Product Description
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. Shanqi Steel produces various specifications of cold-rolled coils, hot-rolled coils, carbon steel pipes, carbon steel bars, steel bars and other high-quality products.

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.
