Finishing constitutes the final stage of cold-rolled coil production, primarily comprising the following operations: trimming, which removes irregular edges to ensure width precision; re-coiling, where large coils are cut into smaller coils according to customer specifications; straightening, which corrects wave and bend deformations in the steel plate using a straightening machine; surface inspection, where surface defects are detected manually or via online systems to reject non-conforming products; oiling, applying rust-preventive oil as required; packaging, following standard procedures to safeguard product quality during storage and transport; labelling, marking packaging with product information (grade, specification, weight, production date, etc.). Finishing processes directly impact final product quality and user experience, necessitating strict control of process parameters and operational standards at every stage.
