does aluminum railing get hot

Aluminum’s high thermal conductivity means railings exposed to direct sunlight can heat up quickly, reaching surface temperatures significantly above ambient air temperature. In hot climates or direct sun—common on rooftop terraces and balcony edges—an uncoated aluminum handrail can feel uncomfortably warm to the touch. Archsky addresses this by offering powder-coat finishes with near-infrared (NIR) reflective pigments that reduce heat absorption, as well as anodized surfaces that dissipate heat more evenly. Strategic design choices—such as incorporating wooden or composite top rails, ventilated handrail profiles, or shade sails—further mitigate surface temperature gain. By combining coating technology and smart design, Archsky’s aluminum railing solutions maintain user comfort even under intense sunlight.
