Generally speaking, the same kind of granite can be divided into several grades according to the grade of the stone rough material. For example, barry gray granite is divided into different grades such as A, B, and C according to the source of the rough material. The quality and price of the same type of granite vary greatly between different grades. Therefore, the classification of stone is very important in the purchase of stone. The most effective way to distinguish different grades of stone is comparison. It is difficult to see the quality of the same grade of stone alone, but it is easy to distinguish the quality of different grades of stone together. So when you decide to buy a certain kind of granite, check whether the stone has been graded, and buy the grade with fresher material, brighter color, and denser structure.
Let's take the barry grey granite flamed board as an example. Barry Grey Granite slab is a very common facing stone material. In the industry, we divide them into three categories: A, B, and C according to whether the finished surface has color difference, black spots, stone lines, and flaws.
Among them, A material is the best, C material is the worst, and there are more detailed classifications such as ABCDE in some places, and the worse the letters are.
The biggest difference between sesame gray stone, whether it is A material or C material, is the color and texture.
A Material: The sesame gray flamed board of A material has no color difference, no black spots, no stone lines, and looks very neat and tidy overall. This type of flamed board is relatively expensive and is usually used for dry hanging of indoor and outdoor walls.
B Material: The surface of the sesame gray flamed board of B material has no obvious color difference, no large black spots, and no overly obvious white and blue stone lines. This type of flamed board is also of good quality. Generally, some projects with higher quality requirements will choose Class B flamed boards for laying the ground.
C Material: The surface of the sesame gray board of C material may have color difference, and may also have defects such as black spots and stone lines. However, even Class C can guarantee that there are no cracks and no damage on the surface. In terms of use quality, it is the same as Class A, but it does not look as good as Class AB. This type of board is often used in some parks, sidewalks and other projects with huge consumption.
