High Strength PPGI Steel Coils with Zinc Coating Range from 30 to 275 Grams per Square Meter and Multiple Organic Coating Layers

Product Introduction

ChromaSteel™ PPGI is a premium composite material that combines the strength of steel with the 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.

Technical Specifications & Parameters

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.

Color & Aesthetics

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.

Coating Layers Explained

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.

Primary Applications

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.

Key Advantages of ChromaSteel™

• 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 $le 3T$).

• 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.
