Rapid Advancement in High-end And Green Technologies —— Industry News Summary Of Steel Galvanized Flat-head Screws

Steel galvanized flat-head screws, as the basic connection components in mechanical assembly, building installation, home appliance manufacturing, and new energy equipment, are a core category with large usage and strong versatility in the fastener industry. Since 2026, affected by fluctuations in raw material prices, the implementation of new national standards, environmental upgrades, and changes in downstream demand structure, this category has shown clear industry trends in production, quality, price, and market structure.
Recently, the prices of carbon steel wire rods at the upstream have been fluctuating continuously, coupled with the high volatility of zinc ingots, have pushed the production cost of steel galvanized flat-head screws to rise significantly. To alleviate the cost pressure, many fastener enterprises in China have successively raised their factory prices at the end of February, with the increase ranging from 8% to 15%. The clusters in East China and South China have taken the lead in adjusting. Due to the low proportion of screws in the cost of end products, this price increase has not led to a significant increase in the prices of end products, but has exerted certain pressure on the profits of small and medium-sized manufacturing enterprises. At the same time, leading enterprises have stabilized costs through long-term contracts, futures hedging, and vertical integration, while small and medium-sized enterprises have adopted sales-based production and followed the market, further intensifying industry differentiation.
Quality and standard upgrades have arrived at an important stage. The new national standard GB/T 5780-2025 "Hexagon Head Bolts Class C" was officially implemented in February 2026, clearly strengthening technical requirements for hot-dip galvanizing layers, dimensional tolerances, and defect control, reconstructing the length specification system, and aligning with international standards, enhancing the product's universality and export adaptability. Industry inspections show that some small and medium-sized enterprises still have problems such as uneven zinc layer thickness, non-compliant adhesion, and lax tolerance control. Unqualified products are prone to rust in high-humidity and coastal environments, affecting the safety of projects and equipment. With stricter supervision and accelerated market screening, the production capacity of non-compliant small factories will continue to be cleared.
Process and green transformation have become the mainstream direction of the industry. To meet the weather resistance requirements of new energy, rail transit, and outdoor infrastructure, steel galvanized flat-head screws are upgrading towards higher corrosion resistance, environmentally friendly without chromium, and thicker zinc layers. The rapid popularization of environmentally friendly galvanizing, zinc-aluminum rare earth alloy coating, etc., has increased the salt spray test duration from the traditional 480 hours to over 720 hours, and some high-end products have exceeded 1000 hours. At the same time, green technologies such as no-chrome passivation, low-energy heat treatment, and digital detection have increased their penetration rate, with the number of enterprises certified by ISO14064 increasing significantly, and the proportion of recycled steel steadily rising, promoting the industry's transition to low-carbonization and standardization.
Downstream demand presents a structural feature of "stable in traditional fields, growth in high-end areas". Traditional fields such as construction, home appliances, and general machinery maintain stable demand, while the demand for high-strength and high-corrosion-resistant flat-head screws in new energy vehicles, photovoltaic brackets, and energy storage equipment is growing rapidly. In the overseas market, the benefits of RCEP continue to be released, with a faster growth rate in exports to ASEAN, but markets such as Ukraine have successively initiated anti-avoidance investigations, increasing trade compliance risks, forcing enterprises to standardize customs declaration, tax filing, and export processes.
Overall, in the recent period, the steel galvanized flat-head screw industry is in a critical period of cost pressure, standard upgrading, and structure optimization. Raw material and environmental policies have promoted the increase in industry concentration, new national standards and high-end demand have accelerated technological iteration, and quality compliance and cost control have become the core competitiveness of enterprises. In the future, enterprises with automated production lines, stable coating processes, and full-chain detection capabilities will occupy an advantage, the low-quality homogeneous competition will gradually shrink, and the industry will steadily advance towards high quality, high-end, and green.
