Are cast iron outdoor sculptures suitable for use in geothermal active regions?

Cast iron outdoor sculptures are known for their durability and classic aesthetic, but their suitability in geothermal active regions depends on several factors. Geothermal areas often feature high temperatures, acidic soils, and corrosive gases, which can accelerate rust and degradation in cast iron. While cast iron is robust, its susceptibility to corrosion may require frequent maintenance, such as protective coatings or sealants, in such environments. Additionally, rapid temperature fluctuations in geothermal zones can cause thermal stress, potentially leading to cracks or structural weaknesses over time. For long-term use, alternative materials like bronze or stainless steel might offer better resistance. However, with proper treatment and care, cast iron sculptures can still be a viable option, blending artistry with resilience in challenging landscapes.
