Yes, aluminum profiles can be used in cold climates. Aluminum is a durable material with excellent resistance to corrosion and weathering, including low temperatures. It maintains its strength and does not rust or degrade in cold conditions. However, it's important to consider thermal expansion and contraction, as aluminum expands and contracts more than some other materials. Proper design and installation practices can mitigate these effects, making aluminum profiles suitable for use even in extreme cold environments.
