Overview of PPGI/PPGL Coil
PPGI or PPGL (color-coated steel coil or prepainted steel coil) is a product made by applying one or several layers of organic coating on the surface of steel plate after chemical pretreatment such as degreasing and phosphating, and then baking and curing. Generally, hot-dip galvanized sheet or hot-dip aluminum Zinc plate and electro-galvanized plate are used as substrates.

Advantage and Application
The hot-dip Al-Zn substrate adopts hot-dip Al-Zn steel sheet (55% Al-Zn) as the newly coated substrate, and the content of Al-Zn is usually 150g/㎡ (double-sided). The corrosion resistance of hot-dip galvanized sheet is 2-5 times that of hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490°C will not severely oxidize or produce scale. The ability to reflect heat and light is 2 times that of hot-dip galvanized steel, and the reflectivity is greater than 0.75, which is an ideal building material for energy saving. The electro-galvanized substrate uses electro-galvanized sheet as the substrate, and the product obtained by coating organic paint and baking is electro-galvanized color-coated sheet. Because the zinc layer of the electro-galvanized sheet is thin, the zinc content is usually 20/20g/m2, so this product Not suitable for use in making walls, roofs, etc. outdoors. But because of its beautiful appearance and excellent processing performance, it can be mainly used in home appliances, audio, steel furniture, interior decoration, etc. about 1.5 times.
