The lifespan of aluminum strips can vary significantly based on factors such as the environment in which they are used, the quality of the material, and the specific application. In general, if properly maintained and not exposed to harsh conditions, aluminum strips can last for several decades. For instance, in construction, aluminum strips used in framing can have a lifespan of 20 to 40 years. However, in more aggressive environments or with frequent wear and tear, this lifespan can be considerably shorter. It's important to note that aluminum is a recyclable material, and its lifespan can be extended through recycling processes.
