Galvanized wire is a metal wire made from low-carbon steel wire with a zinc coating on the surface. It uses the cathodic protection effect of zinc to prevent the corrosion of the steel substrate. According to the coating process, it is mainly divided into electro-galvanized wire and hot-galvanized wire. Hot-galvanized wire has a thicker zinc layer, usually ranging from 45 to 300 g/m², while electro-galvanized wire has a zinc layer of 10 to 50 g/m². There are significant differences in corrosion resistance, processing performance, and cost between the two.
In terms of market size, the galvanized wire industry has a promising future. In 2023, the market size of galvanized wire in China was approximately 42 billion yuan, and it is expected to increase to 52 billion yuan in 2025, with a compound annual growth rate of about 7.4%. The global market size is expected to reach 2.175 billion US dollars in 2025 and is expected to grow to 3.288 billion US dollars by 2032, with an average annual compound growth rate of 6.08% (2025 - 2032). The construction industry is the largest application field, accounting for about 45%, and is mainly used for steel bar binding, building structure reinforcement, etc. With the acceleration of global urbanization, the demand for galvanized wire in the construction industry continues to grow. The transportation sector, such as railway and highway construction, also has increasing demand. In the energy sector, zinc-aluminum alloy coating and other new anti-corrosion materials are also commonly used for reinforcing and protecting oil and gas pipelines. In the agricultural sector, it is mainly used for agricultural facility construction and maintenance. The development of these fields provides a broad market space for the galvanized wire industry.
The industry competition pattern shows the characteristics of "head concentration and small-scale differentiation". The global major players include large steel enterprises such as Baowu Steel, CITIC-TaiFu Steel, and Japan JFE Steel. They have significant advantages in technology, brand, and market share. The combined market share of the top ten enterprises reaches 52.3%, and leading enterprises such as Baosteel and Ansteel have improved product value through technological upgrades, with the proportion of high-end galvanized wire products (zinc layer thickness ≥ 275 g/m²) exceeding 60%, and the gross profit margin remains at 18% - 22%. However, a large number of small enterprises account for a significant proportion, and some rely on flexible business strategies and local advantages to occupy a certain market share, but they also face the pressure of rising environmental protection costs. In 2023, the investment in environmental protection equipment in the industry increased by 34% year-on-year, approximately 12% of the outdated capacity was eliminated.
The technological development of the galvanized wire industry is rapid. The hot-galvanizing process is still the mainstream, accounting for about 85%, but the electro-galvanizing technology has penetrated the precision component field due to its environmental protection advantages, reaching a penetration rate of 11%. At the same time, the research and development of new anti-corrosion materials such as zinc-aluminum alloy coatings has an annual growth rate of 25%, and it is expected to form a new material market of 3 billion yuan by 2025. Future technologies will focus more on environmental protection and efficiency. Environmental policies prompt enterprises to research and develop environmental protection technologies to reduce pollution emissions, and efficient production technologies will also become an important development direction, driving the industry towards green, efficient, and intelligent development.
The policy environment has a significant impact on the industry. Under the "carbon neutrality" goal, the industry faces pressure to reduce energy consumption and emissions, prompting enterprises to adopt green production technologies, such as chrome-free passivation processes have covered 65% of enterprises above a certain scale, and the wastewater discharge per ton of products is reduced by 40% compared to traditional processes. Relevant technical standards of "Made in China 2025" and other technologies promote enterprises to improve product quality and technological level. Some local policies on production restrictions and emissions control and compliance requirements also prompt enterprises to increase environmental protection investment and optimize production processes.
The industry development also faces many challenges. Raw material prices fluctuate greatly, such as zinc prices and steel prices, which affect the costs and profits of enterprises. There are cyclical changes in downstream demand, and economic environment, policy adjustments, etc., will cause fluctuations in the demand for galvanized wire in the construction, transportation, and other industries. International trade frictions have also had an impact on exports. For instance, Canada initiated an anti-dumping investigation into carbon steel wires and alloy steel wires related to China. Although Canada is not a major export market, it is necessary to be vigilant as other economies may follow suit.
In the future, the demand structure of the galvanized wire industry will tilt towards the new energy sector. It is expected that the demand for galvanized wires used in photovoltaic racks will exceed 8 million tons by 2025, with a compound annual growth rate of 15%. Intelligent production will accelerate its penetration. The automation rate of galvanized lines based on the industrial Internet of Things will increase from 47% in 2023 to 65% in 2025, and the labor cost per line can be reduced by 30%. Green manufacturing will become the core competitiveness. The proportion of recycled zinc required will be raised from the current 12% to 20% in 2025, promoting enterprises to establish closed-loop recycling systems.
