The lifespan of outdoor mesh banners can vary depending on various factors such as the quality of the material, the weather conditions they are exposed to, and how well they are maintained. Generally, outdoor mesh banners can last anywhere from 1 to 5 years. With proper care and regular maintenance, such as cleaning and storing them properly when not in use, they can last longer. However, it is important to note that UV rays, strong winds, and harsh weather conditions can deteriorate the material over time, so it is recommended to periodically inspect and replace them if necessary.﻿
