How does aluminum’s resistance to microbiologically influenced corrosion benefit outdoor tree boxes?

Aluminum’s resistance to microbiologically influenced corrosion (MIC) makes it an excellent material for outdoor tree boxes, particularly in urban environments. MIC occurs when microorganisms, such as bacteria or fungi, accelerate the degradation of materials. Unlike wood or untreated steel, aluminum naturally forms a protective oxide layer that prevents microbial attack, ensuring long-term durability.

This corrosion resistance reduces maintenance costs and extends the lifespan of tree boxes, even in humid or wet conditions. Additionally, aluminum is lightweight yet sturdy, making it easy to install and relocate. Its eco-friendly properties, including recyclability, further enhance its appeal for sustainable urban landscaping.

By choosing aluminum tree boxes, cities and landscapers can ensure reliable protection for trees while minimizing environmental impact and upkeep efforts.
