铝合金实木结构的车库门，由于木材的特性受气候湿度等环境影响，开裂是不可避免。虽然可以通过烘干、油漆等工艺减小开裂，但不能做到完全避免。  而铜质车库门，采用外包铜皮和内充聚氨酯的结构，这两种材料都非常稳定，不会出现变形的情况，因此维护保养非常方便。有的用铜皮取代门板聚氨酯发泡门板两面的彩钢板，外观古朴高贵，适用于高档别墅的车库门。
Because of the influence of climate and humidity on the properties of wood, cracking of the garage door with aluminium alloy solid wood structure is inevitable. Although the cracking can be reduced by drying and painting processes, it can not be avoided completely. Copper garage doors are made of copper coat and polyurethane, which are very stable and will not be deformed, so maintenance is very convenient. Some use copper instead of polyurethane foam door panels on both sides of the color steel plate, simple and noble appearance, suitable for high-end villas garage doors.
聚氨酯是导热系数极低的材料，广泛用于冰箱等需要隔热的场合，铜质车库门由于填充了5cm厚聚氨酯，保温性能要较实木车库门更好。
Polyurethane is a material with very low thermal conductivity. It is widely used in refrigerators and other occasions requiring insulation. Copper garage door has better thermal insulation performance than solid wood garage door because it is filled with 5 cm thick polyurethane.
铜器一直是中国传统文化中尊贵的象征，铜质车库门的黄铜采用做旧处理后具有高贵而又古朴的风格，配合表面的装饰，又不显得单调，非常适合高档别墅。
Bronze wares have always been the symbol of honor in Chinese traditional culture. The brass of copper garage doors is noble and primitive style after old treatment. It is suitable for high-grade villas because it matches the surface decoration without being monotonous.
现在市场上大多的别墅车库门都采用实木结构，因此选用铜质车库门的方案显得很新颖而不平凡。
At present, most of the villa garage doors on the market are made of solid wood, so the scheme of copper garage doors seems novel and extraordinary.
