1. Significant thermal expansion and contraction: High temperatures in summer can cause expansion and deformation, while low temperatures in winter may lead to cracking due to contraction. Sufficient expansion joints should be reserved during installation. Areas with large temperature differences are particularly pronounced, resulting in increased maintenance costs in the later stages

2. Weak load-bearing capacity: Snow or heavy objects can easily cause dents and deformations, so caution should be exercised when using in snowy areas in the north. The bearing capacity is only 60% of traditional ceramic tiles, which is not suitable for building structures that require load-bearing.

3. Insufficient weather resistance: Surface powdering is prone to occur after 5 years, and salt spray corrosion is more severe in coastal areas. Poor quality products age and crack within 3 years.
