Granite surface plate and machinery parts

Jinan Best Up Import & Export Co., Ltd. manufactures granite surface plates and related machinery parts in China. The catalogue covers dimensions from a compact 300 mm × 200 mm plate up to a large 8000 mm × 3000 mm format. Each plate is produced to high precision and conforms to the Chinese JB/T, German DIN, Japanese JIS and American ASME standards. The company ships the items in sturdy wooden cases to protect the flat surfaces during transit.

Granite plates of this class are typically fabricated from 99 % aluminium oxide granite, which provides excellent dimensional stability. In the industry a flatness tolerance of 0.02 mm per metre is common for precision work, and a surface roughness Ra of around 0.8 µm is considered adequate for inspection and assembly tasks. Standard thicknesses range from 25 mm to 40 mm, and load‑bearing capacity is usually specified at about 500 kg for a 1000 mm × 500 mm plate. These typical figures help buyers compare performance across suppliers, while the supplier’s own plates meet the same benchmarks.

The plates are used by machine shops, calibration laboratories and aerospace manufacturers that require repeatable measurement surfaces. Jinan Best Up can also produce plates to a customer’s CAD drawing, offering custom dimensions or special tolerances on request. Prospective importers should confirm minimum order quantities, incoterms and payment terms directly with the supplier before placing an order.

Jinan Best Up Import & Export Co., Ltd. is located at Erhuan Rd 3966, Jinan, Shandong, 250100, China. The supplier is listed with a harbour trust tier, and its platform response metrics show a 0.00 % response rate with no recorded response hours. These signals indicate that communication may require proactive follow‑up.

The company supplies granite surface plates ranging from 300 mm × 200 mm to 8000 mm × 3000 mm and can also manufacture parts to a buyer’s drawing or special requirement. All items are packed in wooden cases, and the catalogue references compliance with JB/T, DIN, JIS and ASME standards, providing a clear baseline for quality expectations.
