Cold Rolled Carbon Steel Coil is manufactured through a cold rolling process that provides excellent dimensional accuracy, smooth surface finish, and consistent mechanical properties. Compared with hot rolled steel, it offers tighter thickness tolerances, improved formability, and superior surface quality, making it ideal for precision manufacturing applications.
Widely used in automotive components, home appliances, electrical equipment, metal furniture, and industrial fabrication where high-quality surface finish and precise dimensions are required.
Cold rolled carbon steel coil (high-precision SPCC cold rolled steel coil, DC01/DC03/DC04 deep drawing steel coil, ST12 commercial quality steel coil, SAE 1008/1010 CRC strip coil, and full hard cold rolled steel master coil) is manufactured by continuous cold reduction of pickled hot rolled steel coils at ambient temperatures, followed by bright hydrogen annealing, precision tension leveling, and skin-pass temper rolling. Engineered for high-speed automated progressive stamping, deep drawing vehicle bodies, home appliance cabinets, and precision steel pipe manufacturing, cold rolled carbon steel coil offers superior surface finish, tight thickness tolerances, flawless edge straightness, and exceptional mechanical formability.
At XQJ Metal, we operate state-of-the-art 4-stand tandem cold rolling mills, continuous annealing lines, high-speed strip slitting lines, and automated tension levelers to produce world-class cold rolled carbon steel coil products conforming strictly to global engineering standards, including ASTM A1008 (cold-rolled carbon steel sheet & strip coil), EN 10130 (cold rolled low carbon steel flat products), JIS G3141 (SPCC/SPCD/SPCE), and DIN 1623 specifications. We supply full coil thickness options from 0.2mm to 3.5mm, widths up to 1500mm, coil inner diameters (ID 508mm/610mm), and custom narrow slitting coil strips down to 20mm in Matte/Dull (SD), Bright (SB), and Oiled rust-inhibited surface finishes.

Q1: What is the difference between SPCC and DC01 cold rolled carbon steel coil?
A: SPCC is defined under Japanese industrial standards (JIS G3141), while DC01 is defined under European standards (EN 10130). Both represent standard commercial quality cold rolled steel suitable for basic forming, bending, and welding, with equivalent chemical and mechanical performance.
Q2: Can XQJ Metal supply custom slit cold rolled steel coils with smooth rounded mill edges?
A: Yes, our high-speed precision slitting lines can furnish slit coils with deburred edges or rolled round safety edges tailored for roll-forming and continuous stamping operations.

Cold rolled carbon steel coil offers a smoother surface finish, tighter dimensional tolerances, and better formability than hot rolled steel coil. Hot rolled coil is generally preferred for heavy structural applications, while cold rolled coil is widely used for precision fabrication and surface-critical products.
The cold rolling process enhances surface finish, dimensional accuracy, and thickness consistency, making the material well suited for applications that require precision forming, coating, or further fabrication.
Cold rolled carbon steel coil is widely used for stamping, roll forming, bending, laser cutting, and coated steel production. Its consistent quality and excellent formability help improve manufacturing efficiency and finished product accuracy.
It offers excellent resistance to seawater corrosion and maintains strength in humid and salt-rich conditions.
No. Strength is achieved through strain hardening rather than heat treatment.
Yes. It provides excellent weldability for structural fabrication.
Yes, it is commonly applied in tanks and pressure equipment.
Yes. It provides higher strength compared with most non-heat-treated aluminum alloys.
Yes. Thickness, width and temper can be adjusted based on project demand.
