SPCC Cold Rolled Carbon Steel Coil JIS G3141 0.3-3.0mm Precision Thickness Bright Finish Sheet

The SPCC cold rolled carbon steel coil is a general-purpose cold rolled grade produced in accordance with the JIS G3141 standard. Manufactured from hot rolled pickled substrate and cold reduced to precise gauge, the material offers a smooth, bright surface, tight thickness tolerances and consistent mechanical properties. It is widely used in precision manufacturing, automotive, appliance and general metalworking industries.

The coil is supplied in the cold rolled condition with bright or matte surface finish, available in thicknesses from 0.3mm to 3.0mm and widths from 600mm to 1500mm, with standard inner diameters of 508mm and 610mm. Each shipment is accompanied by a mill test certificate covering chemical composition and mechanical test results for complete quality assurance.

• Precision Thickness Control: tight gauge tolerances for demanding manufacturing applications.
• Bright Surface Finish: smooth, uniform surface suitable for painting, coating and direct use.
• JIS G3141 Compliance: full conformity with the Japanese cold rolled steel standard.
• Good Formability: suitable for bending, stamping and moderate drawing operations.
• Consistent Hardness: stable mechanical properties for high-speed processing lines.
• Flexible Edge Options: mill edge and slit edge supplied to suit specific requirements.

The SPCC cold rolled coil is used for automotive body panels, household appliance shells, office furniture, metal stampings, electrical enclosures and general precision components. Its smooth surface and precise gauge make it the standard cold rolled grade for manufacturers requiring high surface quality and dimensional accuracy.

Coils are protected with anti-rust oil and waterproof paper, secured with steel strapping and packed in export-grade seaworthy bundles with edge protection. Pre-shipment inspection is standard, with SGS and BV third-party testing available on request. Production is controlled under an ISO 9001:2015 quality system.

Our monthly supply capacity of 30000 tons supports both trial and contract orders with stable mill allocation. Contact our team with your required thickness, width and tonnage for competitive pricing and current production schedules.
