Prepainted Galvanised Steel Coil/Sheet JIS DX51D/PPGI Steel Coil For Decoration

Pre-Painted Galvanized Steel (PPGI) & Color Coated Steel Coils Production Process

PPGI steel coils are manufactured by applying a continuous coating of galvanized or aluminum-zinc-silicon alloy onto steel substrates. The production involves:

1. Surface Preparation - Thorough degreasing and chemical pretreatment
2. Coating Application - Precision roll-coating of single or multiple liquid paint layers
3. Curing Process - Controlled baking and cooling for optimal adhesion

Product Characteristics

These color-coated steel products combine:

1. Superior mechanical strength of steel
2. Excellent formability for diverse applications
3. Enhanced corrosion protection through dual-layer defense: Metallic coating (galvanized or Al-Zn-Si),Organic paint layer for additional insulation and rust prevention.

Performance Advantages

1. Long-lasting color retention - Maintains vibrant appearance for years
2. Superior coating adhesion - Withstands harsh environmental conditions
3. Extended service life - Outperforms conventional galvanized steel

Applications

Widely used in:

1. Architectural cladding (exterior walls, roofing)
2. Premium appliance manufacturing
3. Consumer electronics casings
4. Industrial components

Manufacturing Excellence

Produced on high-speed continuous coating lines featuring:

1. - Advanced chemical pretreatment
2. - Precision primer application
3. - Perfect finish coating
4. - This automated process ensures more consistent quality compared to piece-by-piece coating methods.

Color coated steel feature excellent decorativeness, bendability, corrosion resistance, coating adhesion and color fastness.

They are ideal substitutes for wood panels in the construction industry because of their good economic features such as convenient installation, conservation of energy and resistance to contamination.

Color steel sheets with surface texturing on the surface has extremely superb anti-scratch qualities.Can be produced in various colors, and has credible quality and can be mass-produced economically.
