Screw Steel Bolt
The Screw Steel Bolt offered by Henan Zongxiang Heavy Industry Import And Export Co, .ltd. is a high‑strength rock bolt intended for roadway reinforcement in underground coal mines. It is manufactured from alloy steel grades 16Mn or 20MnSi, providing the tensile capacity required for self‑supporting rock structures. The listing cites two standard sizes - 18 mm × 2 m and 16 mm × 6 m - and notes that both standard and custom dimensions are available upon request.
These bolts conform to GB/T and MT Chinese standards, which define mechanical performance, thread geometry and corrosion‑resistance requirements for mining applications. Typical tensile strength for the 16Mn grade is around 900 MPa, while 20MnSi offers slightly higher values, ensuring reliable load‑bearing capacity. A zinc galvanised coating is normally applied as a standard protective finish to mitigate underground corrosion, and the threaded design enables rapid installation with standard drilling equipment.
Mining companies and underground construction firms source this bolt for its durability and ease of installation. Buyers should confirm the exact quantity needed, as the listing does not disclose a minimum order quantity, and negotiate bulk packaging on wooden pallets for export. Shipping is arranged from inland factories in Zhengzhou, with Incoterm and payment terms to be agreed directly with the supplier. Lead‑time estimates must be obtained from the supplier before finalising the order.

Sourcing Screw Steel Bolt from Henan Zongxiang Heavy Industry Import And Export Co, .ltd. - China Import Guide
Verify the alloy grade, tensile‑strength test reports and coating specifications before confirming an order, and request a material certification sheet that references the GB/T and MT standards cited. Ensure the supplier can provide the necessary export documentation, such as a certificate of origin and a product conformity declaration, to satisfy customs requirements in your destination country.
Shipping will typically depart from Zhengzhou to a major Chinese seaport such as Shanghai or Ningbo; discuss expected lead times, freight options and preferred Incoterms with the supplier. Payment terms are not disclosed, so negotiate conditions that align with your company’s risk management policy, for example a documentary letter of credit for first‑time orders.
For large volume purchases arrange a third‑party inspection focused on bolt dimensions, thread accuracy and coating integrity. Request the supplier’s ISO quality‑management certificate, corrosion‑resistance test results and any relevant mining‑safety certifications to ensure the product meets your project’s technical and regulatory standards.
