The lifespan of an outdoor metal sculpture depends on several critical factors, from material selection to environmental exposure. High-quality metals like stainless steel, bronze, or corten steel naturally resist corrosion, making them ideal for outdoor installations. Weather conditions, such as rain, humidity, and extreme temperatures, significantly impact durability, requiring protective coatings like powder coating or wax to prevent rust. Regular maintenance, including cleaning and inspections, helps identify early signs of wear. Proper placement—away from direct saltwater spray or industrial pollutants—also extends longevity. By combining durable materials, protective treatments, and consistent care, artists and collectors can ensure their metal sculptures withstand the test of time.
