Henan ZongXiang Heavy Industry Import & Export Co., Ltd., a leading Chinese manufacturer and supplier of mining support products, has successfully exported a batch of 33mm split set bolts to Tanzania, reinforcing its position as a trusted global supplier in the mining industry. Established in 1997, ZongXiang, a subsidiary of Zhongxiang Steel Group, specializes in high-quality mine support products, including split set stabilizers, rock bolts, and wire mesh, catering to both domestic and international markets. This recent export underscores the company’s commitment to providing reliable, high-performance solutions for underground mining operations.

The 33mm split set bolt, also known as a friction bolt or stabilizer, is a critical component in hard rock mining, widely used for ground support in underground excavations. These bolts are made from high-yield, high-strength carbon steel, such as Q235 or 20MnSi, with a thickness ranging from 2.0 to 3.0mm. The design features a slotted metal tube that, when driven into a slightly smaller pre-drilled borehole, generates axial and radial frictional forces against the rock strata, ensuring robust anchoring and roadway safety. ZongXiang’s 33mm split set bolts are engineered for durability, with a retaining ring weld pull-out force exceeding 80kN, a rod ultimate tensile strength above 110kN, and an initial anchoring force of at least 25kN/m. The bolts are non-galvanized, adhering to GB standards, and are tailored for applications in copper, gold, and other hard rock mines.

Tanzania, with its thriving mining sector, particularly in gold and base metals, presents a growing demand for reliable ground support systems. ZongXiang’s export of these bolts addresses this need, offering Tanzanian mining operations a cost-effective and easy-to-install solution. The bolts are driven into place using pneumatic jackleg drills equipped with specialized split set drivers, ensuring seamless integration into existing mining workflows. ZongXiang’s ability to produce up to 50,000 pieces daily, combined with its large inventory and advanced manufacturing facilities spanning 33,000 square meters, ensures timely delivery and consistent quality for international clients.

This export aligns with ZongXiang’s broader mission to deliver high-quality mining support products globally. The company’s extensive experience, supported by four modern production sites and a dedicated R&D team, ensures that its products meet rigorous industry standards, as evidenced by ISO9001 and ISO45001 certifications. ZongXiang’s split set bolts have been well-received in other markets, including South Africa, Ghana, Zambia, and Indonesia, highlighting their versatility and reliability. By exporting to Tanzania, ZongXiang strengthens its presence in East Africa, contributing to safer and more efficient mining operations.
