When sourcing SPCC vs DC01 cold rolled steel coil, buyers often face confusion over which grade meets their application requirements. Both materials are widely used in automotive, appliance, and construction industries, but their chemical composition, mechanical properties, and surface finish differ significantly. Understanding these differences is critical for optimizing production costs and ensuring product performance. At ChinaCNU Steel, we have exported over 500,000 tons of cold rolled steel from our factory in Boxing, Binzhou since 2006, helping clients in 80+ countries select the right grade for every project. This guide provides a direct comparison based on JIS G3141 and EN 10130 standards, with real pricing data and application insights.

Chemical Composition and Mechanical Properties
The core difference between SPCC and DC01 lies in their chemical limits. SPCC allows up to 0.15% carbon, while DC01 caps at 0.12%. This gives SPCC slightly higher hardness but reduces ductility. Manganese content is similar (0.60% max), but DC01 has stricter phosphorus (max 0.045%) and sulfur (max 0.045%) controls, improving cold forming performance. For applications requiring deep drawing, DC01 typically outperforms SPCC due to its higher elongation (28% vs 26% minimum).
SPCC (JIS G3141) Specifications
- Carbon: ≤0.15%
- Manganese: ≤0.60%
- Phosphorus: ≤0.100%
- Sulfur: ≤0.050%
- Tensile Strength: 270–410 MPa
- Yield Strength: 170–280 MPa
- Elongation: ≥26% (thickness dependent)
DC01 (EN 10130) Specifications
- Carbon: ≤0.12%
- Manganese: ≤0.60%
- Phosphorus: ≤0.045%
- Sulfur: ≤0.045%
- Tensile Strength: 270–410 MPa
- Yield Strength: 140–280 MPa
- Elongation: ≥28% (thickness dependent)
These differences directly impact downstream processing. For example, when forming automotive brackets, DC01’s lower yield strength reduces springback, while SPCC’s higher carbon content provides better wear resistance for sliding components. Both grades can be further processed into PPGI coil or GI coil after galvanizing, but the base material selection affects coating adhesion. ChinaCNU Steel offers pre-treatment recommendations for clients converting cold rolled coils into galvanized steel coil products.
Surface Finish and Dimensional Tolerances
SPCC is available in three surface finishes: commercial (No. 3), drawing (No. 4), and deep drawing (No. 5). DC01 follows EN 10130 with finishes A (unpolished), B (polished), and C (extra polished). For exposed automotive panels, DC01 finish C provides superior surface quality with Ra ≤ 0.6 µm. SPCC No. 5 is comparable but may show slight roller marks. Both grades meet EN 10131 thickness tolerances, but SPCC allows ±0.05mm variation for 1.0mm sheet, while DC01 holds ±0.04mm under the same standard.
When ordering SPCC vs DC01 cold rolled steel coil, buyers should specify surface roughness requirements. ChinaCNU Steel uses laser profilometers to verify Ra values before shipment. For clients producing PPGI coil, we recommend DC01 for its consistent surface energy, which improves paint adhesion. Our quality control team checks each coil for edge defects and oil film uniformity, critical for stamping operations.
Pricing and Availability Comparison
Market prices fluctuate, but DC01 typically commands a 3–5% premium over SPCC due to stricter European standards. For bulk orders exceeding MOQ 25 tons, ChinaCNU Steel offers competitive FOB pricing from Tianjin Xingang port. Below is a typical comparison for 1.0mm x 1250mm coils:
| Parameter | SPCC (JIS G3141) | DC01 (EN 10130) |
|---|---|---|
| Carbon Content (%) | ≤0.15 | ≤0.12 |
| Yield Strength (MPa) | 170–280 | 140–280 |
| Elongation (%) | ≥26 | ≥28 |
| Surface Finish Options | No. 3, 4, 5 | A, B, C |
| Typical FOB Price (USD/ton) | $680–$720 | $710–$760 |
| Lead Time (weeks) | 3–4 | 4–5 |
| Certification | JIS G3141 | EN 10130 |
Prices are based on 2026 Q1 market data for 25-ton orders, FOB Tianjin. ChinaCNU Steel provides volume discounts for orders exceeding 100 tons, with mixed container options available. For clients requiring galvanized steel coil or GI coil, we offer conversion services with hot-dip galvanizing at our partner facility, adding 7–10 days to lead time.
Industrial Applications and Grade Selection
SPCC dominates the Asian automotive aftermarket for non-structural parts like oil pans, brackets, and interior trim. DC01 is preferred in European-designed appliances (washing machines, refrigerators) due to its consistent forming behavior. For construction applications like roofing sheets or PPGI coil substrates, both grades perform similarly, but DC01’s lower sulfur content reduces weld porosity in automated lines.
ChinaCNU Steel’s technical team assists with grade selection based on forming severity. For simple bending (radius > 2x thickness), SPCC is cost-effective. For complex deep drawing (height > 3x diameter), DC01 reduces cracking risk. We also supply SPCD (deep drawing) and DC03/DC04 for extreme forming, with MOQ 25 tons for all grades. Our 15+ years of export experience ensures documentation matches destination country requirements—whether JIS for Japan or EN for Europe.
Quality Assurance and Certification
Third-party inspections by SGS or Bureau Veritas are available at client cost. ChinaCNU Steel maintains a 98.5% on-time delivery rate for 2026, supported by our factory in Boxing, Binzhou’s 200,000-ton annual capacity. We recommend requesting a material test certificate (MTC) before shipment to verify compliance with your specifications.
Frequently Asked Questions
- Can SPCC replace DC01 in European applications?
Yes, for non-critical parts, but DC01 is mandatory for products requiring CE marking. SPCC may fail EN 10130 elongation requirements for deep drawing. - What is the MOQ for cold rolled steel coils at ChinaCNU Steel?
Our standard MOQ is 25 tons per grade and thickness. Mixed containers (e.g., SPCC + DC01) are available for orders above 50 tons. - How does FOB pricing from Qingdao compare to other Chinese ports?
Qingdao offers lower inland freight costs for northern Chinese mills. Our FOB prices are typically 2–3% below Shanghai port due to shorter trucking distances. - Are SPCC and DC01 suitable for PPGI coil production?
Both work well, but DC01 provides better paint adhesion due to tighter surface roughness control. We recommend DC01 for high-gloss PPGI applications. - Certificate records — Review the certificate holder, scope and current verification status. Confirm the documents applicable to your order.
