How do expansion joints in wrought iron animal sculptures accommodate thermal changes in desert climates?

Wrought iron animal sculptures in desert climates face extreme temperature fluctuations, which can cause metal to expand and contract significantly. To prevent cracking or warping, expansion joints are strategically incorporated into the design. These joints act as flexible buffers, allowing the metal to move naturally without stress buildup. Typically, expansion gaps are placed at key stress points, such as joints or curves, and may include overlapping or sliding mechanisms. This engineering ensures the sculpture remains intact and visually appealing despite the harsh desert environment. Properly designed expansion joints also reduce maintenance needs, preserving the artwork's longevity. By accommodating thermal changes, these features showcase the harmony between artistry and functionality in metalwork.
