The green galvanization technology leads the way, and carbon steel round-head screws empower development in multiple fields.

Carbon steel galvanized round-head screws, as a key category of mechanical universal components, are widely used in fields such as construction, automobiles, new energy, and rail transportation due to their controllable costs, excellent corrosion resistance, and convenient installation. Recently, influenced by policy guidance, technological innovation, and adjustments in the global trade landscape, the industry is accelerating its transformation towards higher-end and greener development. The market structure and competition logic have undergone significant changes.
At the policy level, environmental protection and carbon constraints have become the core driving forces for the industry's reshuffling. The "Guidelines for Carbon Footprint Accounting of Bolts" to be implemented in 2026 will eliminate 15%-20% of high-energy-consuming and outdated production capacity, forcing enterprises to optimize their production processes. Among them, the EU Carbon Border Adjustment Mechanism (CBAM) has a profound impact. Starting from 2026, bolts, screws, and other steel products will be officially included in the control scope, and products exported to the EU will need to bear additional carbon emission costs. Based on the current carbon price, the unit product cost may increase by 12%-15%. Driven by the domestic "carbon neutrality" goal, traditional high-pollution galvanizing processes are gradually being replaced, and environmental compliance has become the bottom line for the survival of enterprises.
The technological upgrade focuses on optimizing the hot-dip galvanizing process and developing high-end products. Leading enterprises have solved industry pain points through a full-process innovation. The pretreatment stage adopts a combined process of alkaline degreasing and precise acid washing to remove surface oils and iron oxide scale. During the post-treatment stage, zinc chloride ammonium solution is applied to form a protective film, enhancing the wetting property of the zinc solution. During the high-temperature galvanizing process, the reaction temperature is strictly controlled at 445-465℃ to form a three-layer composite coating structure, with a protection life of up to 30-50 years. At the same time, the development of 10.9 grade and above high-strength products has been accelerated, and the penetration rate of technologies such as nano-coating and chrome-free passivation has increased, meeting the needs of high-end fields such as new energy vehicles and offshore wind power.
The market landscape exhibits characteristics of polarization and regional reconfiguration. The demand for high-end products is strong. By 2025, the demand for bolts in the offshore wind power sector has exceeded 150,000 tons, and the market size of high-strength screws for automobiles has reached 4.2 billion yuan. Leading enterprises such as Jin Yi Industry have invested 360 million yuan to build a digital factory, with the capacity utilization rate rising to over 85%. The low-end market, however, is facing pressure of overcapacity. In 2025, the capacity utilization rate may drop to 68%. Small and medium-sized enterprises are accelerating their relocation to the central and western regions, forming regional production bases relying on the Chengdu-Chongqing and the middle reaches of the Yangtze River urban agglomerations.
The international trade market is undergoing structural adjustments. Due to the trade barriers imposed by the EU, enterprises have shifted their focus to RCEP agreement countries and markets along the Belt and Road Initiative. Emerging markets such as Vietnam and Indonesia have maintained an annual demand growth rate of over 12%. Xinjiang's export volume to Central Asian countries has increased by more than 50% year-on-year. At the same time, the process of import substitution is accelerating, and domestic enterprises' market share in mid-to-high-end product sectors continues to expand. The scale of imported carbon steel screws is expected to shrink to around 1.2 billion yuan by 2025.
In the future, the focus of industry competition will be on carbon footprint management, intelligent production and global layout. Enterprises need to accelerate the establishment of a carbon footprint accounting system, promote the application of digital twins and AI quality inspection technologies, and at the same time, deeply explore high-value-added niche markets. Only in this way can they achieve sustainable development under policy constraints and market competition. Overall, the industry is undergoing a transformation period of both quantitative and qualitative improvement, and market concentration will continue to increase.
