Metal sculptures face significant challenges when exposed to extreme temperature fluctuations, which can cause cracking, warping, or corrosion over time. Artists employ several strategies to enhance durability. First, material selection is crucial—stainless steel, bronze, and weathering steel are popular choices due to their low thermal expansion rates and natural resistance to temperature shifts.

Structural design also plays a key role. Artists incorporate expansion joints or flexible connections to accommodate metal's natural movement during temperature changes. Proper welding techniques prevent weak points that could fail under stress. Many sculptors apply specialized protective coatings like powder coatings or patinas that act as thermal barriers while enhancing aesthetic appeal.

For outdoor installations, artists often elevate sculptures slightly to prevent ground temperature extremes from affecting the base. Regular maintenance, including inspections for stress fractures and recoating when necessary, further ensures longevity. By combining these methods, artists create metal artworks capable of enduring decades of environmental challenges while maintaining their visual impact.
