Why Granite Is Trusted For Metrology

Granite provides a stable, non-magnetic, corrosion-resistant surface, perfect for demanding metrology environments.

Its natural hardness, rigidity and fine-grained structure provide an extremely stable reference surface for high-accuracy measurement. Granite offers excellent flatness retention, low thermal expansion and minimal susceptibility to warping or deformation over time, even in controlled or fluctuating environments.

Inherent vibration damping helps reduce measurement error, while resistance to corrosion and wear makes granite well suited to both laboratory and industrial use. Unlike metallic alternatives, granite is non-magnetic and chemically inert, ensuring consistent measurement performance across a wide range of conditions.

When correctly specified, installed and maintained, granite delivers consistent, repeatable performance.

  • Natural vibration damping capacity
  • High stiffness - elastic modulus
  • Excellent corrosion and chemical resistance
  • Low water absorption
  • Non-magnetic and electrically insulating
  • Chemically inert
  • Low maintenance requirements
  • Long service life
  • Cost-effective for precision inspection and metrology applications
Granite bed plates

Granite Bed Plates

Granite bed plates provide a rigid and stable foundation for inspection and measurement applications.

Designed for floor-mounted applications, typically surface-mounted.

Bed plates can be fully customised in size, layout, and interface features to meet specific inspection and operational requirements.

Surfaces available plain, with T-slots or threaded interface features.

Granite Surface Tables

Granite surface tables provide a rigid and stable foundation for inspection and measurement applications.

They serve the same fundamental purpose as bed plates but are typically smaller in size and can be mounted on a stand or frame to allow work to take place at a comfortable working height.

Surface tables can be fully customised in size, layout, and interface features to meet specific inspection and operational requirements.

Surfaces available plain, with T-slots or threaded interface features.
