PPGI & PPAL Sheets – Engineered for Longevity and Aesthetics in Modern Construction
In the fast-paced world of construction and home appliances, choosing the right material means choosing long-term profitability. Our PPGI (Pre-Painted Galvanized Iron) and PPAL (Pre-Painted Aluminum-Zinc Alloy Coated Steel) combine the strength of steel with the protective power of advanced coatings. They offer vivid colors, superior corrosion resistance, and excellent formability, making them the ideal solution for roofing, siding, structural purlins, and electrical appliances.
Key Advantages
1. Superior Corrosion Resistance
PPGI: Based on hot-dip galvanized substrate. The zinc layer provides excellent cathodic protection, effectively preventing rust even at cut edges.
PPAL: Based on 55% Al-Zn coating. The aluminum layer forms a dense insulating barrier. It offers 2 to 4 times better anti-rust performance than standard galvanized sheets, making it the perfect choice for coastal areas, chemical plants, and high-humidity environments.
2. Rich Colors & Finishes
We support RAL, PANTONE, or customized colors. Available coating types include PE (Polyester) , SMP (Silicone Modified Polyester) , HDP (High Durability Polyester) , and PVDF (Polyvinylidene Fluoride) . Matte, glossy, or embossed textures are available to suit any architectural style.
3. Excellent Workability
Engineered for high adhesion and flexibility, our coatings won't peel, crack, or flake during severe deformation. Whether you need bending, stamping, deep drawing, or roll forming, the color layer remains intact. Perfect for corrugated sheets, C/Z purlins, and door panels.
4. Eco-Friendly & Sustainable
Our production process meets international environmental standards (RoHS, REACH). As a green building material, the coated steel is 100% recyclable, helping your projects achieve LEED certification.
Applications
Building & Construction: Steel structure workshops, clean rooms, roof tiles, wall cladding, prefab houses, noise barriers.
Home Appliances: Refrigerator side panels, washing machine housings, microwave ovens, air conditioner shells.
