Import Granite Inspection Surface Plate — Buy in Bulk from Supplier in China

The Granite inspection surface plate offered by Jinggong Measuring Tools Producing Co., Ltd. is a precision measurement platform fabricated from natural granite. The plate features a finely polished surface that delivers minimal deviation and provides thermal stability for consistent readings. It is supplied in a variety of sizes and thicknesses to match different workshop requirements, and each unit includes adjustable leveling feet for quick set-up. The granite composition ensures resistance to wear in demanding industrial environments.

Granite used for surface plates typically conforms to grade A stone with a compressive strength above 150 MPa and a water absorption below 0.5 %. Industry standards call for a flatness tolerance of about 0.5 µm per 100 mm and a surface roughness Ra of 0.8 µm, which the supplier’s polishing process aims to achieve. The thermal coefficient of granite is usually around 7 ppm/°C, allowing the plate to maintain dimensional accuracy across temperature variations. These characteristics make the plate suitable for high-precision setups in aerospace, automotive and metal-working sectors.

Typical buyers are quality-control engineers, metrology labs and manufacturers that require reliable inspection tooling. Jinggong can ship the plates on FOB or CIF terms, and the company notes that flexible minimum order quantities are available, though exact limits should be confirmed directly. The product is supplied with the certifications required for measurement equipment, and buyers are encouraged to request the specific certificates relevant to their market. Payment and logistics details are negotiable per order, and the supplier’s response metrics indicate that inquiries may require follow-up.
