Cold rolled coil is a product made from hot rolled coil as raw material and rolled at room temperature below the recrystallization temperature.

Cold rolled coil is a product made from hot rolled coil as raw material and rolled at room temperature below the recrystallization temperature. Due to its advantages of good surface quality, high dimensional accuracy, high strength, etc., it is widely used in the following fields:
◣ Automobile manufacturing
Structural body parts: Cold rolled coils are usually used for automobile body frames, doors, engine hatches and other parts. Cold rolled coils have good molding and strength, and can meet the processing requirements of complex shapes of automobile body, while ensuring the safety and stability of the body.
Automotive components: engine block, cylinder head, transmission housing and other components will also use cold rolled coil. These parts require high precision dimensions and good surface quality to ensure the normal operation of the engine and transmission.
◣ Home appliance industry
Refrigerator: Cold rolled coils are often used for the shell, liner, shelves and other parts of refrigerators. Cold rolled coils have a smooth, corrosion-resistant surface that meets the refrigerator's requirements for appearance and service life.
Air conditioners: Cold rolled coils are also used for the outer shell of the outdoor unit, the evaporator and condenser of the indoor unit, and other parts of the air conditioner. The high strength and good molding properties of cold rolled coils enable them to adapt to the complex shapes and structural requirements of air conditioning components.
Washing Machines: Cold rolled coils are usually used for the inner and outer tubes of washing machines. Cold rolled coils have good corrosion and abrasion resistance, which can ensure that the washing machine will not rust and wear in the long-term use of the process.
◣ Construction
Roofing and walling: Cold rolled coils are used to make roofing and walling profiles in some lightweight steel buildings. This kind of pressed steel plate has the advantages of light weight, high strength and good waterproof performance, which can improve the overall performance of the building.
Building decoration: Cold rolled coils can be processed into various shapes of decorative lines, door and window frames, etc., which are used for indoor and outdoor decoration of buildings. Its surface can be subject to various treatments, such as spraying and plating, to meet different decorative needs.
◣ Electronic Equipment
Computer chassis: The shell of computer chassis usually adopts cold rolled coil. Cold rolled coil has good strength and electromagnetic shielding performance, can protect the computer's internal electronic components from external electromagnetic interference, while ensuring the stability and safety of the chassis.
Cell phone shell: some high-end cell phone shell will also use cold rolled coil. Cold rolled coil after precision processing and surface treatment, can be made of high strength, light and thin, beautiful cell phone shell.
◣ Other fields
Hardware products: such as furniture hinges, handles, locks and other hardware accessories, usually use cold rolled coil. The good molding and surface quality of cold rolled coils can meet the requirements of hardware products for precision and appearance.
Packaging industry: some high-grade boxes, cans and other packaging containers will also use cold rolled coil. Cold rolled coils can be processed into various shapes of packaging containers through stamping, stretching and other processes, with good sealing and aesthetic properties.
