Application description
Widely used for roofing and wall cladding (corrugated panels, tiles, sandwich panels), household appliances (refrigerator doors, washing machine panels), automotive parts, lighting fixtures, furniture, and electrical enclosures. The color coating provides aesthetic appeal and long-term weather resistance, making it ideal for outdoor, architectural, and decorative applications.
Production description
Galvanized or galvalume coil is cleaned, pretreated, and coated with primer and topcoat (polyester, PVDF, HDP, or SMP) via reverse roll coating. Each layer is cured in ovens. The strip is then cooled, inspected for color and coating adhesion, trimmed, and rewound. Backside coating optional.
Shipping Packaging
For export, pre-painted coils are wrapped with VCI paper and moisture-proof polyethylene, placed on ISPM-15 certified wooden pallets or steel skids, secured with steel straps, and fitted with edge protectors and coil protectors. Labels include color code, grade, coating type, dimensions, and coil weight for safe sea freight.

FAQ
1. How to maintain color consistency over time?
PVDF and HDP coatings offer the best UV resistance (fading warranty up to 10–15 years). PE is suitable for indoor or less demanding outdoor use. Regular cleaning extends color life.
2. Can pre-painted coils be roll-formed without damaging the coating?
Yes. Use proper tooling with smooth, clean rolls. Avoid sharp bends below the minimum recommended radius (typically 3x sheet thickness). Lubrication may help.
3. How to store coated coils before fabrication?
Store indoors, dry, with original wrapping intact. Avoid direct sunlight, high humidity, and stacking heavy coils on top to prevent pressure marks on the coating.
