What are the types of granite? Granite stone is expensive? What are the hazards of granite? We all know that granite is a kind of igneous rock formed by the magma under the surface but it is not easy to weather, beautiful colors and other advantages; if everyone is not very understanding of granite, let's take a look at the relevant introduction of granite.
Granite species
Granite has different classifications according to different standards and can be divided into fine-grained granites, medium-grained granites, coarse-grained granites, porphyric granites, porphyritic granites, crystalline granites, and schistose-like granites according to their structural composition. Various types can be divided into: black granite, muscovite granite, hornblende granite, two mica granite.
According to the contained sub-minerals, they can be divided into cassiterite-bearing granites, lanthanum-bearing iron-bearing granites, lanthanum-bearing granites, lepidolites, and tourmaline granites. Commonly petrochemical, gneiss, petrochemical, and other metamorphism. Granite is a widely distributed rock that has been produced in all geologic times. Most of the forms are rock bases, rock strains, and rock bells.
Granite properties
As we all know, granite is beautiful, durable and very hard. This is due to the dense structure of granite, so its high compressive strength, low water absorption, surface hardness, chemical stability, durability, but poor fire resistance.
Granite is fine-grained, coarse-grained, coarse-grained granular structure, or like patchy structure, its particles are fine and uniform, the gap is small (porosity is generally 0.3% ~ 0.7%), water absorption is not high (absorbent rate is generally 0.15 % ~ 0.46%), has good frost resistance.
Granite has a high rate of waste formation and can be processed in various ways. There is also granite that is not weathered and can be used as stone for outdoor decoration. The grain texture of granite is uniform, although the color is mainly pale, but it is also very rich in red, white, yellow, green, black, purple, brown, beige, blue, etc., and its color is relatively small, suitable for large Use of area.
Granite stone price
The granite stone that people see now is created by modern technology. There are many colors and colors. Although there is no real original granite stone, artificial granite stone is also widely used and it is very Loved by people. Different areas of different brands of granite stone prices are different, different specifications of its prices are also different, then the general price of granite stone is between 80 yuan -500 yuan.
The hazard of granite
In recent years, granite has been used in the construction industry and at home. Is granite harmful to the human body? This answer is for sure, because granite will have a slight radiation, according to different materials have different levels of radiation, so people in the purchase and use of granite best to clarify the material and the size of radiation, so as to make home life too More healthy. In addition, granite in some areas will overflow the earthworms, a natural radioactive gas. If you suffer from lung cancer, 13% of lung cancer deaths in Hong Kong are due to excessive gas.
The above information about the types of granite, the price of granite stone , and the hazards of granite are briefly introduced here. We hope to help you. Understand the characteristics of granite, we all in the selection of materials before they can better consider whether to choose granite, and use the size of the area, and so on, multiple elements.

Plate sheet purchase
Hexagon nuts (also known as finished hexagon nuts) are available in ASTM A563-A and are compatible with mild steel Bolts, such as ASTM A307, ASTM F1554 Grade 36, SAE Grade 2 and AASHTO M183. SAE Grade 5 and Grade 8 nuts are also available in finished style. Since hot-dip galvanizing usually increases the thickness of the threaded part of the fastener by 2.2 to 5 mils, the thread size of the galvanized hexagon nut is too large to compensate for the anti-corrosion coating on the bolt.
Chinese hex nut manufacturer Hongchuang Hardware provides hex nuts of various materials, such as carbon steel, stainless steel, alloy steel, titanium, etc.
