Granite (huā gāng shí) is a kind of structural rock formed by volcanic erupting lava that rises to the surface of the earth's crust in a molten state under considerable pressure. The magma does not spray out into the air, but gradually cools and solidifies under the ground. It is a kind of deep acidic igneous rock, belonging to magmatic rock. It is igneous rock, also called acid crystalline plutonic rock, which is the most widely dispersed rock in igneous rock. Its composition is mainly silica, accounting for about 65%-75%. The term granite is the meaning of grain. It is often understood as chloroplast in Latin. Granite is the hardest stone because it is composed of small grains. Because of its hardness, corrosion resistance and mirror reflective effect, granite is the hardest stone. Attractive colors, high-quality materials, granite slabs, granite tiles once occupied a significant market share, and granite slabs and ceramic tiles used to be very popular. Because granite is a plutonic rock, it often forms well-developed mineral particles that can be discerned by the naked eye, hence the name. Granite is not easy to weather, the color is beautiful, and the appearance color can last for more than a hundred years. Due to its high hardness and wear resistance, it is not only used for architectural decoration projects and halls, but also for outdoor carving.

The characteristics and advantages of granite also include high load-bearing capacity, compressive ability and good abrasive ductility. Granite is also easy to cut and shape, and it can invent thin slabs. In short, granite has super durability.

Due to its high density, stains are difficult to invade. Polished granite slabs and granite tiles used to be in a very important position in the construction industry all over the world. Granite is also used in exterior wall packaging, roofs, floors and various floor decoration applications. Granite is suitable for door thresholds, cabinet countertops, and outdoor air. Among the cabinet countertops, dark granite is better.
