Metal sculptures in urban or industrial environments face constant exposure to pollution, which can lead to corrosion and deterioration. To ensure longevity, artists employ several strategies. First, they choose corrosion-resistant metals like stainless steel, bronze, or corten steel, which naturally develop a protective patina.

Another common method is applying protective coatings, such as clear lacquers, powder coatings, or wax layers, to shield the metal from moisture and airborne pollutants. Regular maintenance, including cleaning and reapplying coatings, is also crucial.

Some artists use galvanization or anodizing processes to enhance durability. Additionally, strategic placement—avoiding high-pollution zones or using protective enclosures—can minimize exposure. By combining these techniques, artists ensure their metal sculptures remain vibrant and intact despite harsh environmental conditions.
