Pre-Painted Galvanized Iron (PPGL)
Color Coating Steel Sheet
This product uses cold-rolled or galvanized steel sheets as the base material. After surface pretreatment (degreasing, cleaning, chemical conversion), coatings are applied via continuous roller coating, followed by baking and cooling. Known as "color coated steel" due to its diverse color options, it combines durability with aesthetic versatility for industrial and architectural applications.

Available Coating Solutions
Our pre-painted galvanized steel coils (PPGI) offer a range of high-performance coatings tailored to your specific environmental and performance needs.
1.Polyester (PE)
– Balanced cost efficiency with strong flexibility and color retention
– Ideal for indoor applications or moderate climates
2. High Durability Polyester (HDP)
Advanced polymers boost UV,chalk resistance and 15-year color stability for exteriors/roofs.
3.Silicone-Modified Polyester (SMP)
– Enhanced UV resistance and color stability vs. standard PE
– Recommended for outdoor architectural components
4.Polyvinylidene Fluoride (PVDF)
– Superior chemical resistance and 20+ year weatherability
– First choice for harsh environments or premium façades
Key Features & Benefits
1. Exceptional Corrosion Resistance
- The zinc coating and passivation film provide outstanding bare metal corrosion resistance.
- In dry environments, zinc remains stable. In humid conditions, a dense layer of zinc carbonate forms, shielding the underlying steel from further oxidation.
2. Eco-Friendly & Safe
- Zero harmful elements: Both the zinc layer and passivation film are free from environmentally hazardous substances, complying with global sustainability standards.
3. Customizable Zinc Coating
- Coating weight ranges from 80–200 g/m*, tailored to meet specific project requirements.
- Adjustable zinc spangle patterns (e.g., minimized, regular, or zero-spangle) for aesthetic or functional needs.
4. High-Quality Base Material
- Manufactured from cold-rolled steel of varying strengths and thicknesses, ensuring structural integrity and adaptability.
- Uniform dual-sided coating enhances durability for long-term outdoor or harsh environment use.
5. Broad Applications
- Ideal for construction (roofing, cladding), automotive components, household appliances, and industrial equipment.Features
