DC03 Cold Rolled Steel Coils and Sheets

DC03 steel is a commercial-grade low-carbon steel defined in the European standard EN 10130. The “DC” in its designation stands for “deep drawing,” explicitly indicating its core characteristic of being primarily used for deep drawing applications.

DC03 Cold-Rolled Steel Coil Advantages

Superior Deep-Drawing Performance: Low carbon content + uniform grain structure enables withstanding severe tensile and deep-drawing deformation without cracking or distortion.
High Surface Quality: Cold-rolling process yields a smooth, scale-free surface, facilitating subsequent operations like electrogalvanizing, hot-dip galvanizing, and pre-painting.
Good ductility and toughness: High elongation allows significant plastic deformation before fracture, enabling complex bending, flanging, and forming operations.

Applications of DC03 Cold-Rolled Steel

Automotive Industry: Body panels (doors, hoods), fuel tanks, mufflers, clutch plates, seat frames, and other internal structural components.
Home Appliances: Outer casings and internal components for refrigerators, washing machines, air conditioners; microwave oven panels; water heater liners.
Construction and Home Furnishings: Metal furniture, filing cabinets, lamp housings, decorative components, ceiling panels, etc.
General Hardware and Stamped Parts: Complex containers requiring deep drawing and stretching (e.g., filter housings, food containers, metal cans), server cabinets, computer cases, hardware stampings, bent parts.

What Products Can Be Processed from DC03 Cold Rolled Steel

1. HOT-DIP GALVANIZED STEEL COIL

Process: After cleaning and annealing DC03 cold-rolled steel coils, they are immersed in molten zinc for galvanization, followed by cooling and solidification.
Features: Exhibits various zinc flower structures on the surface, offering strong corrosion resistance and excellent workability.

2.ROGALVANIZED STEEL COILS

Process: Produced using DC03 cold-rolled steel coils as the substrate, applying pure zinc uniformly to the surface via electrolysis.
Features: Uniform, fine coating with a smooth surface and moderate corrosion resistance.

3. GALVALUME STEEL COIL

Process: The coating on DC03 cold-rolled steel coil contains 55% aluminum, 43.5% zinc, and 1.5% silicon.
Features: Superior corrosion resistance compared to hot-dip galvanized steel, excellent high-temperature performance, and outstanding heat reflectivity.

4. COLOR-COATED STEEL COIL

Process: Using DC03 cold-rolled coil, DC03 GI coil/GL coil as substrate, undergoes surface pretreatment followed by continuous application of multiple layers of organic coating on both sides, then baked for curing.
Features: Exceptional corrosion resistance combined with outstanding decorative properties.
