High Hardness, Abrasion Resistance Granite

Granite magma is deep in the ground by condensation and the formation of deep into acidic igneous rocks, magmatic and sedimentary rocks of granite formed by metamorphism or migmatization gneiss rock.

Because granite is plutonic rocks, often can form mineral particles are well developed, recognizable, hence the name. Granite not easily weathered, beautiful color, appearance color can be maintained for more than a century, due to its high hardness, abrasion resistance, besides being used for advanced architectural decoration engineering, the ground outside the hall, or open first choice for carving wood, can also be used in the laboratory of this special environment.

Application value:

The physical characteristics of granite be richly endowed by nature with its beautiful patterns makes him become the building of good material, known as the "king of rock" said. In the construction of granite from the roof to the can use floor, many need to expose to wind and rain resistance or need for places or objects are made of granite. Like Taipei "in the memorial hall" brand and the Tiananmen in Beijing before the monument to the people's heroes are made of granite. Characteristics of granite after a thousand years are still enduring, the famous Egyptian pyramids has proved this point.
