The appearance of different grades of stone home improvement boards is different!

The appearance of different grades of stone home improvement panels is different. Because marble is naturally formed, disadvantages are inevitable. At the same time, the quality of processing equipment measuring tools is also the reason for the shortcomings of the plate.

According to national standards, all grades of marble slabs are agreed to have certain shortcomings, but the superior products are so obvious. Marble processing manufacturers take you to learn more!

The unevenness of the surface gloss of the stone home improvement board will greatly affect the decoration effect.
