High-Quality DC01 Cold-Rolled Coils | GNEE Steel

As a leading steel supplier, GNEE Steel is committed to providing high-precision, reliable DC01 cold-rolled coils that adhere strictly to DIN EN 10130 standards (material number: 1.0330). Our DC01 cold-rolled coils are engineered for exceptional cold formability, superior surface quality, and consistent performance, making them the preferred choice for diverse industries worldwide. Whether for automotive manufacturing, home appliances, or metal fabrication, GNEE's DC01 coils deliver unmatched value and stability.

DC01 is a low-carbon cold-rolled steel grade designed for cold forming and light drawing applications.

Compared with hot-rolled steel, DC01 cold-rolled coils offer:

• Smoother and cleaner surface finish
• Higher dimensional accuracy
• Better bending and stamping performance
• Improved appearance after painting or coating

These advantages make DC01 an ideal choice for manufacturers who require precision and surface quality.

GNEE's DC01 cold-rolled coils stand out in the market due to our rigorous quality control and advanced production technology, with key advantages including:

Strictly Compliant Composition: Precisely controlled chemical components (C≤0.12%, Mn≤0.60%, P≤0.045%, S≤0.045%, Al≥0.020%) ensure excellent formability and weldability. Our internal tolerance is ±5% tighter than industry standards, guaranteeing consistent performance across every batch.

Superior Surface & Dimensional Accuracy: After professional pickling, cold rolling, and annealing, the coils feature a smooth, scale-free surface (Ra≤0.6μm) ideal for painting, plating, and other surface treatments. Thickness tolerance is controlled within ±0.02mm, exceeding EN 10130 requirements, to meet high-precision processing needs.

Stable Mechanical Properties: Yield strength ranges from 140-280 MPa, tensile strength from 270-410 MPa, and elongation (A80) ≥28%, enabling excellent bending, stamping, and shallow drawing without cracking. Each coil comes with a complete EN 10204 3.1/3.2 material test certificate for traceability.

Cost-Effective & Sustainable: As the basic grade in the DC steel family, DC01 balances performance and cost. GNEE's optimized production process reduces material waste, while the coils' lightweight properties help customers achieve energy-saving and emission-reduction goals.

GNEE's DC01 cold-rolled coils are versatile and widely applied in key sectors, leveraging their stable performance and adaptability:

Automotive Industry: Used for interior parts (door linings, dashboard brackets), non-load-bearing structural parts (trunk reinforcement, radiator supports), and stamping blanks. It meets the automotive industry's strict requirements for forming precision and reliability.

Home Appliances: Core material for refrigerator panels, washing machine shells, microwave oven interiors, and air conditioner casings. Its smooth surface ensures excellent paint adhesion, while its formability supports diverse appliance designs.

Metal Furniture & Office Equipment: Processed into table frames, file cabinet bodies, and storage shelves. It combines durability and aesthetic appeal, adapting to various bending and welding processes.

Electrical & General Fabrication: Ideal for electrical enclosures, distribution boxes, hardware accessories, and small mechanical stamping parts. Suitable for both small-batch customization and large-scale mass production.

With years of experience in global steel supply, GNEE Steel offers not only high-quality DC01 cold-rolled coils but also professional export services, competitive pricing, and reliable delivery schedules. Our strong supply chain and technical support help customers reduce procurement risk and improve production efficiency.

If you are looking for a trusted DC01 cold-rolled coil supplier, GNEE Steel is ready to support your project.

What is the difference between DC01 and DC04 steel?

DC04 and DC01 are both cold-rolled, unalloyed quality steels that are used for various industrial applications. While DC01 serves as the standard grade for general cold forming processes, DC04 is characterized by improved deep-drawing properties and higher ductility.

Is DC01 the same as CR4?

Cold Reduced steel

Here at GNEE Steel, we stock and process DC01 mild steel (often referred to as CR4), in varying thicknesses from 0.9mm up to 3mm. Each sheet is de-coiled and flattened to strict tolerances in our works, ensuring consistent quality and flatness, every time.

What does DC01 mean?

DC01 represents the basic grade of the DC steel family and is also known under the former designations St12 or FeP01. This grade can be used for simple forming operations such as bending, coining, beading and drawing.

What is the difference between DC01 and DC03?

DC01 – This grade can be used for simple forming work, e.g. bending, embossing, beading and drawing. DC03 – This grade is suitable for forming requirements such as deep drawing and difficult profiling.

What is DC01 steel equivalent to?

Material 1.0330, DC01 steel equivalent to ASTM, ISO, European (German DIN, British BSI, France NF), Japanese JIS and Chinese GB standard (for reference). Note: DIN 1623 has been replaced by DIN EN 10130, and the designation ST12 has been replaced by DC01.

What is the thickness of DC01 material?

Galvanized Steel Sheet - Grade Dc01, Thickness 0.2-3.50mm, Width 914-1250mm | Cold Rolled, Durable Zinc Coating, Long Lasting Toughness.

Is cold-rolled steel better than hot rolled steel?

Cold rolling produces steel with closer dimensional tolerances and a wider range of surface finishes than hot rolling. It is also up to 20% stronger than hot rolled through the use of strength hardening.
