Cold-rolled Plates & Coils

ZC's cold-rolled products facility has an annual capacity of 2.6 million tons, equipped with pickling, continuous annealing, silicon steel, zinc/aluminium coating, and tin coating lines supplied by SIEMAG, CMI, and TMEIC. Main products — coated strip, galvanized strip, non-oriented silicon strip, annealed strip, cold-rolled coil, and hot-rolled pickled coil — serve automotive structures, household appliances, construction, food and beverage packaging, and electrical steel applications.

Applications

→ Automotive structures — body panels, chassis components, and reinforcement members
→ Household appliances — outer panels and structural parts for white goods
→ Construction steel — profiles, purlins, and cladding sheets
→ Food and beverage packaging — tin-coated strip for can manufacturing
→ Electrical steel — non-oriented silicon strip for motor cores and transformers

Specifications & Delivery Conditions

Surface Finish & Delivery Condition

Condition	Description	Typical Grades
2D (full hard)	As-cold-rolled — matte surface, high hardness; not for deep drawing	DC01, SPCC
2B (annealed)	Continuous annealed and skin-passed — smooth, semi-bright; most common delivery	DC01–DC06, BH grades
BA (bright anneal)	Annealed in controlled atmosphere — mirror-bright; no pickling marks	DC04, DC05, DC06
Skin-passed (SP)	Light temper pass on annealed coil — improved flatness, suppressed yield-point elongation	DC01–DC04, BH grades
GI / GL (hot-dip galvanised)	Zinc or Zn-Al alloy coated — minimum 100–275 g/m² coating weight	DX51D, DX53D, DX54D
EG (electrogalvanised)	Electrolytic zinc coating — thin, uniform; excellent paintability	DC01-EG, automotive grades
Tin-coated (ETP/TFS)	Electrolytic tin or tin-free steel for food-grade packaging	T1–T5, DR8, TFS
Non-oriented silicon (CRNO)	Insulated silicon steel for motor cores and small transformers	W470–50A, W600–50A
