Cold Rolled Steel Coil & Processing Solutions
Cold rolled steel coil (CR coil) is an essential industrial raw material manufactured by cold-reducing hot-rolled pickled strip below recrystallization temperature, followed by annealing and temper rolling. Offering superior surface smoothness, precise thickness tolerances, high yield strength, and excellent formability, cold rolled coils provide the ideal substrate for precision roll forming, metal stamping, automotive components, and electrical appliances. Available in commercial, drawing, and structural steel grades, our cold rolled coils ensure consistent cross-sectional accuracy and uniform mechanical properties across high-speed continuous production lines.

About Cold Rolled Steel Coil & Processing Solutions
Cold rolled steel coils (CR coils) represent the benchmark of dimensional accuracy and aesthetic surface finish in flat steel manufacturing. Produced through advanced multi-stand tandem cold reduction mills, the steel strip undergoes significant plastic deformation that refines grain structure and imparts tight gauge tolerances typically within ±0.015 mm.
Following cold reduction, the coils undergo batch annealing or continuous annealing (CA) in a protective hydrogen-nitrogen atmosphere to restore ductility and relieve internal crystal stresses. A subsequent skin-pass temper mill run eliminates stretcher strain fluting, optimizes surface roughness (yielding matte, bright, or commercial finishes), and enhances strip flatness with zero camber or coil curvature.
In roll forming and metal forming applications, cold rolled steel delivers exceptional bendability and consistent springback behavior, critical for manufacturing tight-radius structural sections, architectural wall cassettes, and automotive reinforcements. Our coils conform strictly to international specifications including EN 10130 (DC01, DC03, DC04), ASTM A1008 (CS Type B, DS, DDS), and JIS G3141 (SPCC, SPCD, SPCE). Available slit strips and master coils are supplied with customized light electrostatic rust-preventive oiling or dry passivated finishes, wrapped in heavy-duty multi-layer waterproof vapor-barrier packaging for long-distance maritime export.

FAQ
What is the primary difference between cold rolled (CR) and hot rolled (HR) steel coil?
Hot rolled steel is rolled at high temperatures above recrystallization (resulting in mill scale and looser tolerances), whereas cold rolled steel is processed at ambient temperatures after pickling, delivering tighter thickness tolerances (±0.015 mm), smooth mill-scale-free surfaces, and higher yield strength.
Which steel grades are standard for roll forming and precision stamping?
Standard grades include commercial quality SPCC / DC01 / ASTM A1008 CS Type B for general bending, and deep-drawing quality SPCD / SPCE / DC03 / DC04 for intricate roll forming profiles and deep-drawn metal stampings.
What surface finishes and roughness levels are available?
We supply standard Matte Finish (Ra 0.6–1.9 µm) ideal for paint adhesion and roll forming, Bright Finish (Ra < 0.4 µm) for decorative plating, and Rough Finish (Ra > 1.9 µm) for specialized friction applications.
How are cold rolled steel coils protected against corrosion during ocean transit?
Coils are coated with light or medium electrostatic rust-preventive oil (DOS/mineral oil) and wrapped in multi-layer VCI anti-rust paper, polyethylene woven plastic, steel inner/outer edge protectors, and circumferential steel straps on fumigated pallets.
Can coils be slit to custom narrow strip widths before shipment?
Yes, our processing lines provide precision slitting from 20 mm up to 1500 mm wide with tight width tolerances within ±0.1 mm, complete with deburred edges and custom inner diameters (508 mm or 610 mm).
What thickness and width range do you supply?
Standard thickness ranges from 0.20 mm to 3.00 mm, with master coil widths ranging from 600 mm to 1500 mm. Slit strips are tailored to exact customer production specifications.
What mill test certificates and compliance documentation accompany shipments?
Every coil delivery is accompanied by an EN 10204 Type 3.1 Mill Test Certificate (MTC) detailing complete chemical ladle analysis, yield strength, tensile strength, elongation percentage, and Erichsen cupping test values.
