The product is a left‑hand rock bolt supplied by Henan Zongxiang Heavy Industry Import And Export Co, .ltd. It is fabricated from high‑strength low‑alloy steel grades 16Mn and 20MnSi. Standard diameters are 16 mm and 18 mm, with lengths offered at 2 m and 6 m, and custom sizes can be requested. The bolts feature left‑hand threading to match conventional mining equipment.
The steel is hot‑rolled, giving uniform tensile properties along the full length and eliminating the need for machining at either end. In the mining industry, such low‑alloy steel bolts are preferred for their high material utilization and reliable anchoring force. Typical tensile strength for these grades is around 1500 MPa, while yield strength is about 1200 MPa. The bolts are supplied with a prestressed gasket to aid installation quality.
These bolts are used for underground coal mining, tunnel construction and other geotechnical projects where rock reinforcement is required. Bulk export orders are accepted, and buyers should confirm the exact dimensions, packaging and incoterms before purchase. Trade terms such as MOQ, payment method and lead time are negotiated directly with the supplier.

Before placing an order, importers should obtain the product data sheet confirming the steel grade, diameter, length and thread direction. Request a sample batch or certification that records tensile test results against the stated typical values. Verify that the left‑hand threading matches the equipment used on site and that the prestressed gasket is included as described.
Discuss shipping arrangements early, specifying the preferred incoterm such as FOB Zhengzhou port or CIF Shanghai, and ask the supplier to quote the estimated lead time for the requested dimensions. Because the supplier’s response rate is currently low, allow extra time for correspondence and confirm the payment method, typically a T/T advance or a letter of credit. Clarify whether the bolts will be palletised or bundled in bulk crates for sea freight.
Arrange an independent third‑party inspection prior to loading, focusing on dimensional compliance, thread integrity and surface condition. Ask for a mill test report, material certificate and a compliance statement with the applicable ASTM standard. Maintaining records of these documents will facilitate customs clearance and ensure that the delivered bolts meet the project’s safety requirements.
