Prepainted galvanized steel coil, also known as PPGI, is one of the most widely used materials for manufacturing corrugated roofing sheets and metal roof tiles. Produced with high-quality galvanized or galvalume steel as the base, it is coated with polyester (PE), SMP, HDP, or PVDF paints that ensure long-lasting color retention and excellent corrosion resistance.

The smooth, decorative, and durable surface finish makes it ideal for residential, commercial, and industrial roofing systems. The color-coated layer provides enhanced protection against UV rays, moisture, and temperature variations, making the material suitable for outdoor exposure in all climates.

Standard thickness ranges from 0.12mm to 1.2mm, with widths between 600mm and 1250mm. Zinc coating levels (Z40–Z275) ensure high performance in both humid and coastal environments. The coil can be easily formed into corrugated roofing profiles, wall claddings, or sandwich panels, making it a versatile option for construction and architectural applications.

Each PPGI coil undergoes strict quality control testing, including coating adhesion, hardness, salt-spray, and bending tests, to meet ASTM, JIS, and EN standards. The products are packed with waterproof film and steel straps to prevent moisture damage during shipping.
