The coating quality of ppgi prepainted galvanized steel coil is much more uniform, stable, and ideal than that of single piece spraying or brushing on formed metal surfaces. Colored coated steel plates have excellent decoration, formability, corrosion resistance, strong coating adhesion, and can maintain a novel color for a long time. According to the usage experience of international color plates in the past 50 years, when the weather resistance index is 1000h and the acid spray resistance index is greater than 500h, the service life of color coated coil ppgi is about 25 years. Due to the advantages of both steel plates and organic materials, PPGI STEEL COIL have the mechanical strength and easy formability of steel plates, as well as the good decorative and corrosion resistance of organic materials. They can achieve good economic benefits such as replacing wood with steel, efficient construction, energy conservation, and preventing pollution caused by secondary processing. They have…
