ArcelorMittal Dofasco "Pre-Coat" prepainted steel is produced from substrates of Cold Rolled, Galvanized, GalvalumeTM or Tin Mill Products, that are painted in coil form with protective, decorative coatings. The coatings are inorganic and organic-based and are baked-on at our continuous coil coating complex.
ArcelorMittal Dofasco Pre-Coat steel simplifies production by eliminating customer in-plant post-painting. This can produce savings, such as expenditures on post-painting facilities. Further economies can be achieved in space, labour, inspection, fire insurance premiums, energy and pollution control.
The precision of the prepainting process and the many tests conducted before, during, and after production contribute to the consistent quality of ArcelorMittal Dofasco Pre-Coat.
Customers can choose from any of the proven colours* and paint systems available or can request new colour development.
