Cold-rolled steel
DC01, DC02, DC03, DC04, DC05, DC06 are standardized European cold-rolled low-carbon steels specified in EN 10130 for parts that require very good formability and consistent surface quality. For general structural press-formed components, DC03–DC06 are the common choices; DC01 and DC02 are suitable when slightly higher strength or different deoxidation practice is acceptable. For buyers seeking competitive supply from China, GNEE STEEL offers factory-direct pricing, fast stock delivery, and test documents to meet EN 10130 requirements. When selecting a grade, prioritize the target forming severity, required surface finish (A or B), and whether a coated (galvanized) product under EN 10152 is needed.

Welding, cutting, forming & secondary operations
Cutting: laser, shearing, plasma - standard procedures apply; burr control needed for thin gauges.
Forming: springback depends on yield and thickness; DC05–DC06 show best r-values and lower springback for deep draws. Use controlled lubrication for complex draws.
Welding: standard MIG/MAG and resistance spot welding work well. For galvanized variants check for zinc fume mitigation and adjust welding parameters. Request the mill's welding recommendations when accepting coated surfaces.
We are manufacturer of steel products. We have quality steel coils and sheets for sale. Except for GI coils and sheets, we also have GL, PPGI, PPGL, Corrugated sheet, etc. to choose from. The standard seaworthy package contains waterproof kraft paper and plastic film inside, and steel sheets outside, then bound with steel strips. To secure it during transportation, we use wood pallets. During the two decades, we have developed complete systems from pre-sales consulting to after-sales service.

FAQ
1.Can DC grades be supplied with higher strength?
Some can be supplied as alloyed steels (e.g., with small additions of B or Ti) by agreement with the purchaser; specify when ordering.
2.What certificates should I request?
Typical: mill test certificate (EN 10204 2.1) or specific 3.1/3.2 documents for higher assurance. State required certificate at enquiry.
3.Is DC06 the same across all mills?
The EN limit is fixed, but some producers provide enhanced DC06 variants (e.g., SSAB Form 06) with tighter guarantees for r-value and surface finish. Compare the supplier's technical datasheet.
4.How do I minimise stretcher marks?
Choose skin-passed products, control lubrication during forming and avoid excessive storage after skin-pass. EN 10130 lists skin-pass recommendations and validity timelines.
