Key Advantages

Extreme Wear Resistance

With HS70+ Shore hardness, our granite rulers outperform steel and aluminum, resisting scratches and dents over decades of heavy use.

Superior Thermal Stability

Low thermal expansion ensures minimal dimensional change during temperature shifts, critical for foundries and cold storage.

Non-Magnetic Purity

Ideal for CNC machines and sensitive sensors, preventing magnetic interference found in traditional metal rulers.

Corrosion Proof

Non-porous crystalline structure repels oils, coolants, and moisture, ensuring no rust or degradation in machining shops.

Vibration Damping

Dense granite structure absorbs mechanical vibrations from nearby presses, ensuring steady and accurate readings.

Customizable Solutions

Available in bespoke sizing with custom engraving for scales and company logos to fit unique industrial workflows.

Frequently Asked Questions

Q: Why is granite preferred over steel for industrial level rulers?

Granite offers superior thermal stability, higher hardness (HS70+), and is naturally non-magnetic and corrosion-resistant, making it far more durable and accurate in workshop environments.

Q: What is the difference between 0 and 00 grade precision?

Grade 00 provides tighter tolerances (up to 0.0005mm/m straightness) compared to Grade 0, making it ideal for ultra-precision aerospace and semiconductor inspections.

Q: Can these rulers be used near high-power magnetic fixtures?

Yes, granite is non-magnetic, meaning it will not be attracted to or interfere with magnetic fixtures or CNC machinery, ensuring safe and accurate measurements.

Q: How do you prevent the spirit level vials from leaking or evaporating?

Our vials are precision-embedded and hermetically sealed to prevent fluid evaporation, maintaining bubble alignment accuracy within 0.02mm/m.

Q: What is the typical lead time for custom size granite rulers?

Depending on the complexity of the customization and order volume, we can leverage our 1200 piece/day capacity to provide rapid turnaround times.

Q: How should I maintain the surface of a granite straight ruler?

Simply wipe the surface with a clean, soft cloth to remove oil or dust. Its non-porous nature prevents contamination from penetrating the material.
