Granite slabs are precision reference tools made from natural stone materials. They serve as an ideal benchmark for the inspection of instruments, precision tools, and mechanical components, especially in high-precision measurement applications. These slabs are known for their exceptional stability, accuracy, and durability.
Granite slabs can be damaged if struck by heavy objects, but they are far superior to cast iron or steel reference plates in terms of accuracy and long-term stability. A 1000×630mm "00" grade granite slab produced by our company was tested and retained its original precision after one year of storage, proving its reliability.
Made from high-quality rock layers that have undergone millions of years of natural aging, granite slabs offer extreme dimensional stability. This means you don’t have to worry about deformation due to temperature changes. The material is carefully selected and undergoes strict physical testing to ensure fine crystallization and hardness. Since granite is a non-metallic material, it doesn't react magnetically and doesn't experience plastic deformation.
Granite slabs are highly resistant to wear, corrosion, and chemical damage. They remain stable under heavy loads and normal temperatures. Their long-term natural aging results in a uniform structure, a minimal linear expansion coefficient, and the complete elimination of internal stress, ensuring no deformation over time. As a result, granite slabs maintain high precision, excellent rigidity, and strong wear resistance.
