Pre-painted steel coil, also referred to as Color Steel Coil, is based on hot-dipped Galvanized Steel Sheet. Talk over with factory pre painted zinc coated metallic, in which the metallic is painted before forming, in preference to publish portray which happens after forming.Its major characteristics include top colorability, formability and corrosion resistance, as well as the mechanical electricity and processability of steel plate.Clients can recommend necessities to producers in keeping with their own specs of prepainted steel coil, as a way to perform manufacturing.
The color coating production process is divided into substrate pretreatment, chemical conversion film (non-organic metal coating), organic non-metal coating, and some production lines have post-coating processes. Organic coatings are divided into primers and topcoats. The requirements for primers are not high and can be painted smoothly. However, for the sake of production safety, companies generally use color reverse coating methods for primers and topcoats. Post-coating process: The post-coating process includes printing, embossing, peelable protective film, lamination, etc., which increase the decoration and protection performance of the color coated steel sheet.
