Black Galaxy Granite which the building materials market is called granite, but the definition of geology and petrology belongs to gabbro, and the golden sand is bronze pyroxene. Bronze pyroxene is known for its special metallic luster compared to other minerals of the pyroxene family. Divided into a large star, small star. black galaxy of the origin is India.
There are large, medium and small galaxy, there are thick and thin points, the stone commonly used in our door stone is black galaxy granite countertop, thickness <1.5cm, about 1.2-1.4cm, black granite is very particular about integrity, that is the door stone is best to be a piece of stone. Our doors are generally around 90cm.

The particles are uniform and fine, the gap is small (the porosity is generally 0.3% to 0.7%), and the water absorption rate is not high (the water absorption rate is generally 0.15%). 0.46%), has good antifreeze properties. The hardness of granite is high, its Mohs hardness is about 6, and its density is between 2.63g/cm3 and 2.75g/cm3. Its compressive strength is 100-300MPa, and fine-grained granite can be as high as 300MPa or more. At 10 to 30 MPa.
Bulk density 2.97g/cm, water absorption rate 0.19%, compressive strength 122.6Mpa, flexural strength 17.4Mpa, Mohs hardness 6.6, gloss 86.6
