  Coil coating is the way in which the coating material is applied to a strip of steel or aluminum. A coil of sheet metal is fed continuously into the process, which is controlled by accumulators at each end of the line. They load the bare metal coils at one end and release the finished product at the other end. In between, a coil coating process is used. What we are doing actually means high speed, continuous coil coating. What makes high speed, continuous coil coating possible is the uninterrupted application of cleaning, handling, coating, curing and potential leveling, while the sheet is flat, all in one high speed path through the coil  coating line.   Advantages Coil coating is replacing traditional manufacturing methods with value-added processes. The old practice of painting unpainted cars is being replaced by penetrating metal sheets. They are used for Nip coating or Dip coating with minimal solvent usage, helping to reduce VOC's. Coil coating is applied to flat ...

  Pre-painted metals are produced by continuously adding paint or film coatings to strip metals, primarily steel and aluminum. This process is called coil coating. The process involves cleaning and chemical pretreatment of the metal surface and one or both sides as necessary, single or multiple applications of (liquid) paint or coating powder, followed by curing or lamination with plastic film. The coated surface can have a wide range of colors, gloss levels and surface textures. It is the end use of the finished product that determines the coating choice. The user may require non-stick properties, high flexibility or high chemical resistance. Modern developments offer many new coating types to meet the growing needs of users.  Manufacturer LITONG  gives you an overview of developments in metal coating technology and paint technology. Painting metal industry There are several options for applying paint to metal. In the field, it is common to spray or brush; in the factory...
