ppgi coil
PPGI coil, or Pre-Painted Galvanized Iron coil, represents a revolutionary advancement in construction and manufacturing materials. This versatile product consists of a steel substrate that undergoes hot-dip galvanization and is then treated with a sophisticated paint coating system. The manufacturing process involves multiple layers, including a zinc coating for corrosion resistance, a primer for enhanced adhesion, and a top coat that provides both aesthetic appeal and additional protection. The coil's structure typically features a zinc coating weight of 60-275g/m2 and a paint coating thickness ranging from 15-25 microns, depending on specific applications. PPGI coils are manufactured in various widths, typically from 600mm to 1250mm, making them suitable for diverse industrial applications. The material's core strength lies in its combination of structural integrity and surface protection, offering superior resistance to weathering, chemical exposure, and mechanical stress. These coils are engineered to maintain their appearance and protective properties throughout their service life, typically spanning 10-15 years under normal conditions. The product's versatility extends to its finish options, including regular spangle, zero spangle, and various surface treatments, allowing for customization based on specific project requirements.
