SPCC Cold Rolled Steel — Factory Direct Supplier | Huaxia-Steel
SPCC is the Japanese Industrial Standard (JIS G 3141) grade for cold rolled carbon steel sheets and coils. It is the commercial-quality workhorse for applications that need a smooth, dimensionally tight surface without the scale and roughness of hot rolled material. Huaxia-Steel supplies SPCC cold rolled steel in coils and cut sheets, with mill certificates and export packing suited to global buyers.
Product Overview
SPCC is a low-carbon rimmed or killed steel produced by cold reduction after hot rolling, then annealing and skin passing. The result is a clean, oiled surface with tight thickness tolerance, ideal for stamping, bending and painting. It is supplied as commercial quality (SPCC) and can be upgraded to drawing quality (SPCD, SPCE) when deeper forming is needed, giving buyers a clear upgrade path as part complexity grows.

Manufacturing Standards
SPCC conforms to JIS G 3141. Equivalent grades include ASTM A1008 (CS/DS) and EN 10130 (DC01). We can cross-reference to the standard your project requires and issue the matching mill certificate so your incoming inspection and customs paperwork line up with the order.
Applications
- Automotive body and structural parts
- Home appliances and enclosures
- Furniture and shelving
- Electrical cabinets
- General stamping and forming
- Painted or coated substrate
Quality Assurance
Every coil is inspected for thickness, surface, oiling and edge condition. Mill test certificates are provided, and third-party inspection (SGS, BV, TUV) can be arranged. Coils are wrapped in rust-proof paper and strapped for export, with coil ID and OD protected against transit damage.
Packaging and Shipping
SPCC coils are eye-to-wall or eye-to-sky packed with edge protection, inner and outer wrapping, and steel strapping. Sheets are bundled and palletized. We ship FOB, CIF or CFR to any major port with moisture protection for long voyages.
Surface Finish and Oiling
SPCC is supplied with a light anti-rust oil and either a matte or bright finish. The bright finish is preferred where appearance matters, while the matte finish welds and paints well. Specify oil type and quantity if your process requires low or no oil for direct painting or welding.
Thickness Tolerance and Flatness
JIS class A tolerance keeps thickness tight, which protects tool life in stamping and ensures consistent fit. Flatness is controlled during skin passing; for critical flat parts request a flatness class and we will sort or level accordingly before shipment.
Formability and Deep Drawing
For shallow stamping, SPCC is sufficient. For deep drawing (sink shells, automotive panels), step up to SPCD or SPCE, which have lower carbon and controlled grain to resist earing and splitting. Tell us the draw ratio and we will recommend the right sub-grade and temper.
Equivalent Grades Cross-Reference
| JIS | ASTM | EN | Use |
|---|---|---|---|
| SPCC | A1008 CS | DC01 | Commercial |
| SPCD | A1008 DS | DC03 | Drawing |
| SPCE | A1008 DDS | DC04 | Deep drawing |
Cross-referencing lets you substitute SPCC into a design written to ASTM or EN standards without re-qualifying the part, provided the mechanical and surface requirements match.
Coil Inner Diameter and Packaging Options
SPCC is commonly supplied on 508 mm or 610 mm ID coils, with eye-to-wall or eye-to-sky packing. The ID must match your decoiler; tell us your line spec so the coil runs without adaptation. Packaging includes rust-proof paper, inner and outer wrap, edge protectors and steel strapping, and we can add wooden spacers or pallets for sheet packs.
Storage and Rust Prevention
Keep coils dry and off the floor; the light anti-rust oil protects for a few months under cover but not for long outdoor storage. For tropical or long-transit routes, request extra oil or VCI wrap. Rotate stock by arrival date so older coils are used first and the oil film stays effective.
Cutting and Slitting Services
We supply slit widths, cut-to-length sheets and blanking to drawing, which reduces your scrap and downstream handling. Slitting keeps the bright edge; cut sheets are deburred on request. Send your width and tolerance and we return a coil or sheet pack ready for the press.
