Product Specification and Steel Grade (For Reference)

Available Size

Cold-rolled steel coils have good properties, and cold-rolled strips and steel sheets with thinner thickness and higher precision can be obtained by cold-rolling. High flatness, high surface finish, clean and bright surface of cold-rolled sheet. It is easy to be coated and processed and has the characteristics of high stamping performance and low yield point, so cold-rolled steel coil has a wide range of uses, mainly used in automobiles and building materials.

Applications of Cold Rolled Steel

Cold rolled steel is often used for applications that require tighter tolerances and better surface finishes. Typical parts and products include:

· Aerospace structures

· Home appliances

· Metal furniture

· Strips, rods, bars, and sheets

· Mechanical Components

Cold rolled steel

While hot rolled steel is heated then cooled, cold rolled steel is heated and cooled at the room temperature and then rolled after again. The steel is processed further in cold reduction mills, where the material is cooled (at the room temperature) followed by forming the material by either press-braking or cold roll forming to achieve the desired shape.

The term “rolled” is often used just to describe a range of finishing processes such as turning, grinding, and polishing, each of which modifies existing hot rolled stock into a more refined product. Technically, “cold rolled” applies only to sheets that undergo compression between rollers. But forms like bars or tubes are “drawn” not rolled. Hot rolled bars and tubes once cooled, are processed into what we call “cold finished” tubes and bars.

Cold Rolled Steel Coil Supplier

Cold-rolled steel is low-carbon hot-rolled steel that has been rolled at room temperature, below its recrystallization temperature. The steel is then cleaned of oxide scale and finished in a specific series of rolling to just over the desired thickness, heating to controlled temperatures, and final rolling to the desired thickness. This produces steel with a close thickness tolerance (+/-.0015” or better) and a wide range of controlled surface finishes. The process of cold rolling increasing the steel’s strength and hardness, while decreasing its ductility. Not only can you achieve improved mechanical properties, cold rolling provides more control over the shape and final dimensions of the product.

Use cold-rolled steel where thickness tolerances and surface conditions have a narrow window for success in your application. As a cold rolled steel coil supplier, we will be glad to help you select the exact grade for your specific needs.
