Galvanized corrugated large-head nails are key metal components in the field of building fastening.

Galvanized corrugated large-head nails, as a key metal component in the field of building fastening, have been widely used in scenarios such as lightweight steel structures, industrial plants, storage facilities, and prefabricated buildings due to their excellent corrosion resistance brought by the galvanized coating and the stable anchoring advantage of the large-head structure. Currently, driven by multiple factors such as increased infrastructure investment in China, the deepening of green manufacturing policies, and the release of global emerging market demand, the industry has transitioned from a raw growth model to a new stage of high-quality development. As the world's largest producer and exporter, China's industry output value reached 8.6 billion yuan in 2024, with a production volume of approximately 1.42 million tons. Among them, green-certified products accounted for nearly 70%, and the premium price in the high-end market reached 8%-12%. The industry scale and quality level have simultaneously improved.
Policy regulation has established a full-chain development guidance, becoming the core driving force for industry transformation. At the national level, policies such as the "14th Five-Year Plan for Building Energy Conservation and Green Buildings" and the "Industrial Structure Adjustment Guidance Catalogue" have included high-strength and corrosion-resistant galvanized fasteners in the encouraged projects, requiring that the proportion of green building materials in newly built urban buildings should not be lower than 70% by 2025. At the local level, traditional industrial clusters such as Hebei and Jiangsu have introduced fiscal subsidy policies, providing 30% subsidies for equipment investment to enterprises that adopt clean production processes such as chrome-free passivation and water-based coatings. The standard system is continuously improving, with the new version of "General Technical Conditions for Building Impact Screws" adding mandatory indicators such as color coating adhesion and salt spray resistance. The product inspection pass rate reached 96.7% in the first half of 2025; the GB/T18226-2025 standard to be implemented in March 2026 further clarifies the requirements for the corrosion protection thickness of steel components, forcing enterprises to eliminate outdated production capacity.
The market demand structure has continued to improve, with the domestic and export markets growing in tandem. In the domestic market, the promotion of prefabricated buildings has become a core growth point. In 2024, the usage rate of galvanized corrugated large cap nails in the demonstration projects of the Ministry of Housing and Urban-Rural Development was 47 percentage points higher than that in traditional projects. Projects such as urban renewal and industrial plant expansion have released stable demand. According to estimates, the annual demand in the domestic industrial plant sector will reach 467,000 tons in 2025, with a year-on-year growth of 12%. In the international market, the entry into force of the RCEP has led to the gradual elimination of tariffs in the ASEAN market. In 2024, China's exports to ASEAN increased by 23.4%. The infrastructure boom in emerging economies such as the Middle East and Africa has driven the expansion of exports. The import share of Chinese-made galvanized corrugated large cap nails in countries like Saudi Arabia exceeds 50%. However, it is necessary to be vigilant about the certification barriers in the European and American markets. The EU requires that more than 75% of galvanized connectors provide an environmental product declaration in accordance with the EN 15804 standard. The "Buy American" policy in the United States has also raised the market access threshold.
Technological innovation and intelligent upgrading are reshaping the competitiveness of industries. At the process level, green technologies such as zinc-aluminum-magnesium alloy coatings and chrome-free passivation have achieved breakthroughs in domestic production. The salt spray test life has exceeded 1,200 hours, and the product tensile strength has reached over 680 MPa, which is 40% higher than that of traditional processes in terms of anti-corrosion performance. At the production end, the penetration rate of automated production lines has continued to increase. The application of multi-station cold heading machines and continuous hot-dip galvanizing systems has enabled each production line to reach a daily production capacity of 15 tons, with a production efficiency increase of over 20% and a defect rate controlled within 0.8%. Digital transformation is accelerating, with leading enterprises using MES systems to achieve full-process informatization from order scheduling, temperature control management to logistics distribution. Some enterprises have also established intelligent recycling systems to help achieve the goal of the Ministry of Industry and Information Technology of "reaching a 40% recycling rate of waste nails by 2026".
The industry still faces multiple challenges. The most prominent ones are the fluctuations in raw material prices and the increase in compliance costs. The price of zinc ingots has fluctuated by 42% over the past three years. The cost of environmental protection renovations has led enterprises to make an average annual investment of 3-5 million yuan. In the future, the industry will continue to transform towards greening, intelligence, and high-endization. It is expected that the market size will exceed 9.5 billion yuan in 2026, and the penetration rate of green and high-end products will exceed 75%. Enterprises need to focus on core technology research and development, improve the overseas certification system, and build a "raw materials - production - recycling" closed loop to seize the development opportunities brought by infrastructure expansion and the reconfiguration of the global supply chain.
