ZongXiang Heavy Industry Machinery Co., Ltd., a leading manufacturer of mining and tunneling support equipment, has successfully completed the export of 5,000 pieces of 42mm split set stabilizers to Zambia. The shipment, finalized in late October 2025, marks another milestone in the company’s growing presence in the African mining sector, particularly in Zambia’s copper-rich Copperbelt Province.

The 42mm split set stabilizers, also known as friction rock bolts, are critical components in underground mine support systems. Made from high-strength steel tubing with a slit along its length, these stabilizers provide immediate ground support upon installation. When driven into a drilled hole slightly Smaller in diameter than the tube, the slit compresses, generating radial friction that anchors the bolt securely to the rock. This design ensures rapid stabilization of mine roofs and walls, enhancing safety and operational efficiency in challenging geological conditions.

The order was placed by a major Zambian mining contractor operating in the Copperbelt, a region renowned for its large-scale copper extraction activities. The client selected ZongXiang’s 42mm stabilizers for their proven durability, ease of installation, and cost-effectiveness. Each stabilizer measures 2.4 meters in length, with a wall thickness of 2.5mm and a yield strength exceeding 400 MPa, meeting international standards such as ASTM and ISO. The shipment included galvanized units to resist corrosion in Zambia’s humid underground environments.

ZongXiang’s production facility in Henan, China, mobilized its advanced rolling and welding lines to fulfill the order within a tight six-week timeline. Quality control teams conducted rigorous inspections, including dimensional checks, tensile strength tests, and surface finish evaluations, ensuring 100% compliance with the client’s specifications. The stabilizers were packed in durable wooden crates, with 50 pieces per crate, to withstand long-distance sea and road transport.

Logistics played a pivotal role in the project’s success. The shipment departed from Qingdao Port, transited through Durban, South Africa, and reached Lusaka via the North-South Corridor. ZongXiang coordinated with freight forwarders to navigate customs clearance in Zambia, ensuring all documentation, including certificates of origin and quality compliance, met regulatory requirements. The final leg of delivery to the mine site was handled by local transporters, with ZongXiang providing real-time tracking updates to the client.

This export underscores ZongXiang’s commitment to supporting Africa’s mining industry. Zambia, the continent’s second-largest copper producer, relies heavily on robust ground control solutions to maintain productivity in its deep underground mines. Split set stabilizers are ideal for the region’s variable rock formations, offering flexibility and reliability where traditional rock bolts may underperform. The 5,000-piece order is expected to support multiple tunneling and stope development projects, contributing to safer working conditions for thousands of miners.

ZongXiang’s regional manager, Li Wei, expressed pride in the partnership: “Zambia’s mining sector demands high-quality, dependable equipment. Our 42mm split set stabilizers are engineered to exceed these expectations, and this shipment reflects our ability to deliver on a large scale.” The client’s project engineer praised the product’s performance during on-site trials, noting reduced installation time and enhanced roof support compared to previous suppliers.

The transaction also highlights ZongXiang’s streamlined export process. From order confirmation to delivery, the company provided end-to-end support, including technical consultations, customized packaging, and after-sales guidance. Training materials on proper installation techniques were included to ensure optimal use of the stabilizers.

This export strengthens ZongXiang’s footprint in Southern Africa, where demand for mining support products continues to grow. The company has already received inquiries for additional orders from Zambian and neighboring Congolese operators. By combining innovative manufacturing with reliable logistics, ZongXiang is poised to play a vital role in the region’s mining infrastructure development.

As Zambia pushes to expand copper output to meet global demand for electric vehicles and renewable energy technologies, partnerships with suppliers like ZongXiang will be crucial. The successful delivery of 5,000 42mm split set stabilizers not only reinforces operational safety but also cements ZongXiang’s reputation as a trusted partner in Africa’s mining future.
