cr coil sheet
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.

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) |
