1. Choose the color of the pattern. Marble slabs are colorful, diverse in tones, and have different patterns. This is where the precious charm of marble slabs lies. Basically the same color tone, small color difference, and beautiful patterns are the specific manifestations of good varieties, otherwise it will seriously affect the decorative effect. The nobleness of marble lies in its mottled and colorful patterns. But if you want a better decorative effect, you should choose the same color tone and small color difference. This kind of appearance will look better and more harmonious, but the price is generally not cheap. But speaking of it, sometimes, the price is the same, but the quality is different. This is the issue of cost performance.
2. Check the appearance quality. The appearance of different grades of marble slabs is different. Because marble is naturally formed, defects are inevitable. At the same time, the pros and cons of processing equipment and measuring tools are also the cause of sheet defects. The board body of some boards is not full, the board body is defective, and the board body specifications are different. According to national standards, all grades of marble slabs are allowed to have certain defects, but the superior products are not so obvious. In fact, as long as it is marble, it must have certain defects, mainly depending on whether you will choose a better quality. Marble is naturally formed, defects are inevitable, and when processing, the quality of processing equipment and measuring tools also directly affect the quality of marble.
3. Choose a good grade. According to the allowable deviation of specifications and dimensions, the allowable tolerances of flatness and angle, as well as the appearance quality, surface finish and other indicators. Marble slabs are divided into three grades: high-quality, first-class and qualified products; the classification and identification of marble slabs are mainly identified through the detection of instruments and measuring tools.
