About ISO Certified Granite Surface Plate

Granite Surface Plates are highly precise inspection and measurement tools widely used in engineering industries for accurate layout, marking, and quality control applications. Manufactured from premium-grade natural black granite, these plates provide exceptional surface accuracy, rigidity, and long-term dimensional stability.

Our Granite Surface Plates are processed using advanced cutting, seasoning, and lapping techniques to achieve superior flatness and surface finish. The inherent properties of granite, such as non-corrosiveness, non-magnetic nature, and resistance to wear, make these plates more reliable compared to conventional cast iron surface plates.

These plates are ideal for use in inspection departments, tool rooms, research laboratories, and precision manufacturing industries including automotive, aerospace, heavy engineering, and fabrication units.

Each plate is manufactured and calibrated as per international standards and is available in different grades such as Grade 0 (Inspection Grade), Grade 1 (Tool Room Grade), ensuring suitability for various precision requirements.

Material: Natural Black Granite
Grades Available: Grade 0, Grade 1,
Surface Finish: Precision lapped
Standard Sizes: Available in multiple sizes (custom sizes also available)
Accuracy Standards: As per DIN / IS / ISO standards

Support System: Optional fabricated stand with leveling screws

Engineered for Precision and Stability

Every granite surface plate is lapped to achieve optimum flatness and adheres strictly to ISO 8512-2 and IS 7327-2003 standards. The non-magnetic, hard black granite resists thermal expansion and wear, ensuring reliable accuracy over countless operations. Ideal for precise industrial measurements and delicate tool calibration.

Robust Construction and Versatile Sizing

Manufactured from high-quality black granite, the plates offer exceptional strength and resistance to corrosion. Standard plate thickness ranges from 150 mm to 300 mm and can be customized up to 3000 x 2000 mm or larger. Each plate can be supplied with or without a powder-coated mild steel stand for flexibility in setup.

Certification and Accessories for Ease of Use

Every plate comes ISO Certified and includes standard accessories such as levelling screws or feet, and a calibration chart. Custom sizes and edge designs (chamfered or square) are available on request, making the product adapt seamlessly to diverse workshop or laboratory needs.

FAQ's of ISO Certified Granite Surface Plate:

Q: How is the flatness of the granite surface plate ensured and certified?

A: Each granite surface plate undergoes precision lapping and rigorous inspection as per ISO 8512-2 and IS 7327-2003 standards. A calibration chart is provided with each plate, certifying its flatness and accuracy grade (0, 1, or 2), ensuring compliance with industry requirements.

Q: What are the main benefits of using a granite surface plate in an industrial setting?

A: Granite surface plates provide a stable, non-deformable, and wear-resistant base for precision measurement and tool inspection. Their non-magnetic and corrosion-resistant properties ensure long-term durability, while the low thermal conductivity minimizes expansion and measurement error.

Q: When should the granite surface plate be recalibrated?

A: It is recommended to recalibrate the surface plate annually or after heavy usage, relocation, or significant temperature/humidity fluctuations. Regular recalibration ensures sustained accuracy consistent with ISO and IS standards.

Q: Where can these granite surface plates be used most effectively?

A: These plates are ideal for industrial laboratories, inspection rooms, precision machining workshops, and toolmaking environments. Their stability and precision make them suitable wherever high-accuracy measurement and repeatability are required.

Q: What is the custom sizing and accessory process for a granite surface plate order?

A: Customers can specify required dimensions, edge types (chamfered or square), and the need for optional stands or levelling accessories when placing orders. The manufacturer provides plates tailored to individual requirements, also supplying a calibration chart and installation instructions.

Q: How does the granite plate withstand environmental conditions like humidity and temperature changes?

A: The black granite used is highly stable, with low thermal conductivity and non-porous properties. This ensures minimal expansion or contraction due to temperature changes (recommended 16C-28C) and reliable performance in humidity levels up to 80%.
