Why Buy a Granite Measurement Table?

A granite measurement table is the ultimate stable reference surface for precision inspection,quality control,assembly,and metrology.With near-zero thermal expansion,superior vibration damping,and exceptional flatness,granite provides an unmatched foundation for accurate measurement that steel or cast iron cannot match.

Our Range of Granite Measurement Tables

1.STANDARD GRANITE SURFACE PLATES

The classic reference standard.Available in four accuracy grades:

Grade AA(Laboratory Grade):For calibration labs and high-precision inspection.

Grade A(Inspection Grade):For quality control departments(most popular).

Grade B(Toolroom Grade):For shop-floor layout and general reference.

*All plates include NIST-traceable calibration certificates with 3D flatness maps.*

2.GRANITE INSPECTION TABLES WITH GRID PATTERNS

Enhanced functionality with precision-drilled mounting holes:

Metric Grids:16mm or 28mm holes on 100mm centers

Imperial Grids:3/4"or 1"holes on 4"centers

Combination Grids:Mixed patterns for maximum flexibility

Perfect for modular fixturing systems and repeatable setups.

3.GRANITE ASSEMBLY&WELDING TABLES

Heavy-duty tables designed for fabrication:

Reinforced construction with steel substructures

Heat-resistant surfaces that won't warp or distort

Integrated clamping systems for secure workholding
