Coil coating is a continuous process that applies custom coatings on steel/aluminum coil before fabrication into final products. In a continuous and/or automated process, the coating material is applied to the rolled metal strip. Coil coating employs efficient principles such as continuous coating, pre-painting, pre-priming, pretreating, and cleaning of sheets of aluminum, steel, or flat metal coils. Aluminum or steel rolls are coated with a topcoat, a back coat, and primers (which come in a variety of colors and finishes).
Aluminum or steel coil is continually coated at a predefined point before manufacturing in the coil coating process. The coil is first uncoiled and then painted or re-coated to meet specific needs. Coatings can be applied in a variety of ways, including electroplating, electrostatic coating, and galvanization. Coil-coated goods are utilized in a wide range of sectors, including construction and architecture, where pre-painted metal is used for facades, roofs, gutters, ceilings, and several auxiliary components.
As a result of the fast expansion of the building and architectural industries, the need for coil coated items is expanding, boosting the demand for coil coating globally. According to the India Brand Equity Foundation (IBEF), India, China, and the United States are predicted to contribute to about 60% of global building growth by 2025. The coil is unwound, pre-treated, and cleaned before being applied to a flat continuous sheet, heat-cured, cooled, and rewound for shipment.
Coil coating is applied to rolled metal strips in a continuous process that involves cleaning and chemical pre-treatment of the metal surface (if necessary). The coil coating technology has been around for a while and helps businesses to create durable and appealing goods. Because the metal is coated before too, rather than after, manufacturing, coil coating is also known as pre-painted metal.
