Granite Square

The characteristics of granite square ruler: Granite square ruler is made of stone material through mechanical processing and manual precision grinding. Black luster, precise structure, uniform texture, good stability, high strength, high hardness, able to maintain high precision under heavy load and general temperature, and has the advantages of non rusting, acid and alkali resistance, abrasion resistance, non magnetization, and invariance.

The mechanical properties of granite rulers: Granite rulers are not easily deformed, rust prone, easy to use, and widely used for inspection and measurement.

Granite rock rulers are made of materials such as fine-grained gray cast iron or alloy cast iron, with a working face and side hardness of 170-220HB. The working face should be ground using grinding technology. Granite rock ruler is suitable for equipment installation, commissioning, construction, decoration and other industries.

Granite square ruler is used for verticality and parallelism detection, and can be used as a 90 ° measurement benchmark.

Granite square ruler standard: manufactured according to the mechanical industry standard JB/T10027-99.

Granite ruler accuracy: Granite rulers are divided into three levels: level 1, level 0, and level 00

Granite square ruler packaging: generally packaged in wooden boxes.

Granite stone ruler color: black
