What is cold rolled steel plate?

Cold-rolled steel plate is a new product that is further cold-pressed by hot-rolled steel plate. Because it has undergone multiple cold rolling processes, its surface quality is better than that of hot-rolled plates. After heat treatment, its mechanical properties have also been significantly improved. Widely used in automobiles, construction, home appliances, industrial equipment and other fields.

Characteristics of cold rolled steel plates

Excellent surface quality: The cold-rolled steel plate has been rolled and straightened multiple times during the cold rolling process, and has high surface flatness, no obvious surface defects and wrinkles, and better surface quality.

High dimensional accuracy: Using advanced rolling mills and control technology during the cold rolling process, high dimensional accuracy, good dimensional stability, and small tolerances in thickness and width can be obtained.

Superior mechanical properties: The grain structure of cold-rolled steel plates is smaller, and its mechanical properties such as yield strength, tensile strength, elongation and impact toughness are all better.

Good processing performance: Since the size and performance of cold-rolled steel plates are relatively stable, it is easy to control during the processing and is easy to perform cutting, welding, forming and other processing techniques.

Wide range of sheet thickness: Cold-rolled steel plates can produce thinner sheets, with thicknesses ranging from a few hundredths of millimeters to several millimeters, suitable for the needs of different fields.

Various surface treatments: Cold-rolled steel plates can be processed through different surface treatments, such as galvanizing, coating, polishing, etc., to increase their anti-corrosion, aesthetics and other properties.

Good corrosion resistance: Cold-rolled steel plates contain high alloying elements, which make them have good corrosion resistance and are suitable for use in some special environments and conditions.

Environmental protection: Cold-rolled steel plates do not require high-temperature operations during the production process. Compared with hot-rolled steel plates, they can better reduce energy consumption and environmental pollution.
