Introduction
Color coated steel coil, also known as pre-painted galvanized iron (PPGI) or pre-painted galvalume steel (PPGL), is produced by applying an organic coating to the surface of a cold-rolled steel coil, which is then cured at high temperatures. Due to its diverse color options and aesthetic appeal, this type of steel coil finds widespread application in various sectors, including construction, home appliances, and automotive manufacturing. Its primary advantages include excellent corrosion resistance, high oxidation resistance, good mechanical properties, and an attractive appearance.
The manufacturing process of color coated steel coils typically involves several key steps:
1. Material Selection: High-quality cold-rolled steel coils are chosen as the substrate. They undergo cleaning and rust removal processes to ensure a contaminant-free surface for optimal coating adhesion.
2. Primer Application: A primer is applied to enhance the coating's adhesion and corrosion resistance.
3. Curing: After primer application, the steel coil is sent to a drying oven for high-temperature curing, ensuring a strong bond between the primer and the substrate.
4. Top Coat Application: Various colors and patterns can be applied during this step to meet diverse market demands. Like the primer, the top coat also undergoes high-temperature curing for hardness and wear resistance.
