Introduction:Granite square ruler, precision granite square ruler, marble square ruler - All Italian manufacturers produce a large number of granite square ruler products, which are sold all over the country. Among them, they sell well in Guangzhou, Chengdu, Shanghai, Shenyang, Xi'an and other places. Customers who have made purchases can contact us directly.

Granite angle ruler, also known as granite angle ruler, is mainly composed of escaped stones, inclined stones, and a small amount of minerals Olivine, biotite, and trace magnetite, with a black color and precise electrical code structure, have undergone billions of years of aging, resulting in uniform texture, good stability, high strength, and high hardness, and can maintain high precision under heavy loads. Suitable for industrial production Measurement work in production and laboratory.

Advantages of granite square ruler:

1. Rocks undergo long-term natural aging, with complete disappearance of internal stress and no deformation, resulting in high accuracy.

2. 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.

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

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

Granite rectangular ruler is a coarse-grained or medium grained intrusive rock rich in quartz and feldspar, and is the most common deep-seated rock in the crust, formed by the cooling of magma deep in the crust. Used for detection, measurement, marking, equipment installation, and industrial engineering construction. Due to its characteristics of not being easily magnetized, wear-resistant, acid and alkali resistant, invariant, easy to clean, and rust free.

Shortcomings of granite square ruler:

Compared to cast iron square rulers, marble square rulers are relatively brittle and may have pits after being bumped. If there are too many pits, it will affect their accuracy and use. Marble square ruler is mainly used to detect the straightness and perpendicularity of workpieces, and the stone used has a tight structureGood stability, uniform texture, high hardness, and strong strength. The accompanying marble measuring tools include: marble parallel gauge, marble square ruler, marble square tube, etc.
