Generally speaking, weathering steel flower boxes have a lifespan of ten years or more. With regular maintenance and avoidance of harsh environments, they should last for over ten or twenty years. The lifespan of weathering steel flower boxes is influenced by many factors, making it difficult to give an exact number. However, we can analyze its durability from the following aspects:

 

  • Material Characteristics: This type of steel has superior corrosion resistance compared to ordinary steel. A dense protective layer forms on its surface, enhancing its weather resistance and allowing it to maintain its performance in atmospheric environments for a long time.
