Galvanized cold heading steel wire rods, as a key subcategory in the field of metal materials, are composite materials formed by cold working and galvanized treatment. They possess the advantages of high strength, high toughness, excellent corrosion resistance and precise forming, and widely support the development of core industries such as automotive manufacturing, new energy equipment and construction engineering. Recently, driven by the triple forces of policy guidance, technological innovation and upgraded market demand, the industry is accelerating its transformation towards high-end, green and intelligent development, forming a new development pattern featuring an optimized supply and demand structure and accelerated technological iteration.
The continuous expansion of product features and application fields is the core support for the development of the industry. Compared with ordinary steel, galvanized cold-heading steel wire rods enhance the material's density through the cold heading process. After galvanizing treatment, their corrosion resistance is significantly improved, and the surface roughness can be stably maintained within the range of 0.8 to 1.6 microns, with dimensional accuracy controlled at the ±0.01 millimeter level. In downstream applications, the automotive sector has the highest proportion, reaching 42% in 2023. Among them, the usage of new energy vehicles per vehicle increases by 30% to 40% compared to traditional fuel vehicles, mainly used in core components such as power battery structural parts and fasteners for electric drive systems. The demand for new energy equipment is growing rapidly. The compound annual growth rate of zinc-aluminum-magnesium coated wire rods for photovoltaic brackets exceeds 28%. The construction of wind power towers and ultra-high voltage power grids has also driven the demand for related products to increase by 18% year-on-year. In addition, in fields such as agricultural machinery equipment, 3C electronics, and aerospace, its application scope is constantly expanding. For instance, the 0.8-millimeter-level micro-cold heading technology for micro fasteners has achieved a breakthrough and holds a 75% market share of global micro screws for smartphones.
Remarkable achievements have been made in driving industrial upgrading through technological innovation. Leading domestic enterprises have achieved mass production of high-strength and high-toughness products with a tensile strength of over 1200MPa and a reduction of area of 60%. Their performance is close to the international advanced level. The domestic substitution rate has increased from 68% in 2020 to 78% in 2023. At the production process level, the penetration rate of controlled rolling and controlled cooling (TMCP) technology reached 65% in 2023 and is expected to exceed 85% by 2030. Combined with low-alloy and microalloyed composition designs, it effectively enhances the strength and toughness of materials. Intelligent transformation has been comprehensively advanced. Enterprises such as Baowu and Ansteel have established full life cycle management systems, achieving full traceability from order to delivery, and the product defect rate has dropped below 0.3%. Ma Steel has built the first fully intelligent production line in China, with an annual output of 400,000 tons of high-end products. The production line efficiency has increased by 20%, and the energy consumption per ton of steel has been reduced by 15%. Meanwhile, environmentally friendly processes have been rapidly popularized. Technologies such as chromium-free electroplating and circulating water cooling have reduced pollutant emissions, and the zinc slag recovery rate has reached 98%, meeting the requirements of green manufacturing.
The dual guidance of policy and market is reshaping the industry landscape. At the policy level, "Made in China 2025" has listed high-performance metal materials as a key direction. The Ministry of Industry and Information Technology has included alloy cold upsetting steels such as ML40Cr in the first batch of application demonstration subsidy scope. The Ministry of Ecology and Environment's "Ultra-Low Emission Transformation Plan for the Steel Industry" requires the completion of relevant capacity transformation by 2025, promoting the elimination of backward production capacity in the industry. The regional layout features "three clusters and two belts". The Yangtze River Delta, the Pearl River Delta and the Bohai Rim concentrate 75% of the country's production capacity. The output value of the Yangtze River Delta region accounts for 58%. Relying on its energy advantages, the central and western regions will add more production bases with an annual output capacity of over one million tons. In the market, the total domestic production capacity of cold heading steel wire rods was 8.5 million tons in 2023, with a utilization rate of 82%. It is expected that the market size will exceed 65 billion yuan by 2025. The export market has become a new growth point. In 2023, the export volume reached 680,000 tons, increasing by 17.2% year-on-year, with the ASEAN market accounting for 39%.
The future development of the industry is characterized by both opportunities and challenges. With the expansion of the new energy industry and the upgrading of high-end manufacturing, the compound annual growth rate of the market size is expected to remain at 8% to 10% from 2025 to 2030. However, at the same time, the EU's Carbon Border Adjustment Mechanism (CBAM) has increased the carbon costs of export enterprises, and the investment in environmental protection renovations has raised equipment costs. The industry concentration will further increase. It is estimated that the number of enterprises will shrink from 326 to around 150 by 2030, and the market share of the top 5 enterprises will exceed 45%. Enterprises need to continuously increase their investment in research and development, focus on breakthroughs in high-end products and upgrades in green processes, in order to seize the development opportunities of the industry.
