The acid-resistant curtain wall tiles typically refer to thicker plates used for building facades. The wear-resistant flamed finish curtain wall tiles can be made from materials such as stone, concrete, or metal.

The flamed surface is a surface treatment technology that involves exposing the stone surface to high-temperature flames, resulting in a natural and rough texture.
