1. Low cultural identity: Aluminum tiles themselves have a clear metallic luster and lack a rustic matte texture, which easily appears "modern" and "not dignified".

2. High noise: When aluminum tiles encounter severe weather conditions such as storms and hail, they will make noisy noises, which may have an impact on living and residential environments.

3. Dead insects: The surface of aluminum tiles is smooth and prone to accumulating dust and organic matter, attracting insects; Cracks and depressions are prone to hiding insects; High temperature environment accelerates insect death and decay; Lack of regular cleaning and maintenance leads to the accumulation of dead insects.

4. Fragile: The surface of aluminum tiles is relatively weak and easily damaged or deformed by external forces. Especially in severe weather such as rainstorm, wind and hail, it is easy to be damaged, thus affecting its performance and service life.

5. Easy to seep water: The surface of aluminum tiles is relatively smooth, and the friction force is small when water flows through, which can easily cause problems such as poor water flow and water leakage. Especially in the rainstorm season or the area with complex terrain, the leakage problem will be more significant.
