Metal sculptures in urban environments face significant challenges from industrial pollution, which can cause corrosion and discoloration. To combat this, artists employ a variety of strategies to ensure their creations remain durable and visually striking.

One key method is selecting corrosion-resistant metals like stainless steel, bronze, or corten steel, which naturally develop a protective patina. Additionally, artists apply specialized protective coatings such as clear lacquers, epoxy resins, or powder coatings to shield the metal from harmful pollutants.

Regular maintenance, including cleaning and reapplying protective layers, is also crucial. Some artists even incorporate design elements that minimize pollution exposure, such as elevated placements or sheltered installations.

By combining material science with artistic ingenuity, urban metal sculptures can withstand industrial pollution while maintaining their beauty for generations.
