Cold Rolled Steel Sheet, Cold Rolled Steel Plate

Release date: 2014-7-1

Product detailed

Our cold rolled steel sheet or plate employs hot rolled steel coil as raw material, and is formed through multi-step cold rolling. It has smooth and clean surface which is superior to that of hot rolled steel. Also, it features easy formability, and delivers outstanding mechanical property after heat treatment.

Our cold rolled plates and sheets are widely used in the manufacture of automobiles, aviation products, electrical products, industrial equipment, building material, precision instrument, food container, etc.

1. Superior workability

The cold rolled steel sheet or plate can be processed with different protective coatings to enhance its performance in anti-rusting. Hence, it is a commonly used as the substrate for galvalume steel sheets, galvanized steel plate, etc.

Because of our modern facilities and innovative technologies, our cold rolled plate has minimal deviation in mechanical properties.

2. Wide range of sizes
Our cold rolled steel plate or sheet is available with customizable sizes.

3. Wide range of material grades
By using different types of steel material, we can supply cold rolled carbon steel sheet, commercial quality cold rolled steel, products supporting stamping and deep drawing processes, and more varieties to suit specific application demands.

Available material grades are: Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, etc.

According to the different manufacturing demands, the cold rolled steel sheet or plate is classified into the General Purpose Type, Stamping Level, Deep Drawing Level, and the Ultra-deep Drawing Level.

The general purpose type is typically made of carbon structural steel or high-strength low-alloy structural steel, and undergoes strict performance tests. It has fine surface quality and supports stamping.

Our general purpose cold rolled steel plates are most often found in automobile and galvanized steel plate manufacturing field.

Technological Process
Our range of cold rolled steel is manufactured through processes such as descaling, cold rolling, annealing, leveling, galvanizing, cutting, and packing. Descaling is the process of removing the surface oxide layer. The relevant methods are pickling, alkaline cleaning, and mechanical descaling, among which pickling is the most commonly used. Alkaline cleaning is appropriate for special steel. Prior to pickling, the steel sheet should be welded or continuously annealed. After Pickling, it should be cleaned, dried, cut, and then packed. The frequently used pickling methods are continuous pickling, and push-pull type pickling.
