ChromaSteel™ PPGI is a premium composite material that combines the strength of steel with superior corrosion resistance of zinc and the aesthetic versatility of high-grade organic coatings. Unlike traditional post-painting methods, PPGI is produced through a Continuous Coil Coating Process.

The process involves cleaning, pre-treating, and applying multiple layers of organic coatings (primer and finish paint) in a highly controlled factory environment. The result is a vibrant, uniform finish that offers significantly higher durability and weather resistance than spray-painted steel. ChromaSteel™ is the preferred choice for modern architecture and high-end appliance manufacturing where both form and function are non-negotiable.

Our PPGI is built upon a high-quality Hot-Dip Galvanized (GI) base to ensure that even if the paint layer is scratched, the underlying steel remains protected.

ChromaSteel™ offers an unlimited palette for creative expression:

• Color Selection: Full range of RAL and Pantone colors
• Special Finishes: Wood grain, marble texture, brick patterns, and camouflage
• Protective Film: Optional PE/PVC transparent film can be applied to protect the surface during fabrication and installation

1. Top Finish (Clear/Color): Provides the final color, UV resistance, and scratch protection
2. Primer: Enhances adhesion between the paint and the metal
3. Pre-treatment: A chemical conversion layer for enhanced corrosion resistance
4. Zinc Layer: The cathodic protection layer (from the GI substrate)
5. Base Steel: The core providing structural integrity

1. Architectural Exteriors: Premium roofing tiles, sandwich panels, curtain walls, and rolling shutter doors
2. Interior Decoration: Ceiling boards, fireproof doors, and wall partitions
3. Home Appliances: Decorative side panels for high-end refrigerators, microwave ovens, and DVD player housings
4. Transportation: Container panels, vehicle interiors, and highway signboards

• UV & Weather Resistance: Our PVDF-coated series offers up to 20 years of color retention without significant fading or chalking
• Superior Flexibility: The coating is designed to remain intact during bending, drawing, and roll-forming (T-bend ≤ 3T)
• Environmental Sustainability: Factory-applied coatings minimize VOC emissions compared to site-painting
• Cost Efficiency: Eliminates the need for a separate painting process in your production line, reducing labor and time
