Cold Rolled Steel (CRS) sheets
Cold Rolled Steel (CRS) sheets are metal sheets processed at room temperature, typically below their recrystallization temperature, which increases strength by up to 20% and creates a smooth, precise finish. These sheets are used for applications requiring superior surface quality and tight tolerances, such as automotive panels, home appliances, and furniture.

Cold Rolled Steel Sheets
CR steel sheets have good processability, with good flatness and excellent surface, are available with different thickness and width combinations; Are mainly used to manufacture the high value-added products in automotive and appliance, beverage packaging, electronic, electrcial moor and building etc. The CR steel sheet include the uncoated steel steel, galvanzied steel sheet, tin plate and TFS, precoated steel sheet and electrical steel steel, etc.
Core Features: Basic cold rolled products with flat surface, high dimensional accuracy, medium plasticity, good processability and controllable cost, suitable for simple bending, stamping and cutting processing.
Specification Range: Thickness 0.3-3.0mm, Width 700-1500mm, Length customizable (coil/sheet)
Application Scenarios: Hardware accessories, furniture, shelves, instrument enclosures, ordinary stamping parts, civil products, etc.
Core Features: Adopting ultra-low carbon steel substrate, it has excellent ductility and deep drawing performance, no cracking or wrinkling during stamping, higher surface finish, and can meet the stamping needs of complex shapes.
Specification Range: Thickness 0.2-2.5mm, Width 700-1300mm, supporting coil slitting and flat cutting
Application Scenarios: Home appliances (refrigerator side panels, back panels, inner tanks, air conditioner casings, washing machine inner drums and casings), automotive interior parts, precision stamping parts, decorative panels, etc.
Core Features: Strengthened on the basis of cold rolling, it has high yield strength, excellent tensile strength, certain plasticity, light weight and strong bearing capacity, which can reduce material usage.
Specification Range: Thickness 0.5-4.0mm, Width 700-1500mm, customizable high-strength grade
Application Scenarios: Automotive structural parts, engineering machinery, shelf beams, containers, electrical cabinets, anti-theft doors and windows, etc.
Core Features: The surface of cold rolled steel sheets is treated with galvanizing (GI), galvalume (AZ, such as DC52D+AZ, DC53D+AZ), color coating, etc., which greatly improves corrosion resistance and wear resistance, extends service life, and has aesthetic property.
Key Products: DC51D+GI, DC52D+AZ, DC53D+AZ, Color-Coated Cold Rolled Sheets
Application Scenarios: Outdoor buildings (roofing, wall panels), home appliance casings, automotive parts, photovoltaic brackets, products used in coastal areas, etc.
According to the specific needs of customers, we customize cold rolled steel sheets with special thickness, width, mechanical properties and surface state, and provide one-stop processing services such as slitting, leveling, stamping and bending, adapting to niche and high-precision needs.
Cold rolled carbon steel comes in a variety of carbon content levels:
Low-Carbon Steel
Also known as mild steel, contains less than .3% of carbon. It is highly formable, making it effective for applications that require a great amount of bending and forming.
Medium-Carbon Steel
Contains anywhere from .3% to.6% carbon, which makes it stronger and more durable for applications such as automotive manufacturing.
High-Carbon Steel
Consists of .61% to 1.5% carbon, which changes its physical properties significantly. With higher carbon content, the steel becomes stronger and harder than the lower carbon steels; however, this material exhibits less ductility.
As the core raw material for home appliance manufacturing, cold rolled steel sheets are widely used in refrigerator side panels, back panels, inner tanks, air conditioner casings, heat exchangers, washing machine inner drums and casings, microwave oven and rice cooker casings, etc., due to their high precision and good processability, balancing aesthetics and durability.
Suitable for automotive interior parts (door inner panels, seat components, instrument panel brackets), exterior parts (bumpers, door casings), structural parts (frames, crossbeams). Among them, deep drawing and high-strength cold rolled steel sheets can realize automotive lightweight, reduce energy consumption, and improve body strength.
Used for building ceilings, partition walls, decorative panels, door and window frames, shelves, curtain walls, etc. Surface-treated cold rolled steel sheets (galvalume, color-coated) can be used for outdoor roofing and wall panels, with strong weather resistance, adapting to different architectural styles.
Used for mechanical casings, equipment brackets, hardware accessories, stamping parts, bearing blocks, toolboxes, etc. Ordinary cold rolled steel sheets have controllable costs, and high-strength cold rolled steel sheets can improve the bearing capacity of equipment and extend service life.
Used for electronic equipment casings, instrument casings, precision stamping parts, connectors, etc., requiring high precision and high surface quality, which can meet the strict requirements of precision processing.
