Authentic Steel manufactures and exports high-quality Regular Polyester (PE) PPGI Steel Coils (prepainted galvanized steel coils), engineered to combine vibrant aesthetic versatility with reliable, cost-effective weather resistance. Produced via a continuous multi-stage coil coating process, prime cold-rolled steel substrates are hot-dip galvanized, surface-treated with chemical conversion layers, primed, and baked with premium polyester organic topcoats.
Regular Polyester (PE) color-coated steel coils are the most widely used prepainted metal solution globally for commercial, industrial, and residential construction. Combining excellent paint adhesion, flexible formability, and reliable resistance to moisture, oxidation, and chalking, PE PPGI coils offer an economical, long-lasting solution for modern architectural building envelopes.
