DC01/DC03 Cold Rolled Carbon Steel Coil

Our factory strictly follows the JIS G3141 standard in production. The chemical composition and mechanical properties of SPCC and SPCD products meet the standards precisely. The tensile strength of SPCC is controlled at 270–410MPa and the elongation is ≥28%; the tensile strength of SPCD is controlled at 270–370MPa and the elongation is ≥34%. Impurities are strictly controlled to avoid problems such as stamping cracks and surface defects.

Main Applications

Both DC01 and DC03 cold-rolled steel sheets conform to the EN 10130 standard. Their superior performance makes them suitable for various cold-forming applications, and the delivered products boast excellent quality and outstanding cost-effectiveness. DC01, as a general-purpose cold-forming steel sheet, offers advantages in moderate plasticity and uniform strength, with a yield strength of 140-280MPa and a tensile strength of 270-410MPa. It is easy to process and weld, meeting basic forming requirements such as simple bending and shallow drawing. Its cost is controllable, making it suitable for the production of general structural parts and non-appearance parts, demonstrating exceptional versatility.

DC03, as a deep-drawing grade steel sheet, offers even more superior performance. It has a lower yield strength (120-240MPa) and an elongation at break ≥34%. Its formability far surpasses that of DC01, enabling it to handle moderately complex stamping processes. It is less prone to cracking and wrinkling, and has a higher surface finish, making it suitable for products such as appliance housings and automotive interior panels that require both aesthetics and formability.

Our factory delivers steel plates that meet high-quality standards. The surface is free of obvious defects, with high flatness and strict dimensional accuracy control. Thickness and length/width deviations meet standard requirements. The plates are delivered in a standard annealed and flattened state, resulting in regular shape, no deformation, and no burrs.

Packaging Standards

Inner Packaging: Moisture-proof paper + plastic film

Outer Packaging: Galvanized iron corner protectors + steel strapping

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
