Recently, as an important subcategory in the metal fastener field, the steel flat and smooth nail industry has shown a distinct development trend of "stabilizing growth, adjusting structure and improving quality" under the multiple drivers of policy guidance, technological upgrading and market demand. From market size to technological innovation, from domestic demand to overseas expansion, the industry is undergoing a crucial transformation from scale expansion to high-quality development.
At the market level, the industry maintains a steady growth resilience. Data shows that the market size of China's stainless steel large flat head machine nails (the core category of steel flat and smooth nails) reached 8.73 billion yuan in 2024, increasing by 6.2% year-on-year. It is expected to rise to 9.27 billion yuan in 2025, with a stable growth rate. This growth is attributed to the continuous expansion of downstream application scenarios. The demand in traditional fields such as architectural decoration and furniture manufacturing has been steadily released. Emerging scenarios like the fixation of new energy vehicle battery packs and the installation of photovoltaic brackets have become the core of the increment. The market size of related supporting fasteners is expected to increase by more than 20% year-on-year in 2024. In terms of regional distribution, East China and South China remain the core industrial areas. Jiangsu, Zhejiang and Guangdong provinces contribute over 65% of the national production capacity, and the cluster effect of industries continues to be prominent.
Policy and standard upgrades have become important drivers for the standardized development of the industry. In September 2025, the National Technical Committee for Standardization of Hardware Products officially launched the revision work of the national standard "Steel Nails", clearly integrating scientificity, forward-looking and applicability into the new standard, with a focus on regulating the mechanical properties, environmental protection indicators and testing methods of the products. Meanwhile, policies such as the "Green Building Action Plan" have forced the industry to undergo a green transformation. Environmentally friendly processes like Dacromet coating and mechanical galvanizing have gradually replaced traditional electroplating. Leading enterprises have achieved a 11.4% reduction in energy consumption per unit of product.
Technological innovation and intelligent manufacturing are accelerating the resolution of industry pain points. Facing the pressure of fluctuating raw material prices, enterprises have enhanced their competitiveness through process upgrades: After the cold heading - thread rolling integrated production line was optimized by digital twin technology, the production cycle rate increased from 198 pieces per minute to 236 pieces per minute, and the yield rate remained stable at over 99.5%. In the field of materials, the application of high-strength cold heading steels such as ML35CrMo has increased the fatigue life of products by 32%, and the Dacromet composite coating has exceeded the salt spray corrosion resistance time by 520 hours, meeting the demands of high-end scenarios. In addition, the popularization of ERP management systems and intelligent warehousing has enabled leading enterprises to achieve precise order matching and full control over the entire production process.
The expansion of the export market has injected new vitality into the industry. Benefiting from the infrastructure demand along the "Belt and Road Initiative", the export value of large flat head stainless steel machine nails in China increased by 8.3% year-on-year in 2024, mainly sold to Southeast Asia, the Middle East and Africa markets. The structure of export products has been continuously optimized. The proportion of high value-added products that meet international standards such as ISO and ASTM has exceeded 75%, and the export income of enterprises like Zhejiang Dongming has reached 54%.
Although the current industry is confronted with the challenge of fluctuating prices of raw materials such as nickel and chromium, structural opportunities have already emerged. Enterprises with precision manufacturing capabilities, international certification qualifications and green production levels are gradually occupying the competitive high ground. With the improvement of the standard system and the acceleration of technological iteration, the steel flat and smooth nail industry will continue to forge ahead on the path of high-quality development.
