PPGI Coil (Pre-painted Galvanized Steel Coil), relying on the dual protection of the galvanized layer and the surface coating, possesses excellent corrosion resistance, weather resistance, and decorative properties, making it suitable for various indoor and outdoor applications. However, its corrosion resistance is slightly inferior to PPGL, especially in extreme corrosive environments such as high salt spray. The following are its main application environments:

Outdoor Construction Environments: It can withstand regular outdoor weather conditions such as sunlight, rain, wind, and snow in most regions. It is a commonly used material for industrial plants, warehouses, prefabricated houses, and light steel structure residences, suitable for making roofs, exterior wall panels, rolling doors, and rainwater pipes. For example, it can be used for the enclosure structures of small shops and community facilities in cities, as well as agricultural warehouses and prefabricated houses in rural areas, offering both practicality and aesthetics with low maintenance costs. However, it should be noted that PPGL is more recommended for highly corrosive coastal areas with high salt spray, and PPGI is only suitable for secondary building components in coastal areas.

Low-Temperature Insulation and Sealing Environments: It is suitable for special low-temperature and sealed environments such as cold storage and clean workshops. PPGI is often used to make sandwich insulation panels for these places. Its coating and galvanized layer can resist moisture corrosion in low-temperature environments, and when combined with insulation materials such as polyurethane, it helps maintain a constant temperature in the space. For example, it is commonly used in the walls and roofs of food cold storage facilities and the enclosure structures of clean production workshops in the pharmaceutical industry
