Haian Rubber Group Co., Ltd. (formerly Fujian Haian Rubber Co., Ltd.) was established in December 2005. As a manufacturer of giant all-steel OTR radial tires, it integrates R&D, manufacturing, sales, and mining tire operation management service. The Group’s headquarters is located in Putian City, Fujian Province, with over a dozen branches and subsidiaries at home and abroad. Among them, Fujian Haikuang Engineering Construction Co., Ltd. specializes in professional maintenance of mining trucks and earthwork projects, while some other subsidiaries undertake turnkey contract operation management of tire cost quotas for mining clients or engage in giant tire sales, and have made significant contributions to achieving cost reduction and efficiency gains, ensuring the safety and controllability of tire supply chains, improving the operating rate of mining vehicles for dozens of large and extra-large domestic and overseas mining enterprises—including central state-owned enterprises (CSOEs), local state-owned enterprises (SOEs), and more. These efforts have earned the group wide praise and trust from customers. Guided by technological innovation as its core driving force, Haian Group has consistently led the industry in groundbreaking advancements. In 2008, the company independently developed the 37.00R57 all-steel radial giant OTR tire, which was certified by the China Petroleum and Chemical Industry Federation as filling a critical domestic technological gap. This innovation resolved the long-standing "bottleneck" issue plaguing mining enterprises, achieved import substitution, was hailed by some authoritative media as “China’s First Tire”. It further secured the Second Prize of the Science and Technology Progress Award from the China Petroleum and Chemical Industry Federation in 2011. In 2015, Haian Group overcame technical challenges to produce the world’s largest all-steel giant tire—4.02 meters in diameter and weighing approximately 6 tons per unit—positioning China as the third nation globally capable of manufacturing such tires. This milestone earned the product the First Prize of the Science and Technology Progress Award from the same federation. With its robust product capabilities, Haian achieved a "zero breakthrough" in exports of nationally branded all-steel giant tires, and now the Luan tire is distributed to dozens of countries and regions.   Over years of development, Haian Group has crafted a scenario-specific product matrix covering specifications from 90 to 400 tons, catering to diverse operational needs of mining fleets. Its sales and service networks span hundreds of large-scale mines globally. According to industry reports, the group ranks #1 in terms of scale in China and #4 globally in the giant tire segment, trailing only three international giants, and is a core representative of Chinese giant tire brands expanding internationally.   Adhering to the development philosophy of "Science and technology are the primary productive force," Haian Group has consistently increased R&D investments and perfected its innovation ecosystem. It has established a National Postdoctoral Programme and Provincial Enterprise Technology Centre. The group has deepened collaborative research partnerships with universities, research institutions, and professional organizations, advancing the integration of industry, academia, and research to greater depths. To date, the company has accumulated over 90 patents. Contributed to the formulation of dozens of national, industry, and association standards, and earned honors including National High-Tech Enterprise, National Key "Little Giant" Enterprise (Specialised, Refined, Differential, and Innovative), Demonstration Enterprise for Service-Oriented Manufacturing, Top 100 Chinese Industrial Enterprises in Brand Competitiveness, National Leading Enterprise in Quality for the Chemical Industry, First Batch of Green Factories in Fujian Province, etc. These achievements reflect the continuous rise in Haian's brand strength and industry influence.   "Building a Conscience-Driven Brand, Empowering Mining Enterprises"has been Haian Group's enduring mission.
