Yes, the metal parts of urban outdoor furniture can absolutely get too hot to touch on a sunny rooftop with no shade. Metals are excellent conductors of heat. When placed in direct, uninterrupted sunlight, they absorb a significant amount of solar radiation, causing their temperature to rise rapidly and often far above the surrounding air temperature. On a hot summer day, dark-colored or low-emissivity metal surfaces like aluminum or steel can easily reach temperatures exceeding 60°C (140°F), which is high enough to cause painful burns or blisters on contact.
This presents a clear safety hazard and makes the furniture unusable during the peak hours of sunlight. To mitigate this issue, consider these solutions. First, look for furniture with powder-coated finishes in lighter colors, as they tend to absorb less heat than dark, bare metal. Second, incorporate shade solutions such as a large umbrella, a retractable awning, or a shade sail to protect the furniture. Third, use thick, fitted cushions and fabric covers that can act as a protective barrier between you and the hot metal. Finally, when selecting new furniture, explore alternative materials like all-weather wicker, teak, or certain heat-resistant polymers that do not absorb and retain heat as intensely as metal. By taking these proactive steps, you can create a safer and more enjoyable rooftop oasis.
