The coil coating line is designed in a way that ensures the coil passes through all its functional zones at the same speed.
The coating process begins with a multi-stage chemical rinse that removes impurities from the coil. A chrome-free passivation layer is applied to the clean surface to ensure good adhesion of the coating. After it has dried, the coating is applied to the coil by coating rollers, and then the coil is cured in ovens at a temperature of up to 254°C. The coil is cooled and dried, after which it is sent for packaging or further machine processing.
In addition to the application of organic coatings, the line is also used to apply laminating films.
Both coated and laminated sheets have high resistance to climatic, mechanical and chemical influences. We test all of this in laboratories as well as in real conditions.
