No matter how good the product is, it has a certain service life in its application. For ppgi steel products, it is no exception. Many users think that the product life is mainly affected by the quality of the product itself, is this true?
The service life of ppgi steel coil is analyzed on the basis of its coating structure characteristics and mechanism. In essence, it refers to the unified embodiment of effective limit of corrosion resistance of color coating and weather resistance of organic coating under actual application conditions. The concept of service life cannot be consistent if the measurement standard of service limit is not uniform. The service life of ppgi steel coil is evaluated by the long-term exposure test of hanging sheet outdoors under various typical atmospheric environment and corrosive medium working conditions, and the accelerated climate resistance test in laboratory simulation environment.
Therefore, the service life of ppgi steel coil is jointly determined by its own quality and environmental conditions.
