A high-quality granite surface plate is the foundation of accurate measurement. ZHHIMG’s surface plates are hand-finished by masters with over 30 years of experience, achieving nanometer-level flatness. Trusted by national metrology institutes, our tools comply with DIN876, ASME, and JIS standards, ensuring absolute reliability for your quality control.
H2: Nanometer-Level Flatness and Precision
Our granite surface plates serve as the absolute benchmark for inspection. Thanks to our “Walking Electronic Level” masters—craftsmen with over 30 years of hand-grinding experience—we can achieve nanometer-level flatness. This extreme precision is essential for calibrating high-end equipment and ensuring the accuracy of granite measuring rulers and squares.

H2: Comprehensive Range of Granite Measuring Tools
Beyond surface plates, we offer a full suite of measurement tools, including granite square rulers, straight rulers, V-blocks, and parallels. Our rulers, often used for equipment assembly and calibration, can achieve a precision of 1μm. These tools are indispensable for maintaining quality in aerospace, automotive, and precision machining sectors.
