Product Introduction

CR Coil Sheet refers to Cold Rolled Coil Sheet, a type of steel product that is manufactured by cold rolling hot-rolled coils. Cold rolling improves the surface finish, dimensional accuracy, and mechanical properties of the steel.

Production Processes

CR Coil Sheets are versatile, high-quality steel products suitable for a wide range of applications. Their excellent surface finish, dimensional accuracy, and mechanical properties make them a preferred choice in industries like automotive, appliances, and construction.

Cold-Rolled Steel Coil Grades by Standard

Standard (GB)	Standard (JIS)	Standard (EN)	Standard (ASTM)	Usage	Characteristics
SPCC, DC01	SPCC	DC01	A1008	General Purpose	Standard cold-rolled sheet, suitable for basic stamping and forming.
SPCD, DC03	SPCD	DC03	A1009	Stamping Purpose	Enhanced formability for moderate stamping and forming (e.g., automotive panels)
SPCE, DC04	SPCE	DC04	-	Deep Drawing Purpose	Excellent ductility and formability for deep-drawn parts (e.g., fuel tanks, containers).
-	-	DC05	-	Extra Deep Drawing	Superior stretchability for highly complex shapes (e.g., precision automotive components).
SIZE: Thickness:0.2mm-3mm, Width: 600mm-2000mm

Surface Treatment Options

Surface Treatment	Description
Oiled	Coated with a thin layer of oil to prevent rust during storage and transportation.
Passivated	Treated with a chemical solution to enhance corrosion resistance.
Phosphated	Coated with a phosphate layer for improved paint adhesion.
Galvanized	Coated with zinc for enhanced corrosion resistance (not typical for CR coils but can be requested).
·Oiled/Passivated: Suitable for scenes with general anti-rust requirements (such as warehousing and transportation). ·Phosphated: Parts that require subsequent spraying (such as automobile body panels). ·Galvanized: Customized requirements in highly corrosive environments (such as outdoor structural parts)

Advantages of CR Coil Sheets

Advantage	Description
Superior Surface Finish	Smooth and free from scale, ideal for painting or coating.
High Dimensional Accuracy	Tight thickness and width tolerances.
Improved Mechanical Properties	Higher strength and hardness compared to hot-rolled sheets.
Formability	Excellent for deep drawing, bending, and stamping.
Consistency	Uniform properties across the entire coil.
