If you have a sunny rooftop with no shade, you are right to be concerned about the metal parts of your urban outdoor furniture getting hot. The short answer is yes, metal furniture can become too hot to touch when exposed to direct, intense sunlight for prolonged periods. Metals are excellent conductors of heat. When sunlight hits a metal surface, the material absorbs the solar energy efficiently and its temperature can rise significantly above the ambient air temperature. On a hot, sunny day, dark-colored or black metal surfaces can easily reach temperatures high enough to cause discomfort or even minor burns.
However, this doesn't mean you must avoid metal furniture altogether. Several factors influence how hot it gets. Lighter-colored metals or powder-coated finishes in beige, white, or light gray absorb less heat than dark bronze or black. The specific type of metal also matters, with aluminum generally heating up less than wrought iron or steel. The most effective strategy is to manage the exposure. Using large umbrellas, retractable awnings, or shade sails can dramatically reduce direct sun contact. For existing furniture, consider adding thick outdoor cushions, which provide insulation and protect you from direct contact with hot surfaces. Simple practices like draping a light-colored sheet over chairs when not in use can also prevent excessive heat buildup. With thoughtful selection and smart shading, you can enjoy stylish metal furniture on your sun-drenched rooftop without the burn.
