Roller-coated products represent the most mature process in this industry. Roller-coated products are colored when raw materials are rolled into rolls, and then undergo sheet metal forming processing and post-production processes in the factory. Roller-coated products have uniform and consistent colors, and are less likely to have color differences compared to spray-coated products. Currently, roller-coated products are generally materials with a thickness of 1.5mm or less. If the arc of the plate is too large, it is suitable for decorative metal plates Composite processes need to be carried out to ensure the flatness of its products.
The raw materials for roller-coated products are in full rolls, and the products to be ordered have a certain minimum order quantity. In addition, roller-coated products are thin plates and are not suitable for some complex shapes. The film thickness of roller-coated products is 25μm, while that of spray-coated products is 65 to 80μm. In terms of thickness, roller-coated products are not as good as spray-coated products.
