Custom Granite Structural Component

UNPARALLELED LTD is one of the leading manufacturers and suppliers of custom granite structural component in China. With abundant experience, we warmly welcome you to buy advanced custom granite structural component made in China here from our factory. We also accept custom orders.

The UNPARALLELED® Custom Granite Structural Component is designed for high-end metrology and ultra-precision machinery. Manufactured from premium UNPARALLELED® black granite, it provides exceptional dimensional stability, high density (≈3100 kg/m³), and superior vibration-damping performance. This material is far superior to marble or ordinary granite commonly used by low-cost manufacturers, ensuring long-term accuracy and durability even under demanding conditions.

• Ultra-High Precision:

Hand-lapped by master technicians with over 30 years of experience, ensuring micron-level flatness and angular accuracy.

• Excellent Thermal Stability:

Natural black granite has near-zero thermal expansion, maintaining precision in environments with fluctuating temperature and humidity.

• Outstanding Rigidity and Vibration Damping:

The high-density structure minimizes resonance and deformation, providing an ideal foundation for precision motion systems.

• Corrosion and Wear Resistance:

Granite is non-magnetic, rust-free, and resistant to oil and coolants, ensuring long-lasting service life with minimal maintenance.

• Customizable Structure:

Holes, inserts, and threaded bushings can be precisely machined according to customer drawings to integrate sensors, air bearings, or linear stages.

The UNPARALLELED® Custom Granite Structural Component is widely used in:

• Semiconductor equipment (lithography, coating, and inspection systems)
• Coordinate measuring machines (CMM)
• Precision optical and laser equipment
• PCB drilling and inspection systems
• Metrology and calibration instruments
• CNC precision machines and automation platforms

Each granite base is produced in our advanced factory equipped with Taiwan NANTER surface grinders (6000mm capacity) and inspected in a temperature and humidity-controlled metrology lab. Every product undergoes precision testing using Renishaw laser interferometers, WYLER electronic levels, and Mitutoyo digital gauges. All measurements are traceable to the National Metrology Institute standards.

• Keep the granite surface clean and dry after use.
• Avoid direct exposure to high heat or sunlight.
• Use a soft, lint-free cloth with neutral detergent for cleaning.
• Apply a protective cover when not in use to prevent dust accumulation.
• Perform periodic calibration in a controlled environment to ensure long-term precision.
