New Trends in the Fastener Industry: Transformation and Breakthrough of Steel Ring-Shaped Flat Head Nails

The steel ring-shaped flat-head nails, as an important category in the field of metal fasteners, enjoy excellent connection stability and adaptability, and are widely used in construction, furniture manufacturing, industrial assembly, and other scenarios. Recently, driven by the adjustment of downstream demand structure, the tightening of environmental protection policies, and technological iterations, the industry is undergoing a transformation from extensive expansion to high-quality development. It presents distinct characteristics in product performance, production processes, and market patterns.
The core advantages of the product and the direction of technological upgrading are clear. This type of nail uses high-quality steels such as SWRCH35K and ML35 as core raw materials. The unique continuous ring-shaped thread design is its core competitiveness, which can form a friction-locking composite connection mechanism, with the holding force being 2.3 times higher than that of traditional round nails. Data shows that the Φ6mm specification product has an extraction force of 8.7kN in southern pine wood and an ultimate anti-pulling force of 12.4kN in concrete, meeting the requirements of heavy-load scenarios. The technological upgrade focuses on three directions: upgrading the surface treatment to a "hot-dip galvanizing + organic coating" composite system, with the corrosion resistance duration of salt spray tests exceeding 1000 hours; the three-edge self-drilling design increases the installation speed by 40%, and the torque grading system optimizes the installation qualification rate to 96.7%; the rolling strengthening process is applied to extend the fatigue life and meet high-frequency alternating load scenarios.
Green manufacturing has become the core mainline of industry transformation. Under the guidance of the "dual carbon" goals, the penetration rate of short-process steelmaking technology has continued to increase. By using recycled scrap steel as raw materials with a ratio exceeding 70%, the carbon footprint per unit product can be reduced to 1.52 kg CO₂e/kg, a decrease of 36.1% compared to traditional processes. Leading enterprises have introduced induction heating quenching technology to replace traditional furnace heating, increasing energy utilization efficiency to over 78%. The accompanying waste heat recovery system further reduces energy consumption. At the same time, the closed-loop zinc recovery system has increased the zinc slag recovery rate in the galvanizing process to over 92%, establishing a "raw materials - production - recycling" circular system. The green process penetration rate has become the core competitiveness of enterprises.
The market landscape shows an increase in concentration and a differentiation in demand. By 2025, the industry's capacity utilization rate will rise to 78.9%, with supply and demand approaching a tight balance. The market share of the top ten enterprises will reach 43.7%, a significant increase compared to previous years. The clusters in East China and South China contribute 62% of the national production capacity. Leading enterprises in Zhejiang and Hebei have reduced costs through vertical integration of the industrial chain, and some enterprises have a self-sufficiency rate of 75% for cold heading steel wire rods. The demand side shows a clear differentiation. The application of prefabricated buildings accounts for 47.3% and has become the largest downstream sector. The demand in emerging fields such as photovoltaic brackets and new energy vehicles is growing rapidly, with an annual demand for photovoltaic bracket systems reaching 98,000 tons. In terms of prices, the average price of ordinary carbon steel products is 8-12 yuan per kilogram, while high-end anti-corrosion and high-strength products have significant premiums, with a price range of 15-25 yuan per kilogram.
The industry still faces challenges and opportunities. High-end products still rely partially on imports, and there is a vast space for domestic substitution. Some domestic enterprises have achieved a breakthrough in the domestic production of special steel grades with low-temperature toughness in the Sichuan-Tibet Railway project. In the future, with the popularization of digital production lines and the integration of BIM-MES data, the customization delivery cycle will be further shortened. Collaborative innovation among industry research, education, and production will promote the implementation of recyclable design and intelligent monitoring technologies, and the industry will continue to advance towards higher value-added, green, and intelligent directions.
