In 2024-2025, the output of electro-galvanized steel wire industry will exceed 4.1 million tons, and the regional structure will be optimized

I. Core Product Characteristics and Process Advantages
The electro-galvanized steel wire is electroplated with zinc layer on its surface through a normal temperature electrolysis process. The thickness of the zinc layer can be precisely controlled within the range of 5 to 20 micrometers, featuring excellent corrosion resistance and mechanical stability. Its core advantages lie in that the electroplating process does not damage the original mechanical properties of the steel wire, avoiding the hydrogen embrittlement problem that may occur with hot-dip galvanizing, with an ultimate tensile strength of up to 2400 megapascals. Additionally, the surface is smooth and free of burrs, suitable for subsequent processing such as drawing and weaving. Customized coating schemes can be provided based on application scenarios: for humid environments, chrome salt passivation treatment is adopted to enhance the anti-white rust ability; in the environmental protection field, silane-based non-chrome passivation technology is promoted, with a year-on-year growth rate of 15% for the enterprises currently using this technology. This multi-functional adaptability makes it indispensable in high-end manufacturing.
II. Market Size and Demand Structure
The market size of electro-galvanized steel wire in China reached 78.5 billion yuan in 2024, increasing by 10.56%, and is expected to reach 86 billion yuan in 2025. The demand shows significant structural characteristics: the construction sector accounts for over 45%, with a market size of 35.3 billion yuan; the power and communication sector accounts for 27.0%, reaching 21.2 billion yuan; driven by the growth of new energy vehicles, the demand for automotive products has increased by 12.7%, with a scale of 13.8 billion yuan.
In terms of regional distribution, the East China region dominates the market with a 38% share, while the central and western regions have a growth rate of 13.2%, becoming new growth poles. In terms of product specifications, the 0.5-2.0mm medium wire accounts for 54.8% and is the most widely used category. The 0.5mm and below fine wire is driven by the demand in electronic communication, with a growth rate expected to reach 11.9%.
III. Technological Upgrade and Industry Transformation
The production end has achieved key technological breakthroughs: the continuous electroplating process and the automated tension control system have seen a significant increase in popularity, promoting dual improvements in product quality and consistency. The acceleration of high-end product research and development has led to the penetration rate of zinc-copper alloy-coated steel wire in the field of battery fixation for new energy vehicles reaching 31%, an increase of 1.6 times compared to three years ago.
The industry concentration has continued to increase, with the market share of the top ten enterprises exceeding 52% in 2024. Head companies such as Baosteel and Falusheng dominate the high-end market with their technological advantages. Environmental protection policies have become an important driving force. The "Manufacturing High-Quality Development Action Plan" promotes the industry towards green transformation, with the proportion of environmentally friendly products expected to reach 28% in 2025.
IV. Cost Challenges and Development Opportunities
The cost of raw materials accounts for 65%-70%. The average price of zinc ingots in 2024 was 24,800 yuan per ton, increasing by 6.7% compared to the previous year, and the price of cold-rolled steel plates rose by 4.2%. The profit of the extrusion industry reached 14.3%. Leading enterprises have controlled the volatility of costs within ±5% through means such as futures hedging and real-time monitoring systems.
The export market has performed well, with 12.8 million tons exported in 2024, increasing by 8.7% compared to the previous year. Southeast Asia holds a core share, with growth rates exceeding 12% in markets such as Vietnam and Indonesia. Future growth will focus on two directions: the demand for high-performance products brought by new energy vehicles and 5G communication, as well as the upgrade of environmental protection processes under the "carbon neutrality" goal. It is expected that the global market size will reach 2.902 billion US dollars by 2030.
