FAQ
Q: What is the difference between granite and marble surface plates?
A: Granite is significantly denser, harder, and more stable than marble. It is resistant to rust, acid, and alkali, and does not deform over time. Marble is softer, prone to wear, and can absorb moisture, leading to dimensional instability. UNPARALLELED® granite plates offer superior performance and longevity.
Q: How do I maintain my granite surface plate?
A: Maintenance is minimal. Simply wipe the surface with a clean, soft cloth after use. Avoid abrasive cleaners or harsh chemicals. Store in a clean, dry environment. Periodic recalibration is recommended to ensure continued accuracy.
Q: Can you customize the size and features of the surface plate?
A: Yes, we specialize in custom solutions. We can manufacture plates to your exact dimensions and add features such as T-slots, tapped holes, dowel pins, and specialized surface finishes.
Q: What is the lead time for custom orders?
A: Lead times vary depending on the complexity and size of the order. Please contact us with your requirements for a specific quote and timeline.
Q: Do you offer international shipping?
A: Yes, we ship globally. Our strategic location near the Port of Qingdao ensures efficient logistics to destinations worldwide.
