable performance in automated stamping, roll forming, and CNC processing lines. End users benefit from reduced material waste and improved throughput compared to lower-grade alternatives. Our technical team provides complimentary application engineering support to help customers optimize material selection for their specific fabrication requirements, including formability analysis and welding procedure recommendations.

Every coil is professionally packed with waterproof kraft paper, anti-rust oil coating, and galvanized steel strapping. Inner diameter protection rings and edge guards prevent transit damage. Standard coil orientation is eye-to-sky on wooden pallets with full plastic wrapping for maritime container shipping. Each shipment includes a detailed mill test certificate (MTC) documenting chemical composition, mechanical properties, and dimensional measurements. We maintain ISO 9001:2015 certified quality management systems with third-party inspection available upon request from SGS, Bureau Veritas, or TÜV. Our after-sales guarantee covers manufacturing defects, and our logistics team handles customs documentation including Form E, CO, and fumigation certificates for smooth import clearance in Vietnam and beyond.
