Check the appearance quality of marble:
The appearance of marble sheets of different grades is different. Because marble is naturally formed, defects are inevitable. At the same time, the advantages and disadvantages of marble processing equipment and measuring tools are also the reasons for sheet defects. Some boards are not full (warped or dented), have defects (cracks, blisters, stains, etc.), and have different board specifications (such as missing edges and corners, irregular board), etc. According to the national marble standard, all grades of marble sheets are allowed to have certain defects, but the superior products are not so obvious.
