Cold Rolled Steel Coil
Cold Rolled Steel Coil undergoes a process of being rolled at room temperature, which enhances its strength, surface finish, and dimensional accuracy. This process results in a smooth, polished surface that is both aesthetically pleasing and ideal for precision applications.
Cold Rolled Steel Coil is essential in the manufacturing sector for producing automotive components, machinery parts, and electrical appliances. In construction, it is used for structural elements and decorative finishes. Its versatility also extends to furniture, fixtures, and hardware, highlighting its broad application range due to its superior strength, formability, and high-quality surface finish.
Cold rolled steel coil full hard (CRFH) refers to a type of steel coil that has undergone a cold rolling process and has been rolled to its full hard state. This means that the steel has been rolled to its maximum level of hardness and strength. It is typically used in applications where high strength and durability are required, such as in automotive manufacturing, construction, home appliances, industrial equipment, electrical industry. It’s also commonly used as substrate for GI, GL, PPGI and PPGL, etc.
| Product | Cold Rolled Steel Coil | CRFH |
| Thickness | 0.25 – 2.00 MM | 0.10 – 2.00 MM |
| Width | 600 – 1250 MM | 600 – 1250 MM |
| Steel Grade | SPCC-SB, SPCC-SD, DC01, ST12, or others | SPCC-1B, or others |
| Some Key Features | |
| Smooth Surface Finish | Cold rolled steel coil has a smooth and uniform surface finish due to the cold rolling process. This results in a more precise and consistent thickness across the coil, making it ideal for applications where a smooth surface is required. |
| Tight Tolerances | Cold rolled steel coil is known for its tight dimensional tolerances and uniform thickness. The cold rolling process allows for greater control over the thickness and flatness of the steel, resulting in a high-quality product with consistent properties. |
| Strength and Durability | Cold rolled steel coil is known for its high strength and durability. The cold rolling process work-hardens the steel, making it stronger and more resistant to bending and deformation compared to Hot rolled steel. |
| Some Common Applications | |
| Automotive Industry | Cold rolled steel is used in the automotive industry to manufacture various components such as body panels, chassis parts, engine parts, and structural components. Its high strength, precise dimensions, and smooth surface finish make it ideal for automotive applications. |
| Construction | Cold rolled steel is used in the construction industry for structural components, roofing, framing, and other building materials. Its strength, durability, and dimensional accuracy make it a popular choice for construction projects. |
| Appliances | Cold rolled steel is commonly used in the manufacturing of household appliances such as refrigerators, washing machines, dryers, and ovens. Its smooth surface finish and formability make it suitable for appliance panels and casings. |
| Furniture | Cold rolled steel is used in the furniture industry to manufacture metal furniture, shelving units, cabinets, and other furniture components. Its strength, versatility, and aesthetic appeal make it a popular choice for furniture design. |
| Metal Fabrication | Cold rolled steel is widely used in metal fabrication processes to create a wide range of products such as brackets, enclosures, containers, and structural components. Its workability and formability make it suitable for various fabrication techniques. |
| Piping and Tubing | Cold rolled steel is used in the manufacturing of pipes, tubes, and other hollow structural sections for various applications such as plumbing, construction, and industrial systems. Its uniform thickness and smooth surface finish ensure consistent performance in piping systems. |
| Electrical Enclosures | Cold rolled steel is used in the production of electrical enclosures, cabinets, and panels due to its strength, durability, and corrosion resistance. It provides protection for electrical components in various industrial and commercial applications. |
Product Advantages
1.The cold-rolled coil products are accurate in size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.
2.It is possible to obtain extremely thin strips that cannot be produced by hot rolling (up to 0.001 mm or less).
3.The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide, etc.,which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be produced according to user requirements. Rough surface, etc., to facilitate the processing of the next process.
4.The cold rolled plate has a good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawability, etc.).
5.High-speed rolling and full-continuous rolling can be realized with high productivity.
