The scale exceeds 4.3 billion, and high-strength products and exports to Southeast Asia are driving growth in two ways.

I. Industry Positioning and Market Size
Galvanized corrugated nails are low-carbon steel fasteners with a surface treated by galvanization. Due to their anti-corrosion and corrosion-resistant properties, they are widely used in building roof connections, steel structure installations, and warehouse facility construction, etc. The domestic market size reached 12.566 billion yuan in 2024, and is expected to increase to 13.32 billion yuan in 2025, with a growth rate of 6%. The growth momentum comes from the promotion of new urbanization, the popularization of prefabricated buildings, and emerging demands such as photovoltaic brackets. In terms of production capacity, the total industry capacity is expected to reach 13.2 million tons in 2025, with an actual output of 11.8 million tons, and the capacity utilization rate remains at a high level of 89.4%.
II. Product Structure and Regional Layout
The mainstream products are those with a diameter of 4.8-6.3 millimeters and a length of 25-75 millimeters, accounting for more than 70% of the market share. The proportion of high-strength products has increased from 20.1% in 2024 to over 40% in 2025, and are widely used in heavy steel structure connections. In terms of technology, hot galvanization is the core technology, and the zinc liquid temperature needs to be precisely controlled at 440-460℃. Some enterprises have adopted environmentally friendly processes such as chrome-free passivation.
The regional distribution shows a "strong in the east and rising in the west" characteristic: The market size in the East is expected to be 4.42 billion yuan in 2025, accounting for 33.7%; the South and the North are respectively 3.05 billion yuan and 2.18 billion yuan; the Central and Western regions benefit from the acceleration of infrastructure construction, and their market share continues to increase, with the total expected to exceed 4 billion yuan in the Southwest and Northwest regions.
III. Competitive Landscape and Import/Export Trends
The industry concentration is gradually increasing, and the leading enterprises have prominent advantages: Jiangsu Dongcheng Tools is expected to have a sales volume of 1.36 billion yuan in 2025, with a market share of 10.2%; Jiangsu Guoli has an output capacity of 3.1 million tons, Zhejiang Jinding expands to 2.4 million tons, and the combined market share of the top three enterprises is close to 38%. Small and medium-sized enterprises focus on regional markets and use cost control as the core of competition.
The export market continues to expand, with an expected export volume of 197,000 tons in 2025, an increase of 5.9% compared to 2024. Southeast Asia is the core market (accounting for 45.2%), and the demand in the Middle East and Africa is growing at a rate of over 6%. The main export products are conventional galvanized specifications. The import volume is only 13,000 tons, mainly consisting of high-end customized products for use in precision manufacturing.
IV. Technical Trends and Development Challenges
Technical upgrades focus on intelligence and environmental protection: Leading enterprises introduce CNC presses and automated production lines, increasing production efficiency by 30% and product qualification rate to 99.8%; research and development of technologies such as vacuum galvanization and nano-coating are accelerating, with the corrosion resistance of the coating improving by more than 20%. At the same time, environmental protection policies prompt enterprises to upgrade processing equipment to reduce zinc liquid consumption and pollutant emissions.
The industry faces two challenges: Fluctuations in the price of galvanized steel wire as a raw material have led to an increase in the average product price from 2540 yuan per ton in 2024 to 2580 yuan per ton in 2025; changes in international trade policies and the insufficient R&D capabilities of small and medium-sized enterprises have constrained the high-quality development of the industry.
