As the "metal joint" in the industrial field, the galvanized screw industry has recently shown a development trend of coexisting steady growth and structural upgrading under the dual impetus of policy guidance and market demand. The latest industry data shows that the market size of China's hot-dip galvanized bolts (including screws) industry reached 102.5 billion yuan in 2024, with a year-on-year growth of 2.5%. It is expected to exceed 105 billion yuan in 2025, maintaining a steady growth momentum.
The expansion of infrastructure and the new energy industry has become the core engine driving demand growth. Under the impetus of the 14th Five-Year Plan, investment in railway and highway construction across the country has continued to increase. In 2024, investment of 720 billion yuan and 2,450 billion yuan will be completed respectively, directly driving the demand for high-strength galvanized screws. The wind power sector performed particularly well, with the annual demand increasing by 12% year-on-year. The galvanized fasteners applied in a wind farm in Northwest China successfully withstood the tests of a 50℃ temperature difference and sandstorms, achieving a record of zero loosening. In the regional market, the East China region, with a scale of 32 billion yuan, accounts for 31.2% of the market share. The combined share of South China and North China exceeds 44%, forming three core consumption regions.
Environmental protection policies have forced the industry to undergo green transformation, and the results of technological upgrading have been remarkable. In 2024, the environmental protection standards for the national hot-dip galvanizing industry will be further raised. 47 enterprises that fail to meet environmental protection standards will exit the market, promoting an increase in the industry's concentration. Against this backdrop, the number of enterprises adopting environmentally friendly zinc coating treatment technology has increased by 18% year-on-year. The chromium-free sealed galvanized products launched by enterprises such as Zhenxin Factory have achieved a salt spray test duration exceeding 1,000 hours, and their anti-corrosion performance is three times better than that of ordinary products. In terms of international standards, the ASTM F1941-16 (re-approved in 2025) specification is implemented, clarifying the anti-corrosion requirements for different coatings. Among them, the red rust appearance time of the zinc-nickel alloy coating can reach 500 hours, making it the preferred choice in the high-end market.
The import and export market shows the characteristic of "coexistence of external demand growth and barriers". In 2024, the total export volume of the industry reached 8.6 billion yuan, increasing by 4.1% year-on-year. Southeast Asian countries such as Vietnam and Indonesia became the main destinations. However, trade barriers such as the adjustment of anti-dumping duties by the European Union and relevant investigations by Canada have increased export costs by 15%. Meanwhile, the high-end market still relies on imports. Customized products from Japan and Germany account for 1.43 billion yuan of the import market, and there is a vast space for domestic substitution.
The current industry is shifting from scale expansion to quality competition, and the advantages of leading enterprises are becoming more prominent. The top ten enterprises, including Jiangsu Zhongtian Technology and Zhejiang Wanxiang, collectively hold a 35% market share. Their R&D investment has been continuously increasing. In 2024, the industry's R&D expenditure reached 2.86 billion yuan, representing a year-on-year growth of 7.2%. With the advancement of the "Belt and Road Initiative" infrastructure and breakthroughs in domestic high-end fastener technology, the galvanized screw industry will achieve higher-quality development in green manufacturing and global layout.
