Prepainted Galvanized Steel Coil or Color Coated Steel Coil is a manufactured product resulting from the treatment of cold-rolled steel plate and galvanized steel plate through a series of surface preparation steps such as degreasing, cleaning, and chemical conversion. The process involves continuous coating through roll application, followed by baking and cooling. The resulting coated steel sheet is characterized by its lightweight nature, attractive appearance, excellent corrosion resistance, and the ability to undergo direct processing. This product serves as a novel raw material in various industries including construction, shipbuilding, vehicle manufacturing, household electrical appliances, and the electrical industry. It has proven effective in replacing wood with steel, facilitating efficient construction, promoting energy conservation, and preventing pollution.

Structure:
- Topcoat (finishing): Provides color, enhances visual appeal, and forms a protective barrier film for long-term durability.
- Primer coat: Prevents paint undercutting and reinforces corrosion resistance.
- Pretreatment layer: Applied to ensure strong adhesion and further enhance corrosion resistance.
- Base steel sheet: The foundational material for the entire product.
