Understanding Global Cold Rolled Coil: Types and Common Numbers

The model or coil number range of cold-rolled coil is not a fixed and unified concept, because it is affected by many factors, including material, thickness, width, surface treatment method, manufacturer, and specific application requirements. However, I can summarize some common models or specification ranges based on the common cold-rolled coil product characteristics and market applications.

Common Cold-Rolled Coil Specification Range

1. Thickness: The thickness of cold-rolled coil is usually between 0.2mm and 4mm, but the specific thickness can be customized according to customer needs. Common thickness specifications include 0.35mm, 0.4mm, 0.5mm, 0.7mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, etc.

2. Width: The width range of cold-rolled coil is relatively wide, generally between 600mm and 2000mm. Common width specifications include 1000mm, 1250mm, 1500mm, etc. These specifications are more common in the market and can meet most application requirements.

3. Length: The length of cold-rolled coils is usually cut or customized according to customer needs. When delivered in coils, the length may be very long, but in actual applications, it will be cut and processed as needed. Common steel plate length specifications include 1200mm, 1500mm, 2000mm, 2500mm, 3000mm, etc., but not all specifications will appear at the same time, depending on the manufacturer's production capacity and market demand.

Common Cold-Rolled Coil Models

In addition to the above specification range, cold-rolled coils also have a variety of different models or grades, which are usually related to material, performance and application areas. The following are some common cold-rolled coil models:

Q series cold-rolled coils mainly refer to ordinary carbon structural steel cold-rolled coils, and their model range is mainly related to the yield strength of steel. In the Q series, different numbers represent different yield strength grades. The following are some common Q series cold-rolled coil model ranges and their brief descriptions:

Notes

Model differences: Different manufacturers may fine-tune or develop new models of Q series cold-rolled coils according to their own production standards and market needs. Therefore, some non-standard Q series models may be encountered in practical applications.
Application fields: Q series cold-rolled coils are widely used in many fields such as automobile manufacturing, electrical products, locomotives and rolling stock, aviation, precision instruments, food canning, etc. The specific type of cold-rolled coil to be used needs to be selected according to the use environment and performance requirements of the product.

Summary

The model range of Q series cold-rolled coils mainly includes Q195, Q215, Q235, etc. These models represent different yield strength grades. When selecting, it is necessary to weigh them according to specific use needs and performance requirements. At the same time, it is also necessary to pay attention to the differences between different manufacturers and standards to ensure that the selected products meet actual needs.

SPCC series cold-rolled coils are the steel names of "general cold-rolled carbon steel sheets and strips" under the Japanese standard (JIS). Many countries or companies directly use them to indicate similar steels produced by themselves (such as the Baosteel Q/BQB402 standard has SPCC). SPCC series cold-rolled coils usually have different surface quality, processing performance, and use grades. The following is a summary of the model range of SPCC series cold-rolled coils:

Notes

Model differences: Different manufacturers may fine-tune or develop new models of SPCC series cold-rolled coils according to their own production standards and market demand. Therefore, some non-standard SPCC series models may be encountered in actual applications.

Performance differences: Even the same model of SPCC series cold-rolled coils may have different performances due to differences in production processes, chemical composition, and surface treatment. Therefore, it is necessary to weigh the specific use needs and performance requirements when selecting.

Application areas: SPCC series cold-rolled coils are widely used in many fields such as automobile manufacturing, home appliance manufacturing, and metal product processing. The specific model of the cold-rolled coil to be used needs to be selected according to the product's use environment and performance requirements.

Summary

The model range of SPCC series cold-rolled coils includes the basic model SPCC, the extended models SPCD and SPCE, and possible special-purpose models. When selecting, it is necessary to weigh the specific use needs and performance requirements and consider the differences between different manufacturers and standards.

DC series cold-rolled coils are a type of cold-rolled steel sheet, which is widely used in many fields such as automobiles, home appliances, and metal products. Its model range is mainly divided according to the mechanical properties and uses of the materials. The following is a summary of the DC series cold-rolled coil model range:

Notes

Model differences: Different manufacturers may fine-tune or develop new models of DC series cold-rolled coils according to their own production standards and market demand. Therefore, some non-standard DC series models may be encountered in actual applications.

Performance differences: Even the same model of DC series cold-rolled coils may have different performances due to differences in production process, chemical composition, and surface treatment. Therefore, it is necessary to weigh the specific use needs and performance requirements when choosing.

Application field: DC series cold-rolled coils are widely used in many fields such as automobile manufacturing, home appliance manufacturing, and metal product processing. The specific model of the cold-rolled coil to be used needs to be selected according to the product's use environment and performance requirements.

Summary

The model range of DC series cold-rolled coils includes basic models DC01, DC02, DC03, DC04, etc., as well as possible extended models and special-purpose models. When choosing, it is necessary to weigh the specific use needs and performance requirements and consider the differences between different manufacturers and standards.

The model range of ST series cold-rolled coils mainly includes ST12, ST13, ST14, ST15, ST16, etc. These models are commonly used grades for cold rolling of steel, each with different mechanical properties and uses.

In summary, the model range of ST series cold-rolled coils mainly includes ST12, ST13, ST14, ST15, ST16, etc., but the specific models may vary from steel mill to steel mill and product to product. When selecting materials, it is recommended to refer to the product manual provided by the steel mill or consult professionals for accurate information.

It should be noted that these models are only part of the cold-rolled coils. There are many other models and specifications of cold-rolled coil products on the market. In addition, different manufacturers may develop unique models and specifications based on their own production capacity and market demand.

Conclusion

In summary, the model or coil number range of cold-rolled coils is a relatively flexible and broad concept. When selecting cold-rolled coils, the appropriate model and specification should be determined according to the specific application needs and performance requirements. At the same time, it is also necessary to pay attention to the differences between different manufacturers and standards to ensure that the selected products meet actual needs.
