Overview of PPGI
PPGI, also known as pre-coated steel, coil coated steel, and colour coated steel, stands for Pre-Painted Galvanised Iron. Galvanized Iron is obtained when coated steel is continuously hot dipped to form Zinc of purity greater than 99%. The galvanized coating provides cathodic and barrier protection to the base steel. PPGI is made by painting of Galvanized Iron prior to formation as it significantly reduces corrosion rate of zinc. Such a corrosion protection system makes PPGI attractive for structures designed to last a long time in aggressive atmospheres.

Applications of PPGI Coil
Pre-painted galvanized steel coil can be further processed into plain, profile, and corrugated sheets, which can be used in many areas, for example:
1. Construction industry, such as roofing, interior, and exterior wall panel, the surface sheet of the balcony, ceiling, partitioning walls, windows, and door panels, etc. The PPGI steel is durable and wear-resistant and it will not be deformed easily. So it is also widely used in the renovation of buildings.
2. Transportation, for example, decorative panels of the car, deck of train or ship, containers, etc.
3. Electrical equipment, mainly used to make shells of the freezer, washing machine, air conditioner, etc. The PPGI coils for home appliances are of the best quality, and the production requirements are the highest.
4. Furniture, like wardrobe, locker, radiator, lampshade, table, bed, bookcase, shelf, etc.
5. Other industries, such as roller shutters, advertising boards, traffic signboards, elevators, whiteboards, etc.
