Henan ZongXiang Heavy Industry Import & Export Co., Ltd., a cornerstone of the Zhongxiang Steel Group since 1997, has cemented its global reputation by exporting 2,000 pieces of 15.2mm cable bolts to India in October 2025. With an annual output surpassing US$100 million and a workforce of over 100, ZongXiang specializes in mine tunnel support systems, including rock bolts, steel arches, and wire meshes. Operating from advanced facilities in China, the company ensures high-quality production for demanding mining environments worldwide.

This significant order, destined for a leading Indian mining consortium, addresses the growing need for robust strata reinforcement in India’s coal and metal ore sectors. The 15.2mm cable bolts, crafted from high-strength, low-relaxation 7-wire steel strands, boast a tensile strength of 1860 MPa. Designed for long-tendon applications, these plain cable bolts enhance roof and rib stability in underground mines, mitigating rockfall risks in India’s diverse geological conditions, from Odisha’s coal seams to Karnataka’s hard rock formations.

The export process began with close collaboration between ZongXiang’s engineers and the Indian client’s geotechnical team. Tailored to comply with Indian Bureau of Mines standards, the bolts support easy installation through tensioning and grouting, ensuring optimal load transfer. The order, totaling approximately 40,000 meters (assuming 20-meter lengths), was manufactured in three weeks at ZongXiang’s 30,000-square-meter facility. Rigorous quality checks confirmed compliance with ISO 9001 and ASTM standards, guaranteeing durability in humid, high-stress environments.

Logistics were meticulously planned. On October 7, 2025, the consignment shipped from Qingdao Port, arriving in Chennai on October 12 via an optimized Belt and Road Initiative route, cutting transit costs by 12%. ZongXiang’s Kolkata liaison office streamlined customs clearance, adhering to international trade protocols like ISPM 15. The five-day transit underscores ZongXiang’s logistical prowess, leveraging established shipping networks to ensure timely delivery.

This export aligns with India’s mining sector growth, projected at 7.8% annually through 2030, fueled by infrastructure and renewable energy demands. The bolts will support a major coal project in Dhanbad, stabilizing 50,000 square meters of tunnel roof. Initial trials report a 22% improvement in anchorage performance compared to traditional bolts, attributed to ZongXiang’s optional spiral rib designs, which enhance energy absorption during seismic activity.

ZongXiang’s innovation extends to R&D, with anti-corrosion coatings tailored for India’s monsoon-prone regions. This shipment is part of a broader South Asian expansion, with planned exports to Sri Lanka and Bhutan. By offering just-in-time delivery and technical support, ZongXiang fosters enduring partnerships. This milestone highlights their role in global mining safety, where their cable bolts serve as critical lifelines, reinforcing tunnels and economies alike.
