Yes, aluminum profiles can be used in cold climates. Aluminum is a lightweight and durable material that maintains its strength and structural integrity even in extreme low temperatures. It does not rust or corrode, which makes it ideal for use in environments with harsh weather conditions. Additionally, aluminum has good thermal conductivity, which allows it to dissipate heat effectively, but it also has low thermal expansion, meaning it does not expand or contract significantly with temperature changes. This characteristic helps prevent warping or cracking in cold climates. Properly designed and installed aluminum profiles can withstand the challenges of cold weather without compromising their performance or longevity.
