As an industrial product, it also has its own standard service life, which determines the length of our actual use of webbing. Generally, there are two kinds of situations at the end of use. One is the problem of quality or external damage within the service life, so it can no longer be used. The other is the problem of natural wear and fracture, which is natural damage. It is also inevitable. Today we will talk about the life span in detail. How long is the life span?
