Pickled carbon steel coils undergo an acid - cleaning process to eliminate the scale and oxide layer generated during hot - rolling, resulting in a clean surface ready for further processing. These coils are predominantly utilized in applications that require subsequent surface treatments, like electroplating, painting, or powder coating. In the automotive and appliance industries, pickled carbon steel coils are used to make components that need protective coatings to enhance corrosion resistance and appearance, such as car body parts and appliance exteriors. The furniture industry also employs these coils for manufacturing decorative and structural elements that demand a high - quality surface finish. Moreover, pickled carbon steel coils find use in the production of metal artworks, decorative items, and general - purpose metal products where a pristine surface is crucial for aesthetic and functional purposes.
