What it is
Cold-rolled coil (CRC) is HRC further rolled cold for a smoother surface, tighter thickness tolerance, and better formability. It is used where surface finish matters — appliances, furniture, automotive panels — so surface class and temper are as important as grade.
Grades & standards buyers order
| Grade | Standard | Notes |
|---|---|---|
| SPCC / SPCD / SPCE | JIS G3141 | Commercial, drawing, and deep-drawing grades — the difference is formability. |
| DC01–DC06 | EN 10130 | European cold-forming grades, increasing in formability. |
| Q195 / Q215 | GB | Chinese commercial grades. |
How it's sold: Sold by metric ton in coils, thickness ~0.3mm–3mm. Confirm surface class (matte/bright), oiling, and temper/hardness.
What drives the price
- HRC feedstock cost plus cold-rolling conversion
- Thickness (thinner = more expensive per ton)
- Surface class and formability grade
- Oiling and edge protection for transit
Lock these into the contract before you pay
Formability grade (SPCC vs SPCD vs SPCE)
Ordering SPCC when your press needs SPCE causes cracking — the grades look identical on paper.
Surface class and oiling
Wrong surface or missing oil film means rust or reject on arrival.
Temper / hardness
Over-hard temper fails forming; specify it explicitly.
Scams most common to cr coil
Grade Substitution (lower grade shipped than ordered)
Commercial SPCC shipped for a deep-drawing order — only found when parts crack in the press.
Bait-and-Switch Quality
A pristine sample coil followed by production coils with surface defects.
Forged Mill Test Certificates (MTC / EN 10204 3.1)
Temper and surface class on paper that the shipped coil does not meet.
Red flags in a quote or sample
- Formability grade not specified or downgraded silently
- No surface class or oiling detail in the quote
- Sample far better than the production description
Already paid and something's wrong?
If you received off-spec cr coil, a certificate that doesn't match, or your supplier has gone quiet after a deposit, move quickly. Recovery odds drop with every day that passes on a wire transfer.
Buying cr coil from China: FAQ
What grades of cr coil can I buy from China?
The most commonly ordered grades are SPCC / SPCD / SPCE, DC01–DC06, Q195 / Q215. Always pair the grade with its standard on the purchase order so the mill test certificate can be matched to what you actually receive.
What is the most common scam when buying cr coil from China?
Grade Substitution (lower grade shipped than ordered). For this product specifically: Commercial SPCC shipped for a deep-drawing order — only found when parts crack in the press. The defense is to specify the exact grade and standard, require a verifiable mill test certificate, and commission independent pre-shipment inspection.
What should I check before paying for cr coil?
Lock down formability grade (spcc vs spcd vs spce), surface class and oiling, temper / hardness in the contract, verify the supplier is a real manufacturer, and never release the balance until an independent inspection confirms the goods.
I already paid a Chinese supplier for cr coil — what now?
Act fast: contact your bank about a recall on the wire, gather all contracts and communications, report the pattern so others are warned, and review the documented cases to understand your options. The sooner you act on a redirected or disappeared payment, the better the odds.
