The granite surface plate is made of high-quality "Jinan qing" stone material through mechanical processing and manual precision grinding.

Black luster, precise structure, uniform texture, good stability, high strength, high hardness, can maintain high accuracy under heavy loads and general temperatures, and has advantages such as rust resistance, acid and alkali resistance, wear resistance, non magnetization, and unchanging shape. Granite surface plate are suitable for measuring tools in mechanical factories.

Granite surface plate is a precision benchmark measurement tool made of natural stone materials.

It is an ideal reference plane for the inspection of instruments, precision tools, and mechanical components. Especially for high-precision measurement, due to its unique characteristics, cast iron flat plates are dwarfed.
