COLD ROLLED COIL
PRODUCT DESCRIPTION
Cold Rolled Coil (CRC), also known as Cold Rolled Full Hard (CRFH), is a cold-rolled steel sheet that has not been annealed. It is a semi-finished steel product with high hardness and high strength.
I. Production Process
Using hot-rolled coils as raw material, the process involves pickling → cold rolling (high-intensity rolling at room temperature) → direct coiling without annealing or softening treatment.
II. Core Characteristics
Extremely high strength: Cold work hardening significantly increases yield strength and tensile strength.
High hardness: Hard surface, good wear resistance.
Poor plasticity, brittle: Low elongation, prone to cracking during bending and stamping.
Smooth surface: No iron oxide scale, high flatness and dimensional accuracy.
Relatively stiff sheet shape: High springback, difficult to level.
III. Common Specifications
Thickness: 0.15–2.5 mm (mainstream 0.3–1.5 mm)
Width: 750–1650 mm
Coil inner diameter: 508 mm / 610 mm
Material: SPCC, DC01, Q195, Q235B Low-carbon steel, etc.
IV. Main Uses
As a substrate for deep processing (not directly used for complex forming)
Galvanized substrate: The main raw material for hot-dip galvanized (GI), aluminum-zinc (GL), and zinc-aluminum-magnesium (ZM) coatings
Color-coated substrate: Used for architectural color-coated sheets (PPGI/PPGL)
Simple forming parts:
Construction: Floor decking, fencing, corrugated sheets
Hardware: Cable trays, cabinets, simple stamped parts
Packaging: Steel strips, iron drums, metal boxes
