Why is cast iron outdoor seating unsuitable for high-moisture tropical climates?

Cast iron outdoor seating, while durable and stylish, is poorly suited for high-moisture tropical climates due to its susceptibility to rust and corrosion. In humid environments, moisture accelerates oxidation, causing unsightly rust and structural weakening over time. Regular maintenance, such as sealing and painting, becomes a tedious necessity to prevent deterioration. Additionally, cast iron retains heat, making it uncomfortable to use in already warm tropical settings. For these reasons, materials like aluminum, teak, or synthetic wicker are often better choices for outdoor furniture in such climates, offering greater resistance to moisture and lower maintenance requirements.
