Color Coated Steel Coil (PPGI and PPGL)
Color coated steel coil, known as PPGI and PPGL prepainted coil, adopts hot-dip galvanized or galvalume base metal with organic polymer paint coating. , it integrates anti-corrosion performance, decorative color and easy forming. We supply multi-paint, multi-color coated coils, support custom color, coating thickness and slitting service for construction, home appliance and architectural decoration industries.
Available Grades
- PPGI Prepainted Galvanized Coil: Zinc-coated base color steel coil, cost mainstream grade, great inland anti-rust performance, the most popular material for ordinary factory roofing and wall cladding.
- PPGL Prepainted Galvalume Coil: Al-Zn alloy substrate coated coil, 2-3 times longer service life than PPGI, excellent salt corrosion resistance for coastal and high-humidity outdoor projects.
- PE Polyester Coated Coil: Standard economy paint grade, good color adhesion, easy bending processing, ideal for general indoor decoration and low-budget building projects.
- HDP High Durability Polyester Coil: Weather-resistant upgraded paint, strong UV anti-fading ability, fit long-term outdoor exposed building exterior usage.
- PVDF Fluorocarbon Coated Coil: Premium anti-aging grade, ultra anti-fading, acid and alkali resistant, customized for high-end facade and corrosive industrial plant exterior.
Product Features
- Dual-layer Anti-corrosion Protection: Combined metal substrate + organic paint double protection, effectively isolate air, moisture and chemical medium to avoid steel rusting.
- Rich Custom Color Matching: Support RAL standard color, customized matte/glossy finish, uniform surface color, no color difference for batch finished products.
- Excellent Cold Forming Performance: Flexible integrated coating, no peeling or cracking during bending, stamping and profiling, adapt secondary profiling processing.
- Strong Weather & UV Resistance: High-grade paint resists sunlight aging, rain erosion and temperature alternation, keep original color for 15-30 years outdoors.
- Lightweight & High Structural Strength: Low unit weight reduces building load, stable base steel mechanical strength, easy transportation and on-site installation.
- Fire-retardant & Easy Maintenance: Standard fireproof coating grade optional, smooth surface dust-proof, easy daily cleaning without extra anti-rust maintenance.
