Aluminum strips are generally suitable for cold climates. Aluminum has a low coefficient of thermal expansion, which means it doesn't expand or contract significantly with temperature changes. This property makes it resistant to the effects of cold weather. Additionally, aluminum is lightweight, durable, and corrosion-resistant, which are desirable traits in materials used in cold environments. However, it's important to consider specific applications and the quality of the aluminum strip, as certain alloys or treatments may affect performance in extreme cold.
