Introduction:Granite and other tall blocks, marble and other tall blocks, Shanghai granite and other tall blocks - Quanyi Machinery Manufacturers produce a large number of granite and other tall blocks in January, and we have stock of universal specifications. If you need them, you can contact us directly.

Granite blocks, also known as marble blocks, are used to measure the parallelism of parts. Generally supplied in groups, the quantity of each group can be produced and processed according to the customer's design requirements.

Introduction to high block products such as granite:

Material: High qualityJinan Qing "natural marble and granite.

Processing: Materials are mechanically processed and hand crafted by professional technicians.

Advantages: Black luster, precise structure, uniform texture, good stability, high strength, high hardness, no rust, acid or alkali resistance, no magnetization, no deformation, good wear resistance.

Advantages of granite and other tall blocks:

1. After long-term natural aging, the rock has a uniform organizational structure, a very small coefficient of expansion, and the internal stress completely disappears without deformation, resulting in high accuracy.

2. Good rigidity, high hardness, and strong wear resistance.

3. Not afraid of acid and alkali erosion, will not rust, does not need to be oiled, is not easy to stick to dust, easy to maintain, and has a long service life.

4. No scratches, not hindered by constant temperature conditions, and able to maintain temperature measurement accuracy at room temperature.

5. Non magnetized, able to move smoothly during measurement, without any sluggishness, not affected by moisture, and the plane is properly weighed.

Physical properties of granite and other high blocks:

1. Specific gravity: 2970-3070kg/m3

2. Pressure resistance strength: 2500-2600kg/cm3

3. Elastic coefficient: 1.27-1.47 × 106N/mm2

4. Water absorption rate: 0.13%. Shore hardness: above HS70.
