Granite slabs are widely used in precision industries due to their exceptional stability, hardness, and resistance to deformation. As the foundation for measurement and calibration in laboratories, workshops, and manufacturing facilities, granite slabs must maintain their accuracy over years of continuous use. However, even the finest granite can lose its precision if handled or maintained incorrectly. Understanding the proper precautions when using granite slabs is essential for ensuring long-term reliability and accuracy.
The first key consideration is proper handling. Although granite is extremely hard, it is also brittle and can be damaged by impact. When moving or installing granite slabs, specialized lifting equipment such as cranes or soft straps should be used. Never drag or push the slab across rough surfaces, as this may cause chipping or micro-cracks on the edges and corners. During use, operators should avoid placing metal tools, heavy objects, or sharp instruments directly on the surface to prevent scratches or dents that can compromise measurement results.
Environmental stability is another critical factor. Granite slabs should be placed in a clean, temperature-controlled environment with low humidity and minimal vibration. Extreme temperature fluctuations can cause thermal expansion and contraction, leading to minor yet measurable deviations in flatness. Vibration from nearby machinery can also affect accuracy, so isolation from active equipment is recommended. Ideally, granite slabs should rest on properly designed support stands or bases that distribute weight evenly and prevent distortion.
Cleaning and maintenance play a vital role in extending the service life of granite slabs. The surface should be kept free of dust, oil, and debris, as even microscopic particles can influence measurement precision. Cleaning should be performed with soft, lint-free cloths and neutral cleaning agents. Avoid using alcohol, solvents, or abrasive materials that could alter the surface texture. After cleaning, the surface should be dried completely to prevent moisture absorption. Regular calibration is also necessary to ensure the slab maintains its certified accuracy level.
At ZHHIMG®, we emphasize that precision begins with care. Our granite slabs are made from ZHHIMG® Black Granite, known for its superior density, stability, and thermal resistance compared to standard European and American granites. When used and maintained properly, these slabs can preserve micron or even sub-micron flatness over decades. Many of our clients in industries such as semiconductor manufacturing, optics, and metrology rely on ZHHIMG® granite slabs as the foundation of their precision systems.
By following correct handling, installation, and maintenance procedures, users can ensure that their granite slabs deliver consistent accuracy and performance throughout their operational life. A well-maintained granite slab is more than a measuring tool—it is a long-term investment in precision, reliability, and quality assurance.
