ZHHIMG® Precision Granite Components: The Foundation of Ultra-Precision

Not all granite is created equal. While many manufacturers use cheaper, lower-density marble or substandard granite, ZHHIMG® exclusively uses our high-density ZHHIMG® Black Granite. With a density of ≈3100 kg/m³, our material surpasses the physical properties of typical black granite from Europe and the Americas.
This superior material, combined with our world-class manufacturing process, results in a product with exceptional characteristics:

●  High Vibration Damping: The high density and unique crystalline structure of our granite effectively absorb and dampen vibrations, ensuring a stable platform for your most sensitive measurements and operations.
●  Low Thermal Expansion: Granite's low coefficient of thermal expansion means your machine base remains dimensionally stable even with temperature fluctuations, a critical feature for high-precision applications.
●  Inherent Stability: Unlike metal, granite does not rust, corrode, or warp over time, providing a reliable, long-term foundation that maintains its accuracy for the life of your machine.