Typical Order Sizes and Lead Time
SPCC is available from stock for common gauges or made to order in 3-15 MT coils. Stock grades ship in 7-15 days; made-to-order runs take 25-40 days depending on the mill. MOQ for special width or temper is typically one coil, which keeps trial orders affordable.
Why Buy SPCC from a Direct Supplier
Buying close to the mill gives you a consistent surface, traceable certificates and a shorter supply chain. We bridge that with export packing, inspection and documentation so you get mill quality with trading-company service, and a single contact for grade, size and certificate questions.
SPCC vs Hot Rolled: When to Choose
Choose SPCC cold rolled when surface finish, thickness accuracy and paintability matter more than price. Choose hot rolled when strength and cost dominate and a rough surface is acceptable. For many enclosures and appliances, SPCC is worth the premium because it paints and stamps cleanly.
Common Defects and How to Avoid
Watch for coil edge rust, oil unevenness, waviness and scratches. Buy from a mill that controls oiling and packing, inspect at arrival, and reject coils with deep scratches or heavy edge rust. Storing under cover and using stock on a first-in basis avoids most problems.
Coil vs Sheet: Which to Order
Order coil when you have decoiling and blanking capacity and want the lowest unit cost. Order cut sheets when you want to skip processing or need tight flatness. We supply both, and can pre-cut to your blank size to reduce scrap.
Industries We Serve

SPCC Quality Plans and Inspection
We align every SPCC order to a simple quality plan: confirm thickness and width tolerance, surface and oiling, coil ID and packing, then verify on arrival with a tape, micrometer and visual check. For critical surface jobs we can add a coil-to-coil sample and keep the certificate tied to the coil number so any query traces back to the melt.
Working With a Direct Mill Supplier
Buying close to the mill gives consistent surface and chemistry, shorter lead time on stock, and a single accountable contact for grade, size and certificate. We act as that bridge for export buyers, handling packing, inspection and documentation so you get mill quality with trading-company service and no middle-layer confusion.
Sustainability and Compliance
SPCC is a commodity steel with a well-understood footprint. We can supply mill environmental statements on request and ensure packaging meets your destination’s requirements, including ISPM-15 for wooden components. If your tender scores sustainability, ask for the documentation early so it travels with the shipment.
Ordering SPCC: Tips for a Smooth Purchase
To order SPCC smoothly, confirm the gauge, width, coil ID, surface (matte or bright), oil level and packing before you ask for a quote, and state the standard (JIS G 3141) plus any equivalent you accept (ASTM A1008 or EN 10130). Share your end use so we can recommend the right sub-grade and temper, and confirm lead time for stock versus made-to-order.
Our Commitment to Export Buyers
We commit to traceable certificates, seaworthy packing and responsive documentation, and to holding your profile on file for fast, consistent reorders. For SPCC and other cold rolled grades, that means the coil you receive matches the sample and the certificate every time, which is what keeps your line running and your customers satisfied.
SPCC for Different Finishes
SPCC is supplied matte or bright, oiled or dry, depending on your process. Bright oiled suits visible or painted parts; matte welds and paints well for structural use. Tell us your downstream process so we supply the finish that saves you a pre-treatment step, and confirm oil type if your line needs low or no oil before coating.
Typical Project Flow With Us
A typical SPCC order runs from enquiry and grade confirmation, to sample or stock reservation, to mill or warehouse shipment with inspection and documents, to arrival and goods-in check. We keep you updated at each step and hold your specification on file, so reordering is a single message rather than a fresh qualification every time.
SPCC Summary and Next Step
SPCC is the sensible default cold rolled grade for appliances, enclosures, furniture and general stamping where surface and thickness accuracy matter. Tell us your gauge, width and finish, and we return a quoted, certified, export-packed coil or sheet ready for your line. Reach out for a sample or a stock check, and we will confirm lead time the same day.
