Granite square / Marble square


Granite squares, also known as marble squares, are precision marble measuring tools made of natural stone materials such as "Jinan Qing", "Taishan Green", and "Taishan Green White Grain".

The main mineral components of granite square are escalator, oblique stone, small amount of olivine, biotite and trace magnetite, black color, precise structure, after hundreds of millions of years of aging, uniform texture, good stability, high strength, High hardness, can maintain high precision under heavy load. Suitable for industrial production and laboratory measurement work.

Because it is not easy to magnetize, wear resistance, acid and alkali resistance, invariant, easy to clean, not rust, etc., granite square is easier to maintain relatively high verticality and straightness, this is a cast iron square incomparable.

However, granite squares are also inadequate: compared to cast iron squares, granite squares are more brittle and have pits after being bumped. If there are more pits, their accuracy and use will be affected.

Granite squares are mainly used to detect the straightness and verticality of the workpiece. The stone materials used are characterized by compact structure, good stability, uniform texture, high hardness, and high strength.
