Metal sculptures are a striking addition to urban landscapes, but their longevity in high-pollution environments is often questioned. Pollution, particularly from industrial emissions and vehicle exhaust, accelerates corrosion and discoloration of metals like bronze, steel, and iron. However, modern sculptors employ advanced techniques to combat these effects.

Stainless steel and corten steel are popular choices due to their inherent corrosion resistance. Protective coatings, such as wax, lacquer, or powder coatings, further shield sculptures from acidic rain and airborne pollutants. Regular maintenance, including cleaning and reapplying protective layers, is crucial for preserving their appearance.

Despite challenges, metal sculptures can endure for decades with proper care. Their ability to withstand urban pollution makes them a durable and visually impactful form of public art, enriching cities worldwide.
