In 2025, China's scale will reach 13.3 billion, and the chromium-free process and exports to ASEAN will become growth highlights.

I. Product Positioning and Core Characteristics
Galvanized corrugated nails are industrial fasteners made of low-carbon steel and treated with galvanization. The nominal diameters range from 2.8 to 4.2 mm, and the lengths cover 20 or more specifications such as 38-120 mm. Their core advantage lies in corrosion resistance. Products meeting the GB/T15856.3-2018 standard can withstand salt spray tests for 720 hours without rusting. They also possess high strength, making them key materials for connecting wooden components and fixing roof surfaces. They are indispensable in the fields of construction and packaging.
II. Market Size and Growth Momentum
The industry will show a steady expansion trend in 2025. The market size in China is expected to reach 13.32 billion yuan, with a year-on-year growth of 6%. The output will exceed 1.65 million tons. The growth momentum comes from three aspects: policy side, the "14th Five-Year Plan for the Construction Industry" requires that the proportion of prefabricated buildings reach 30% in 2025, which will drive a significant increase in the demand for special nails; demand side, the total output value of the construction industry is 3.21 trillion yuan, and the proportion of steel structure buildings has increased, directly driving the demand; export side, the export volume exceeded 120,000 tons in 2023, with a 34% share in the Southeast Asian market, and an average annual growth rate of 23%.
III. Demand Structure and Regional Characteristics
The application fields are highly concentrated. The construction industry accounts for over 62%, and the single-project usage density of prefabricated buildings is 40% higher than that of traditional construction. The procurement scale in 2025 will exceed 1.8 billion yuan. The packaging field accounts for 25%, and the development of e-commerce logistics has directly driven the demand growth. The emerging field of new energy has seen an increase in annual demand for photovoltaic support structures of approximately 80,000 tons. The consumption in the regions is as follows: the combined consumption in the East and South China accounts for 48.6% of the national total, the production in the Yangtze River Delta accounts for 38.7%, and the major projects in the Guangdong-Hong Kong-Macao Greater Bay Area create a demand of 230 million yuan per year. The growth rate in the central and western regions has exceeded the national average for three consecutive years by 2 percentage points.
IV. Technology Upgrade and Industry Transformation
The products are evolving towards high-endization. Hot-dip galvanization products are the mainstream, accounting for over 65%. New technologies such as zinc-magnesium-aluminum ternary alloy coatings have enhanced the corrosion resistance by 40%. The environmental transformation is accelerating, with the penetration rate of chrome-free passivation processes reaching 35% in 2025. The market share of this type of product in coastal areas has reached 30%, and the export unit price is 28% higher than that of ordinary products. The production end is upgrading with intelligentization, with leading enterprises having built automated production lines, with a daily production capacity of 15 tons per line, and digital transformation has increased the per capita output to 2.3 times the industry average.
V. Competitive Landscape and Development Challenges
The market presents a "large enterprises dominate, small and medium-sized enterprises supplement" pattern. Hebei contributes 34% of the national output, but the capacity utilization rate of small and medium-sized enterprises is only 68%. Enterprises in Shandong and Sichuan have risen through technological transformation, and enterprises such as Qingdao Jin Anchor have established advantages through intelligent workshops. Current challenges are significant: raw material cost fluctuations affect profitability, there are shortcomings in the high-end field, and at the same time, they need to cope with the pressure of stricter environmental policies. However, the RCEP benefits and digital transformation provide breakthrough opportunities for the industry.
