Anti-Fingerprint PPGI Coil
Permanent Fingerprint Resistance for High-Traffic Surfaces | ASTM A755 / EN 10346 Compliant
Anti-Fingerprint PPGI Coil, also known as AFP Prepainted Galvanized Steel Coil or Anti-Fingerprint Galvanized Color Coil, is a high-quality pre-coated steel product designed with a transparent organic anti-fingerprint coating to prevent oxidation, rust, and fingerprint marks.
This advanced coating improves surface corrosion resistance, aesthetic appearance, and cleanability, making it ideal for home appliances, electronics, roofing, and architectural panels.
Manufactured in compliance with ASTM A755 / JIS G3312 / EN 10169, our Anti-Fingerprint PPGI Coils are available in regular spangle, zero spangle, and matte surface finishes with custom RAL color options.

Our PPGI coils feature a nano-ceramic modified polyester/polyurethane coating applied over galvanized steel (GI base). The micro-ridged surface structure (Ra 0.8–1.5μm) combined with oil-repellent additives creates a permanent anti-fingerprint effect without compromising corrosion protection.
Engineered with nano-ceramic coating, this PPGI coil permanently resists fingerprints and smudges.
Withstands 5,000+ rubs (ISO 11998) while maintaining color integrity (ΔE<1.0).
Ideal for elevator interiors, commercial kitchens, and high-touch surfaces.
Reduces cleaning costs by 72% versus standard coated steels.

Coating Structure (Typical)
Top Side (Exterior Layer):
AFP Clear Coating → Finish Paint → Primer → Zinc Layer → Cold-Rolled Steel Substrate
Back Side (Interior Layer):
Epoxy or Single-Layer Back Paint → Zinc Layer → Base Steel
🧪 AFP coating acts as a nano-protective barrier against corrosion, moisture, and fingerprints.
