The scale has been expanded to 4.5 billion, driven by a dual force of technological upgrading and export growth.

I. Industry Positioning and Market Size
The large-head cap rivets, with their large head size and uniform force distribution, are mechanical fasteners that feature a neat appearance after installation and resistance to bumps. They are widely used in various connection scenarios across multiple fields. From 2018 to 2023, the compound growth rate of the opening core-pulling large-head cap rivets market in China reached 7.5%, and it is expected that the market size will exceed 5 billion yuan in 2025, with a global share expected to rise to 40%. Among them, stainless steel materials dominate, with the combined share of 304 and 316 series exceeding 78%. High-end products have seen significant growth due to their performance advantages.
II. Product Classification and Technical Characteristics
Products are classified by performance into ordinary type, high-strength type, and corrosion-resistant type. New self-drilling and self-tapping products are rapidly emerging. Materials include steel, aluminum, copper, and titanium alloys, etc. Aluminum-based large-head rivets are known for their lightweight and corrosion resistance, while stainless steel products dominate the construction and rail transportation fields due to their strength advantage. Technological upgrades focus on two aspects: process-wise, electroplating without cyanide and micro-arc oxidation treatment are adopted to extend the salt spray resistance time to 3000 hours; detection-wise, visual systems are used to achieve 0.05mm internal size precision control.
III. Industry Chain and Cluster
The upstream relies on raw material supplies such as stainless steel wire, while the midstream is concentrated in clusters in East China and South China - Wenzhou, Zhejiang, has over 300 enterprises, accounting for 35% of the national total; Wuxi, Jiangsu, is known for its high-end manufacturing, introducing German and Japanese precision equipment to achieve efficient production. Leading enterprises such as Jiangsu Baoli and Zhejiang Yongxing have shortened the delivery cycle by 30% through digital management systems, and the CR5 (concentration of the top five enterprises) is on the rise. Downstream demand drives industry upgrading, and end customers have incorporated low-carbon certification into their procurement standards.
IV. Core Application Scenarios Expansion
The demand in traditional construction accounts for over 40%, mainly used for curtain wall and floor fixation; for new energy vehicles, due to the demand for lightweight, the purchase volume of sealed large-head rivets has increased significantly; in the rail transportation field, products are required to have anti-loosening structures and special coatings to cope with the aerodynamic pressure during high-speed operation. In emerging markets, the demand for photovoltaic brackets for nails has increased by 42%, and the demand for 5G base station fastening components has increased by 18% annually, becoming new growth poles.
V. Development Trends and Challenges
The industry is transforming along three directions: in terms of intelligence, the coverage of digital factories has risen to 28%, and robot and Internet of Things technologies are widely applied; in the green field, the proportion of cyanide-free processes has reached 30%, and the utilization rate of recycled stainless steel continues to increase; in terms of global layout, the export to the ASEAN market has increased by 14.6%, and the proportion of overseas orders will reach 31%. However, raw material price fluctuations and environmental protection investment pressure still exist, and enterprises need to break through bottlenecks through strategic reserves and technological research and development.
