DC01 Q235A Cold-rolled coils carbon steel Coil
Superior Surface Quality – Cold-rolled coils feature smooth surfaces with high finish, free from pitting and oxide scale defects common in hot rolling.
High Dimensional Accuracy – Ensures precise thickness and measurements, meeting strict industrial standards.
Excellent Performance Options – Offers tailored properties such as electromagnetic characteristics and deep drawing capability for specialized applications.
Reliable Grade Availability – Produced in widely used grades including SPCC, SPCD, SPCE, ST12-15, and DC01-06 to suit diverse needs.
Cold-rolled coils are produced by rolling hot-rolled coils below the recrystallization temperature. Since there is no heating in the production process, there are no defects such as pitting and iron oxide scale that often occur in hot rolling, and the surface quality is good and the finish is high. The dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc. Commonly used grades are: SPCC; SPCD; SPCE; ST12-15; DC01-06.
Commonly used national standard numbers for cold-rolled coils:
Common grades of cold rolled coils: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-061

Characteristics of cold rolled steel coils
1. Material
①Carbon steel (different grades such as CQ, DQ, DDQ, EDDQ, etc.)
②Alloy steel (HSLA, high-strength steel, ultra-high-strength steel, etc.)
There are many materials of cold-rolled sheet, but its classification can basically be classified into two categories: carbon steel and alloy steel according to the two major characteristics of chemical composition and mechanical properties.
2. Features
①Good surface quality and good stamping performance, so it can be widely used in the automotive industry, food cans, aerospace, precision instruments and many other fields.
② With good heat resistance, the cold-rolled sheet processed by the rolling process is generally more heat-resistant than the ordinary sheet.
③It has good heat reflectivity. Cold-rolled steel processed by processing technology under normal temperature crystallization has stable surface properties, and can emit heat well under the condition of heating to protect the plate.
Carbon steel coils are widely used in manufacturing industries such as ships, automobiles, bridges, buildings, machinery, and pressure vessels.
