How does aluminum compare to stainless steel in terms of durability for outdoor flower boxes?

When choosing materials for outdoor flower boxes, durability is a key factor. Aluminum and stainless steel are both popular options, but they differ significantly in performance. Aluminum is lightweight, corrosion-resistant, and doesn’t rust, making it ideal for wet climates. However, it can dent more easily than stainless steel. Stainless steel, on the other hand, is heavier and highly resistant to impacts and scratches, but it may develop surface rust if not properly maintained. For long-term outdoor use, stainless steel often outperforms aluminum in harsh conditions, though aluminum is more affordable and easier to handle. Consider your climate and maintenance preferences when selecting the best material for your garden.
