Hot-dip Galvanizing Self-drilling Rock Bolts
The offering is hot‑dip galvanising self‑drilling rock bolts supplied by Luoyang Sinorock Engineering Material Co., Ltd. in Luoyang, Henan Province, China. These bolts are forged from carbon steel grades Q235 or Q355 and receive a hot‑dip zinc coating whose thickness normally lies between 43 µm and 85 µm. The self‑drilling shank allows direct installation into rock without pre‑drilling, and the product is presented as complying with ISO 1461 for hot‑dip galvanized coatings. The supplier indicates worldwide export capability, though no specific order quantity is listed.
In the mining and tunnelling sector, self‑drilling rock bolts commonly range from 12 mm to 30 mm in diameter and 1 m to 3 m in length, delivering tensile capacities of 400‑600 MPa for the underlying steel grades. The zinc coating, applied by hot‑dip, provides a protective barrier that meets the requirements of ISO 12944‑2 for environments with moderate to high corrosivity, giving an anticipated service life of more than 50 years when installed correctly. Typical bolt head designs include a socket or hex head, and the threads are cut to a standard pitch of 1.5 mm for 12‑mm diameter bolts. These characteristics enable reliable ground support in rock reinforcement projects.
Mining operators, geotechnical contractors and tunnel engineers are the primary buyers of these bolts, seeking long‑term corrosion resistance and rapid installation. Importers should request a sample to assess drilling performance and verify coating thickness before confirming bulk shipment. As the listing does not state a minimum order, buyers need to discuss quantity, Incoterms such as FOB Luoyang or CIF destination, and payment method, typically a letter of credit after inspection.

Luoyang Sinorock Engineering Material Co., Ltd. is located at No.1703, Building 3, No. 1 Fenghua Road, High‑Tech District, Luoyang, Henan Province, China. The company carries a harbor‑level verification tier on the marketplace, with a recorded response rate of 0 % and no average response time available.
The supplier has formulated its own standard for galvanized products in accordance with ISO 1461 and states that its rock bolts meet ISO 12944‑2 corrosion classifications. It offers worldwide export of these bolts but does not disclose additional certifications, years of operation or client references, so purchasers should request any required quality documents directly.
Hot-dip galvanizing self-drilling rock bolts are engineered for rock reinforcement in mining, tunneling, and slope stabilization projects. These zinc-coated bolts feature self-drilling capability for efficient in-situ installation, with the hot-dip process providing superior corrosion resistance in harsh underground environments. Exported globally for geotechnical contracting and mining operations, they meet international standards for load-bearing anchor systems.

Sourcing Hot-dip Galvanizing Self-drilling Rock Bolts from Luoyang Sinorock Engineering Material Co., Ltd. - China Import Guide
Before placing an order, importers should confirm that the bolts meet ISO 1461 and ISO 12944‑2 standards, and request coating‑thickness and tensile‑strength test reports. Verifying the zinc layer integrity and steel grade will ensure the bolts perform as expected in demanding underground environments.
Logistics for these bolts are usually arranged via sea freight from the Luoyang port, with common Incoterms such as FOB Luoyang or CIF the buyer’s destination. Buyers need to settle payment terms, often a letter of credit after a satisfactory pre‑shipment inspection, and discuss any MOQ requirements directly with the supplier.
Quality assurance should involve a visual check of the zinc finish, measurement of coating thickness, and a tensile test on a sample bolt. Engaging a third‑party inspection agency to validate compliance with the supplied certificates before loading can further reduce risk. Retaining documentation such as the mill test report and coating test certificate will aid customs clearance and future quality audits.
