Metal urban outdoor furniture is a popular choice for its durability and modern aesthetic. However, a common concern is how its temperature holds up under direct sunlight. The short answer is yes, metal furniture can get extremely hot to the touch, posing a burn risk and reducing comfort.
The science is straightforward: metals are excellent conductors of heat. When exposed to direct sunlight, the metal surface absorbs radiant energy efficiently, causing its temperature to soar significantly above the ambient air temperature. On a sunny 90°F (32°C) day, dark-colored metal surfaces like wrought iron or steel can easily reach 130-150°F (54-66°C) or higher—temperatures that can cause pain or even first-degree burns upon contact within seconds.
Several factors influence how hot the furniture gets:
* Material Type: Aluminum generally heats up less than cast iron or steel.
* Color: Dark colors (black, charcoal) absorb more heat than light colors (white, beige).
* Ambient Temperature & Sun Intensity: Higher air temperatures and intense, direct sun lead to hotter surfaces.
* Design: Thin, solid sheets heat faster than ornate, airy designs with more surface area to dissipate heat.
To mitigate this issue, consider these solutions:
1. Use Protective Cushions: Adding thick cushions creates a barrier between users and the hot metal.
2. Choose Lighter Colors: Opt for powder-coated finishes in light shades to reflect more sunlight.
3. Prioritize Shade: Placing furniture under umbrellas, pergolas, or trees is the most effective way to keep it cool.
4. Explore Alternative Materials: For full-sun locations, consider furniture made from wood, high-density polyethylene (HDPE) plastic, or vinyl-coated mesh, which stay cooler.
In conclusion, while metal outdoor furniture is sturdy, its heat retention in direct sun is a significant drawback for comfort and safety. By understanding the factors at play and implementing strategic solutions like shade and accessories, you can enjoy the benefits of metal furniture without the burn.
