Color-coated galvanized steel coil is a composite material made of galvanized steel coil (hot-dip galvanized or electro-galvanized) as the base material, which is coated with high-performance coating (polyester, fluorocarbon, silicon modification, etc.) after surface chemical treatment (such as passivation, phosphating), and then cured by high-temperature baking. It combines the anti-rust performance of the galvanized layer and the decorative properties of the color coating.
color coated galvanized coil/PPGI Coil Advantages
✅ Super weather resistance: PVDF fluorocarbon or high weather-resistant polyester coating is used, which is UV-resistant and has long-lasting color without fading (10-20 years color retention).
✅ Excellent anti-corrosion: Galvanized substrate + organic coating double protection, salt spray test can reach more than 1000 hours without rust.
✅ Beautiful and diverse: Provide a variety of colors (RAL color card optional) and surface textures (glossy/matte/embossed) to meet personalized needs.
✅ Lightweight and high-strength: Lighter than traditional building materials (such as tiles), but with high strength, suitable for large-span structures.
✅ Environmental protection and energy saving: Recyclable, some coatings have heat reflection function, reducing building energy consumption.
