PRODUCT DESCRIPTION
When you thread a fresh coil and the press line quiets to a steady hush—that’s the payoff of a clean SPCC/SPCD substrate. The sheet surface is cool and glass-smooth to the touch, sliding across rollers without chatter. Low-carbon chemistry and controlled cold reduction give you generous bending angles and stable draws; burrs stay minimal, edges feel tight, and the paint-class finish holds e-coat and powder without fish-eyes. DOS oiling prevents fingerprinting during long handling windows. If you chase high OEE, this is the steel that keeps dies clean, setup time short, and scrap predictable. It’s the substrate you spec when downtime costs more than steel.

Operational certainty — Tight thickness/flatness and stable elongation bands reduce shimming time, keep takt stable, and protect tooling.
Forming headroom — Choose SPCC for bending/general forming, SPCD for drawing, SPCE for deep-draws; match grade to draw depth instead of over-spec’ing more expensive substrates.
Paint-class surfaces — Micro-roughness supports phosphating/e-coat/powder; fewer surface defects means less rework.
Line-friendly supply — 508/610 mm IDs, standard widths, oiled/non-oiled packaging and skin-pass temper to feed most decoilers with minimal changeover.
Grade selection quick table
| JIS | Typical purpose | EN (10130) |

| SPCC | Bending & simple forming | DC01 |
| SPCD | Drawing | DC03 |
| SPCE | Deep drawing | DC04 |
Standards & grade families: JIS SPCC/SPCD/SPCE with EN DC01–DC04 and DIN ST12–ST14 equivalents for cross-reference.
Size window: CR 0.12–6.0 mm common; widths to 1500 mm; coil ID 508/610 mm; coil 3–13 t typical.
Surface/temper: oiled / non-oiled / DOS; skin-pass; soft–full hard tempers for draw control.
Tolerances: examples show ±0.02 mm thickness/width on narrow gauges; tight flatness for CTL.
Processing services: slitting, CTL, decoiling, bending, punching, annealing; ports Tianjin/Qingdao/Shanghai for export.
Commercials: MOQ 3–25 t (commodity listings), lead time ~7–30 days; market context ~USD 500–700/t for CR coil depending on spec & lanes.
Lower unplanned stops: predictable forming behavior cuts split-line surprises and die clean-ups.
Faster changeovers: consistent gauge + skin-pass temper = fewer test pulls before rate-up.
Cleaner cosmetics: DOS oil + smooth surface reduce fingerprints and micro-abrasion during WIP handling, supporting Class-A paint specs.
Audit-ready: lot traceability, chemistry & tensile reports available, aligned with JIS 3141 and buyer PPAP-style reviews.
Small paragraph: From mill to component, we minimize hand-offs. Coils arrive press-ready or sheeted to your takt. For fabricators, we tailor temper, oiling, and slit edges to your downstream equipment.
Cutting & slitting: tight slit-edge/burr control for laser & CNC.
Decoiling/CTL: flatness tuned for e-coat lines; sheet lengths per jig.
Forming advisory: grade/temper pairing for draw ratio & springback.
Surface prep: non-oiled / oiled / DOS; skin-pass; coating adhesion guidance.
QC artifacts: MTC 3.1, tensile/hardness/chemistry by lot; third-party inspection on request.
Small paragraph: Conformance and transparency reduce total landed risk. We align to public standards so your teams can validate fast.
Standard: supply against JIS G 3141 with dimensional/mechanical envelopes consistent with published tables.
Mechanical envelope: commercial-quality tensile ≥270 MPa typical; elongation increases with gauge; deep-draw grades carry higher r-values.
Documentation: heat-number traceability; inspection reports included with shipment; packaging per export spec for sea freight integrity.
Small paragraph: Built for export programs and repeat schedules.
Packing: seaworthy wraps, edge guards, steel straps; eye-to-sky / eye-to-wall as specified.
Handling: ID 508/610 mm fits mainstream decoilers & C-hooks.
Ports & lead time: typically Tianjin / Qingdao / Shanghai, 7–30 days depending on tonnage & processing.
Commercials: MOQ from 5 t on standard grades; T/T, L/C; consolidated loads available for mixed oiled/non-oiled.
Q1: How to choose SPCC vs. SPCD vs. SPCE?
Bending/shallow forming → SPCC; cup-type draws → SPCD; deep-draw & cosmetic panels → SPCE. We can mirror EN DC01–DC04 if your print uses EN 10130.
Q2: Can you mix oiled and non-oiled in one shipment?
Yes. We pack to prevent transit rub; DOS-oiled for press-ready lines, non-oiled for immediate coating.
Q3: What coil IDs and weights can you supply?
IDs 508/610 mm; coil weights typically 3–13 t from peer specs; our listing range is 2–20 t depending on spec.
Q4: What tolerance can I expect on thin gauges?
Competitor references show ±0.02 mm on thin materials; we quote to your drawing and align with JIS thickness/flatness tables.
Q5: What’s the current market band for CR coil?
Public supplier guidance shows ~USD 500–700/t subject to gauge/temper/lanes; we lock price on PO with validity windows.
