In cold climates, aluminum sheets should be selected with consideration for their thermal expansion properties. It's important to use alloys with low thermal expansion coefficients to minimize distortion. Additionally, the design should account for potential contraction and expansion to prevent warping or cracking. Proper insulation and sealing are crucial to prevent condensation and moisture buildup, which can lead to corrosion. It's also advisable to use thicker sheets to enhance durability and resistance to the elements. Regular inspections and maintenance are recommended to ensure the longevity of aluminum structures in cold environments.
