The product is a cast iron grinding surface plate supplied by Jinggong Measuring Tools Producing Co., Ltd. It is made from gray cast iron with a flake graphite structure containing carbon 3.0‑3.3%, silicon 2.0‑2.5% and manganese 0.5‑0.8%. The plates are offered in grades A and B and conform to GB/T 4986 and GB/T 23631 standards. Size options run from 100 mm × 100 mm up to 3000 mm × 8000 mm, with larger dimensions possible on drawing request.
These plates use high‑strength gray cast iron GG20‑GG30 (HT200‑300), a material favoured in precision metrology for its dimensional stability and wear resistance. Typical industry practice expects a flatness retention of about 0.02 mm per metre and a surface roughness around Ra 0.8 µm, while hardness usually lies between HB 200 and HB 250. The flake graphite microstructure provides good damping and reduces distortion during repeated grinding cycles, making the plates suitable for long‑term use in tool rooms and laboratories.
The plates are primarily employed in tool rooms, workshops and laboratories for inspecting dimensions, calibrating measuring instruments and grinding high‑precision components. Buyers such as precision engineering firms, optical instrument manufacturers and machine tool producers value the stable reference surface they provide. The items are packed in reinforced wooden crates for safe international transit; interested importers should contact the supplier to confirm minimum order quantities, lead times and preferred Incoterms.

Before placing an order, verify that the material grade, size and compliance with GB/T 4986/GB/T 23631 are documented on a mill test certificate. Request samples of the packaging arrangement and confirm that the crate dimensions suit your freight forwarder’s handling equipment. Clarify any special surface‑finish requirements and whether the supplier can provide a surface‑roughness report.
Logistics for these heavy iron plates typically involve sea freight; however the exact lead‑time is not listed, so importers should ask the supplier for an estimated production schedule and preferred Incoterms such as FOB Shanghai or CIF Shanghai. Payment terms are also not disclosed, making it prudent to negotiate a letter of credit or escrow arrangement that aligns with the shipment milestones.
Quality assurance should include a factory inspection focusing on material homogeneity, flatness measurement and surface‑finish verification. Request a third‑party inspection report or arrange your own audit before loading. Ensure the supplier can supply calibration certificates, hardness test results and any relevant conformity documentation to satisfy your downstream quality control process.
